Training Report
3.1 INTRODUCTION to C
Dennis Ritchie designed and implemented the first C compiler on a PDP-11 (a prehistoric machine by today's standards, yet one which had enormous influence on modern scientific computation). The C language was based on two (now defunct) languages: BCPL, written by Martin Richards, and B, written by Ken Thompson in 1970 for the first UNIX system on a PDP-7. The original ``official'' C language was the ``K & R'' C, the nickname coming from the names of the two authors of the original ``The C Programming Language''. In 1988, the American National Standards Institute (ANSI) adopted a ``new and improved'' version of C, known today as ``ANSI C''. This is the version described in the current edition of ``The C Programming Language -- ANSI C''. The ANSI version contains many revisions to the syntax and the internal workings of the language, the major ones being improved calling syntax for procedures and standarization of most (but, unfortunately, not quite all!) system libraries.
The code starts with a series of comments indicating its the purpose, as well as its author. It is considered good programming style to identify and document your work (although, sadly, most people only do this as an afterthought). Comments can be written anywhere in the code: any characters between / and / are ignored by the compiler and can be used to make the code easier to understand. The use of variable names that are meaningful within the context of the problem is also a good idea.
The #include statements now also include the header file for the standard mathematics library math.h. This statement is needed to define the calls to the trigonometric functions atan and sin. Note also that the compilation must include the mathematics library explicitly by typing
gcc sine.c -lm
3.1.1 Data Types
Variable names are arbitrary (with some compiler-defined maximum length, typically 32 characters). C uses the following standard variable types: int -> integer variableshort -> short integerlong -> long integerfloat -> single precision real (floating point) variabledouble -> double precision real (floating point) variablechar -> character variable (single byte)The compilers checks for consistency in the types of all variables used in any code. This feature is intended to prevent mistakes, in particular in mistyping variable names. Calculations done in the math library routines are usually done in double precision
5
arithmetic (64 bits on most workstations). The actual number of bytes used in the internal storage of these data types depends on the machine being used.
The printf function can be instructed to print integers, floats and strings properly. The general syntax is
printf( "format", variables );where "format" specifies the converstion specification and variables is a list of quantities to print. Some useful formats are %.nd integer (optional n = number of columns; if 0, pad with zeroes)%m.nf float or double (optional m = number of columns,
n = number of decimal places)%ns string (optional n = number of columns)%c character\n \t to introduce new line or tab\g ring the bell (``beep'') on the terminal
3.1.2 Loops
Most real programs contain some construct that loops within the program, performing repetitive actions on a stream of data or a region of memory. There are several ways to loop in C. Two of the most common are the while loop: while (expression) {
...block of statements to execute... }and the for loop: for (expression_1; expression_2; expression_3) {
...block of statements to execute... }The while loop continues to loop until the conditional expression becomes false. The condition is tested upon entering the loop. Any logical construction (see below for a list) can be used in this context.
The for loop is a special case, and is equivalent to the following while loop: expression_1;
while (expression_2) {
...block of statements...
expression_3; }
6
For instance, the following structure is often encountered: i = initial_i;
while (i <= i_max) { ...block of statements...
i = i + i_increment; }This structure may be rewritten in the easier syntax of the for loop as: for (i = initial_i; i <= i_max; i = i + i_increment) {
...block of statements... }Infinite loops are possible (e.g. for(;;)), but not too good for your computer budget! C permits you to write an infinite loop, and provides the break statement to ``breakout '' of the loop. For example, consider the following (admittedly not-so-clean) re-write of the previous loop: angle_degree = 0;
for ( ; ; ) {
...block of statements...
angle_degree = angle_degree + 10;if (angle_degree == 360) break;
}
4. Symbolic Constants You can define constants of any type by using the #define compiler directive. Its syntax is simple--for instance #define ANGLE_MIN 0#define ANGLE_MAX 360would define ANGLE_MIN and ANGLE_MAX to the values 0 and 360, respectively. C distinguishes between lowercase and uppercase letters in variable names. It is customary to use capital letters in defining global constants.
