Abstract

I am the students of Haryana Engineering College, Jagadhri and studying

in CSE 7th semester. As a part of four year degree course we have

undergone a project as a work on “Manage – All” to facilitate them with

automated software besides the error prone manual work.

Present is the age of computers and technology. Practical knowledge has

its own importance. Without practical knowledge one can not be

specialized in one’s field. We have automated the practical knowledge of

institutes and their work in the project.

The technology used in this project is C++. This report provides the

knowledge regarding the platform used in the project.

In this project, we have tried best to incorporate the knowledge we have

about this department.

ACKNOWLEDGEMENT

To matter what accomplishment we achieve somebody helps me. For every accomplishment we need the cooperation and help of others. As knowledge advances by steps not by leaps so, ability advances by encouragement and guidance. Although you have ability and knowledge but it is worthless unless and until you can develop it if somebody encourages you.

While developing the project, I have learnt a lot. Firstly I got the explosure to the industry. We got to learn the work culture of a company. This will be an unforgetful experience. While developing this project, a lot of difficulties were faced by me. But it was the help of some special people that I have gained much confidence and developed the project quite well. Hereby, I shall like to thank all the employees of NIC to coordinate with me and provide me the information needed to complete the analysis part of this project. I shall like to thank everyone who in anyway helped me in this project.

My heartiest thanks to Mr. Hari Chand , Training Coordinate Officer, NIC Chandigarh who helped me in providing the required infrastructure, good work culture, make me learn a lot of new things, guiding me throughout the project and for providing me such a golden opportunity to experience the work culture before actually working for a company.

At last I am greatly thankful to the lectures of HARYANA ENGINEERING COLLEGE (JAGADHRI) whose inspiration & teaching are strong tool for completion of this training.

Overview of Project

Objective of the Software

On the basis of analysis the following objectives are framed in order to achieve the required goals :-

To make information easily accessible.

Decrease complexity of business and management.

Analyze large amount of business data.

Select, sort & analyze data in an unlimited no. of ways.

Minimize data redundancy by eliminating duplicate entries.

It is used to create, close and modify the account.

It is used to display the list of accounts.

It is used to generate monthly report.

It is used for calculating the interest of an account.

It is used to display a transaction account.

16

Problem Listing

Main problems in the existing system:-

Searching cannot be performed, each and every record is to be checked manually in the database.

History of a particular case are only stored in files not in database.

Unable to get accurate, timely information.

Application not complete for existing business practices

Modifications are time consuming or not feasible

The software uses concepts of C++, hence doing all the tasks like Data Hiding, Data encapsulation, etc. the data or information about the customers within the bank is saved to files by using FILE HANDLING property of C++.

The software provides a user friendly environment to the DBA and helps him/her to enter the information properly, without any difficulty and then store it on files.

17

Initial Study

Introduction

The project “Manage - All” has been implemented to create, close, modify the

accounts regarding customers of a bank in a proper and safe manner. It can also

calculate the interest, see the transacation of an individual account. The main

objective of this project is to resolve the problems which a person faces regarding

information about its account.

There is a Data Base Administrator, who enters all the information about an

individual customer who as an account or wants to create,close,modify an account on

to the system and allows it to get stored at proper location using file handling.

Here we can also search particular customer on the basis of :

Account no.

Name of the customer.

Date when the account was created.

There are various tasks of entering, editing and managing customer account. To do

these tasks every organization hires a Data Base Administrator. But he/she who plays

the role of DBA can never to this task manually. This is because, there is very large

number of customers who have an account in bank and there are very large fields of

information related with a single customer. So, if we consider the whole scenario, we

will come to know that it is a very complex and difficult task which can never be done

manually. So, in order to remove this problem, we use computers to store the data.

The data in computer is stored with the help of SOFTWARE.

This project provides the DBA all those services, which he/she requires while

managing the database.

19

The software provides a user friendly environment to the DBA and helps him/her to

enter the information properly, without any difficulty and then store it on files.

The software uses concepts of C++, hence doing all the tasks like Data Hiding, Data

encapsulation, etc. the data or information about the customer within a bank is saved

to files by using FILE HANDLING property of C++.