3.1.3 Conditionals
7
Conditionals are used within the if and while constructs: if (conditional_1) {
...block of statements executed if conditional_1 is true... } else if (conditional_2) {
...block of statements executed if conditional_2 is true... } else {
...block of statements executed otherwise... }and any variant that derives from it, either by omitting branches or by including nested conditionals.
Conditionals are logical operations involving comparison of quantities (of the same type) using the conditional operators:
< smaller than <= smaller than or equal to
== equal to!= not equal to>= greater than or equal to> greater than
and the boolean operators && and|| or! not
Another conditional use is in the switch construct: switch (expression) {
case const_expression_1:{ ...block of statements...
break;}case const_expression_2:{ ...block of statements...
break;}default:{ ...block of statements..
8
} }The appropriate block of statements is executed according to the value of the expression, compared with the constant expressions in the case statement. The break statements insure that the statements in the cases following the chosen one will not be executed. If you would want to execute these statements, then you would leave out the break statements. This construct is particularly useful in handling input variables.
3.1.4 Pointers
The C language allows the programmer to ``peek and poke'' directly into memory locations. This gives great flexibility and power to the language, but it also one of the great hurdles that the beginner must overcome in using the language.
All variables in a program reside in memory; the statements float x; x = 6.5;request that the compiler reserve 4 bytes of memory (on a 32-bit computer) for the floating-point variable x, then put the ``value'' 6.5 in it.
Sometimes we want to know where a variable resides in memory. The address (location in memory) of any variable is obtained by placing the operator ``&'' before its name. Therefore &x is the address of x. C allows us to go one stage further and define a variable, called a pointer, that contains the address of (i.e. ``points to'') other variables. For example: float x; float px;
x = 6.5; px = &x;defines px to be a pointer to objects of type float, and sets it equal to the address of x:
Pointer use for a variable
The content of the memory location referenced by a pointer is obtained using the `` '' operator (this is called dereferencing the pointer). Thus, px refers to the value of x.
C allows us to perform arithmetic operations using pointers, but beware that the ``unit'' in pointer arithmetic is the size (in bytes) of the object to which the pointer points. For example, if px is a pointer to a variable x of type float, then the expression px + 1 refers not to the next bit or byte in memory but to the location of the next float after x (4 bytes away on most workstations); if x were of type double, then px + 1 would refer to a location 8 bytes (the size of a double)away, and so on. Only if x is of type char will px + 1 actually refer to the next byte in memory.
9
Thus, in char pc; float px; float x;
x = 6.5; px = &x; pc = (char ) px;(the (char ) in the last line is a ``cast'', which converts one data type to another), px and pc both point to the same location in memory--the address of x--but px + 1 and pc + 1 point to different memory locations.
3.1.4 Arrays
Arrays of any type can be formed in C. The syntax is simple: type name[dim];
In C, arrays starts at position 0. The elements of the array occupy adjacent locations in memory. C treats the name of the array as if it were a pointer to the first element--this is important in understanding how to do arithmetic with arrays. Thus, if v is an array, v is the same thing as v[0], (v+1) is the same thing as v[1], and so on
8. Character Arrays A string constant , such as
"I am a string"is an array of characters. It is represented internally in C by the ASCII characters in the string, i.e., ``I'', blank, ``a'', ``m'',... for the above string, and terminated by the special null character ``\0'' so programs can find the end of the string.
String constants are often used in making the output of code intelligible using printf ; printf("Hello, world\n");printf("The value of a is: %f\n", a);
String constants can be associated with variables. C provides the char type variable, which can contain one character--1 byte--at a time. A character string is stored in an array of character type, one ASCII character per location. Never forget that, since strings are conventionally terminated by the null character ``\0'', we require one extra storage location in the array!
I/O to and from files
10
Similar statements also exist for handling I/O to and from files. The statements are
#include < stdio.h>
FILE fp;
fp = fopen(name, mode);
fscanf(fp, "format string", variable list); fprintf(fp, "format string", variable list);
fclose(fp );The logic here is that the code must define a local ``pointer'' of type FILE (note that the uppercase is necessary here), which is defined in < stdio.h> ``open'' the file and associate it with the local pointer via fopen perform the I/O operations using fscanf and fprintf disconnect the file from the task with fclose
3.1.5 Functions
Functions are easy to use; they allow complicated programs to be parcelled up into small blocks, each of which is easier to write, read, and maintain. We have already encountered the function main and made use of I/O and mathematical routines from the standard libraries. Now let's look at some other library functions, and how to write and use our own. Calling a Function The call to a function in C simply entails referencing its name with the appropriate arguments. The C compiler checks for compatibility between the arguments in the calling sequence and the definition of the function.
Library functions are generally not available to us in source form. Argument type checking is accomplished through the use of header files (like stdio.h) which contain all the necessary information. For example, as we saw earlier, in order to use the standard mathematical library you must include math.h via the statement #include < math.h>at the top of the file containing your code. The most commonly used header files are < stdio.h> -> defining I/O routines< ctype.h> -> defining character manipulation routines< string.h> -> defining string manipulation routines< math.h> -> defining mathematical routines< stdlib.h> -> defining number conversion, storage allocation and similar tasks< stdarg.h> -> defining libraries to handle routines with variable numbers of arguments
11
< time.h> -> defining time-manipulation routinesIn addition, the following header files exist: < assert.h> -> defining diagnostic routines< setjmp.h> -> defining non-local function calls< signal.h> -> defining signal handlers< limits.h> -> defining constants of the int type< float.h> -> defining constants of the float typeAppendix B in the K & R book describes these libraries in great detail. Writing Your Own Functions A function has the following layout: return-type function-name ( argument-list-if-necessary ){ ...local-declarations...
...statements...
return return-value;}If return-type is omitted, C defaults to int. The return-value must be of the declared type.
A function may simply perform a task without returning any value, in which case it has the following layout: void function-name ( argument-list-if-necessary ){ ...local-declarations...
...statements...}
Command-line argumentsIt is standard practice in UNIX for information to be passed from the command line directly into a program through the use of one or more command-line arguments, or switches. Switches are typically used to modify the behavior of a program, or to set the values of some internal parameters. You have already encountered several of these--for example, the "ls" command lists the files in your current directory, but when the switch -l is added, "ls -l" produces a so-called ``long'' listing instead. Similarly, "ls -l -a" produces a long listing, including ``hidden'' files, the command "tail -20" prints out the last 20 lines of a file (instead of the default 10), and so on.
Conceptually, switches behave very much like arguments to functions within C, and they are passed to a C program from the operating system in precisely the same way as arguments are passed between functions. Up to now, the main() statements in our programs have had nothing between the parentheses. However, UNIX actually makes available to the program (whether the programmer chooses to use the information or not) two arguments to main: an array of character strings, conventionally called argv, and an
12
integer, usually called argc, which specifies the number of strings in that array. The full statement of the first line of the program is main(int argc, char argv)(The syntax char argv declares argv to be a pointer to a pointer to a character, that is, a pointer to a character array (a character string)--in other words, an array of character strings. You could also write this as char argv[]. Don't worry too much about the details of the syntax, however--the use of the array will be made clearer below.)
When you run a program, the array argv contains, in order, all the information on the command line when you entered the command (strings are delineated by whitespace), including the command itself. The integer argc gives the total number of strings, and is therefore equal to equal to the number of arguments plus one

4.4 Software Development Lifecycle
FEASIBILILTY ANALYSIS
15
Feasibility study is done so that an ill-conceived system is recognized early in
definition phase. During system engineering, however, we concentrate our
attention on four primary areas of interest. This phase is really important as
before starting with the real work of building the system it was very important
to find out whether the idea thought is possible or not.
1 Economic Feasibility: An evaluation of development cost weighted
against the ultimate income or benefit derived from the developed system.
2 Technical Feasibility: A study of function, performance and constraints
that may affect the ability to achieve an acceptable system.
3 Operational Feasibility: A study about the operational aspects of the
system.
4.4.1 ECONOMIC ANALYSIS
Among the most important information contained in feasibility study is Cost
Benefit Analysis and assessment of the economic justification for a computer
based system project. Cost Benefit Analysis delineates costs for the project
development and weighs them against tangible and intangible benefits of a
system. Cost Benefits Analysis is complicated by the criteria that vary with
the characteristics of the system to be developed, the relative size of the
project and the expected return on investment desired as part of company’s
strategic plan. In addition, many benefits derived from a computer-based
system are intangible (e.g. better design quality through iterative optimization,
increased customer satisfaction through programmable control etc.)As this is
an in-house project for the company, to be used for its own convenience and
also it is not that big a project. So neither it requires a huge amount of money
nor any costly tools or infrastructure need to be set up for it.
16
Operational Feasibility
The project is operationally feasible. This project is being made for the
convenience of the patients and doctors only. This system will greatly reduce
a huge burden of doctors. So because of the above stated advantages the
users of the system will not be reluctant at all.
4.4.2 SYSTEM ANALYSIS
INTRODUCTION:
System analysis is the process of studying the business processors and
procedures, generally referred to as business systems, to see how they can
operate and whether improvement is needed.
This may involve examining data movement and storage, machines and
technology used in the system, programs that control the machines, people
providing inputs, doing the processing and receiving the outputs.
INVESTIGATION PHASE
The investigation phase is also known as the fact-finding stage or the analysis of
the current system. This is a detailed study conducted with the purpose of
wanting to fully understand the existing system and to identify the basic
information requirements. Various techniques may be used in fact-finding and all
fact obtained must be recorded.
A thorough investigation was done in every effected aspect when determining
whether the purposed system is feasible enough to be implemented.
17
INVESTIGATION
As it was essential for us to find out more about the present system, we used the
following methods to gather the information: -
1. Observation: - Necessary to see the way the system works first hand.
2 Document sampling: - These are all the documents that are used in the
system. They are necessary to check all the data that
enters and leaves the system.
3 Questionnaires: - These were conducted to get views of the other employees
who are currently employed in the system.
ANALYSIS OF THE INVESTIGATION
Strengths of the System
1. No complex equipment: - The equipment that is used is very simple and no
special skills have to be mastered to be able to
operate the system. Therefore no training is required
for the employees.
2. Low cost: - There is little money spent in maintaining the present
system other than buying the necessary office
equipment and the ledgers.
18
CONSTRAINTS AND LIMITATIONS
The constraints and limitation within a system are the drawbacks that occur
during the implementation of the system. These limitations and constraints can
crop up in almost every system; the most important fact is to find a way to
overcome these problems.
Software design is the first of three technical activities – design, code
generation, and test that are required to build and verify the software.
Each activity transforms information in manner that ultimately results in
validated computer software.
The design task produces a data design, an architectural design, an
interface design and component design.
The design of an information system produces the details that clearly
describe how a system will meet the requirements identified during
system analysis. The system design process is not a step by step
adherence of clear procedures and guidelines. When I started working on
system design, I face different types of problems; many of these are due
to constraints imposed by the user or limitations of hardware and software
available. Some times it was quite difficult to enumerate that complexity of
the problems and solutions thereof since the variety of likely problems is
so great and no solutions are exactly similar however the following
consideration I kept in mind during design phased.
Design objectives:-
19
The primary objective of the design is to deliver the requirements as
specified in the feasibility report. These are the some of the objectives,
which I kept in mind.
Practicality: The system is quite stable and can be
operated by the people with average intelligence.
Efficiency: I tried to involve accuracy, timeliness and
comprehensiveness of the system output.
Cost: It is desirable to aim for the system with a minimum
cost subject to the condition that it must satisfy the entire
requirement.
Flexibility: I have tried that the system should be modifiable
depending on the changing needs of the user. Such
modifications should entail extensive reconstructing or
recreation of software. It should also be portable to
different computer systems.
Security: This is very important aspect which I followed in
this designing phase and tried to covers the areas of
hardware reliability, fallback procedures, and physical
security of data.
20
4.4.3 INITIAL STUDY AND FEASIBILITY ANALYSIS
INITIAL STUDY
INTRODUCTION:
The first step in the Software Development Life Cycle (SDLC) is the
preliminary investigation to determine the feasibility of the system. The
purpose of the preliminary investigation is to evaluate project requests. It
is not a design study nor does it include the collection of details to
describe the business system in all aspect. Rather it is the collection of
the information that helps committee members to evaluate the merits of
the project request and make an informed judgment about the feasibility
of the proposed project.
The preliminary investigation should accomplish the following
objectives.
1. Clarify and understand the project request
2.Determine the size of the project.
3.Assess costs and benefits of alternative approaches.
4.Determine the technical and operational feasibility of alternative
approaches
5.Report the findings to management; with recommendations outlining the
acceptance or rejection of the proposal.
21
REQUIREMENT AND FEASIBILITY ANALYSIS
INTRODUCTION:
WHAT IS A FEASIBILITY STUDY?
Prior to stating whether the system we have to develop is feasible or not we
believe that we should emphasize on what is implied by the word “Feasibility”.
Feasibility is the measure of how beneficial or practical the development of the
system will be to the organization. It is a preliminary survey for the systems
investigation. It aims to provide information to facilitate a later in-depth
investigation.
The report produced at the end of the feasibility study contains suggestions and
reasoned arguments to help management decide whether to commit further
resources to the proposed project.
Within the scheduled duration we were assigned to study both the positive and
negative aspects of the current manual system, in which we have come up with
a number of drawbacks that prevent the progress of the clinic if it is continued to
function manually.
Having gone through all measures of feasibility we report to the management to
figure out if the objectives of the new system are met.
For e.g. - Is the system within the budget allowed for it?
Will the organizations needs, be met by the new proposed system as
Originally envisaged?
If and when the objectives of the system are met and the new system is
approved, then the more specific details in the proposal should be considered
and approved.
22
TYPES OF FEASIBILITY
There are various measures of feasibility that helps to decide whether a
particular project is feasible or not. These measures include-
1 Operational Feasibility
2 Technical Feasibility
3 Economical and Financial Feasibility
Each of these types will be explained in detail throughout the project report.
OPERATIONAL FEASIBILITY
A proposed system is beneficial only if it can be turned into an information
system that will meet the operational requirements of an organization. A system
often fails if it does not fit within existing operations and if users resist the
change.
Important issues a systems developer must look into are:
1 Will the new system be used if implemented in an
organization?
2 Are there major barriers to implementation or is proposed
system accepted without destructive resistance?
The whole purpose of computerizing the Tender System is to handle the work
much more accurately and efficiently with less time consumption. There will be
additional work to be completed, because now the contractors can submit their
tenders online. Their database is maintained separately.
23
Compared to the semi-computerized system the chances of avoiding errors in a
computerized system is much higher because the user need not stress himself
unnecessarily resulting in recklessness. Unlike the semi-computerized system
there would be backup data for all the information concerning the daily
transactions occurred within the organization.
If we are considering the performance and response time for each task, it is very
much faster since there is less paper work to be completed. When entering data
into the system to relieve the user from additional work and typing incorrect data,
the system provides options such as combo boxes, check boxes, option buttons
and etc. if the users type in incorrect data they would be informed immediately
about the error by the error detection control.
Another important fact to be regarded is the security control, which is handled by
the system. Since data regarding each contractor and the company is
confidential, security is a key issue. Information falling into the wrong hands
could jeopardize the entire organization. Unlike in semi-computerized systems
the proposed system offers adequate control to protect the organization against
fraud and embezzlement and guarantees the accuracy and security of data and
information. This is handled by the system providing each department and
individuals with separate login names and passwords.
The new system is more user-friendly, which enables the end-user to complete
his/her work efficiently and accurately with interest. After taking the above fact
into consideration we can state the operating of the proposed system within the
organization is feasible.
In this phase of the feasibility study the following two main topics
1 Technical Performance Aspect
2 Acceptance within the organization
24
Technical performance aspect is explained in the technical feasibility report and
there is no new information is needed in this to explain it again, but as for the
acceptance within the organization the following points are important and those
are explained according to the topics
1. Whether the system provides right information to the right place.
In the current system which is the semi computerized system the information
may be lost in the process of sending from one place to another. This is mainly
due to human interaction in the process of the transferring information from one
place to another.
2. Whether the new system affect the current users in the system
The new proposed system will affect the users in the following areas
Accuracy
Efficiency
Productivity
Robustness
Lesser time consuming
3. Skill and attitude
This system is developed according to the experience of the current employees
and the management structure, so for this system to function within the current
employee community. The employees do not need to have new skills other than
the skills which are gained in the current system.
25
4. Job restructuring and training
For the new system to have an effect in the organization the employees should
be give a proper training in operating the software and computer systems. If the
employee does not have the minimal experience should be given the proper
training
If the organization is reluctant to give a full training to the employees who require
the full knowledge organization can restructure the structure of the departments.
TECHNICAL FEASIBILITY
Based on the outline design of system requirements in terms of inputs, outputs,
files, procedures and staff, the technical issues raised during technical feasibility
include:
1 Does the necessary technology exist to do what is
proposed?
2 Does the proposed equipment have the technical capacity to
hold the data required to use in the new system?
3 Adequate responses provided by the proposed system?
4 Is the system flexible enough to facilitate expansion?
5 Is there any technical guarantee of accuracy, reliability, ease
of access and data security?
The system developer’s task is to view needed capabilities in light of currently
available technology. Since the existing system is semi-computerized it is clear
to us that there is no efficiency in the use of technology within the organization.
The solution is the implementing the new computerized system, which works
hand in hand with high technology.
26
A database has to be maintained in order to update and backup data whenever
a transaction occurs. To create databases we use SQL server.
After taking the above facts into consideration we can state that the new
proposed system is technically feasible.
SYSTEM SECURITY
System security is a vital aspect when it comes to developing a system. The
system should ensure the facility of preventing unauthorized personnel from
accessing the information and the data within the system. The system should
provide total protection for each user’s information so that the integrity of data is
sustained and also prevent hackers from hacking the system.
The proposed system ensures the security and the integrity of data. This is done
by providing a password login system for each authorized users. And for
example the System Administrator has access to all kinds of information.
By providing this facility information is properly managed and information is
protected. For example the system administrator’s day to day tasks are lessened
and easier because he doesn’t have to have a constant eye on the system and
worry about hackers hacking the system.
27
ECONOMICAL AND FINANCIAL FEASIBILITY
In making recommendations a study of the economics of the proposed system
should be made. The proposed system must be justifiable in terms of cost and
benefit, to ensure that the investment in a new/changed system provide a
reasonable return.
Cost-benefit analysis of information is complicated by the fact that many of the
systems cost elements are poorly defined and that benefit can often be highly
qualitative and subjective in nature.
In our proposed system various costs are evaluated. Even though finding out the
costs of the proposed project is difficult we and assume and estimate the costs
and benefits as follows.
According to the computerized system we propose, the costs can be broken
down to two categories.
1. Costs associated with the development of the system.
2. Costs associated with operating the system.

4.4.4 SOFTWARE REQUIREMENT SPECIFICATION
The software requirement specification is produced at the culmination of
the analysis task. The function and performance allocated to software as
part of system engineering are refined by establishing a complete
information description, a detailed functional description, a representation
of system behavior, an indication of performance requirement and design
constraints appropriate validation criteria, and other information pertinent
to requirement.
The introduction to software requirements specification states the goals
and objectives of the software, describing it in the context of the computer
based system.
The Information Description provides a detailed description of the problem
that the software must solve. Information content, flow and structure are
documented.
A description of each function required to solve the problem is presented
in the Functional Description.
Validation Criteria is probably the most important and ironically the most
often neglected section of the software requirement specification.
Software requirement specification can be used for different purpose.
Here are the major uses.