The data stored on file is not understandable to any human, it is written in machine

language which can only be interpreted by a computer. Hence, it also provides

security from unwanted access to the data.

TECHNOLOGY USED IN THE PROJECT

C++ Description

History

Stroustrup began work on C with Classes in 1979. The idea of creating a new

language originated from Stroustrup's experience in programming for his Ph.D. thesis

In 1980 the name was C with classes but after that in 1983, the name of the language

was changed from C with Classes to C++. C++ is an extension of language C because

new features were added in C that’s why he name as C++ means C with an increment

operator. New features that were added to the language included virtual functions,

function name and operator overloading, references, constants, user-controlled free-

store memory control, improved type checking, and a new comment style (//).

The name "C++"

This name is credited to Rick Mascitti (mid-1983) and was first used in December

1983. Earlier, during the research period, the developing language had been referred

to as "new C", then "C with Classes".

According to Stroustrup: "the name signifies the evolutionary nature of the changes

from C".

Old problems

Traditionally, C++ compilers have had a range of problems. The C++ standard does

not cover implementation of name decoration, exception handling, and other

implementation-specific features, making object code produced by different compilers

incompatible; there are, however, 3rd-party standards for particular machines or

operating systems which attempt to standardize compilers on those platforms (for

example C++ ABI[2]), and now many compilers have adopted a secondary standard

for these items.

21

Future development

C++ continues to evolve to meet future requirements.

Philosophy

Bjarne Stroustrup describes some rules that he uses for the design of C++.

*C++ is designed to be a statically typed, general-purpose language that is as efficient

and portable as C

*C++ is designed to directly and comprehensively support multiple programming

styles (procedural programming, data abstraction, object-oriented programming,

and generic programming)

*C++ is designed to give the programmer choice, even if this makes it possible for

the programmer to choose incorrectly

*C++ is designed to be as compatible with C as possible, therefore providing a

smooth transition from C

*C++ avoids features that are platform specific or not general purpose

*C++ does not incur overhead for features that are not used

*C++ is designed to function without a sophisticated programming environment

Compatibility of C and C++

The C and C++ programming languages are closely related.

C++ introduces many features that are not available in C— C++ code is not valid C

code

Constructs valid in C but not C++

One commonly encountered differences is that C allows a void* pointer to be

assigned to any pointer type without a cast, whereas C++ does not; this idiom appears

often in C code using malloc memory allocation.

22

Another portability issue from C to C++ are the numerous additional keywords that

C++ introduced. This makes C code that uses them as identifiers invalid in C++.

There are many other C syntaxes which are invalid or behave differently in C++ :

The comma operator can result in an "l-value" (a quantity that can be used for

the left-hand side of an assignment) in C++, but not in C.

C does not allow a given typedef to be duplicated in the same scope, whereas

C++ allows redundant typedefs.

Enumeration constants (enum values) are always of type int in C, whereas

they are distinct types in C++ and may have size different from int.

C++ identifiers are not allowed to contain two or more consecutive

underscores, whereas C identifiers may.

C++ also changes some C standard-library functions to add additional const

qualifiers, e.g. strchr returns char* in C and const char* in C++.

In both C and C++ one can define nested struct types, but the scope is

interpreted differently (in C++, a nested struct is defined only within the

scope/namespace of the outer struct).

Non-prototype ("K&R"-style) function declarations are not allowed in C++,

although they have also been deprecated in C since 1990. Similarly, implicit

function declarations (using functions that have not been declared) are not

allowed in C++, but have also been deprecated in C since 1999.

C allows struct, union, and enum types to be declared in function prototypes,

whereas C++ does not. A struct, union, or enum declaration in C++ declares

an implicit typedef, while in C it does not.

In order to intermix C and C++ code, any C++ functions which are to be called from

C-compiled code must be declared as extern "C".

Language features

*Operators

*Objects

*Encapsulation

*Inheritance

23

*Polymorphism

*Polymorphism through inheritance

*Template functions and classes

*Operator overloading

*Function overloading

*Virtual member functions

*Criticism

C++ has been the subject of much debate. Some of the most commonly levelled

criticisms include:

Since C++ is based on, and largely compatible with, C, it also inherits most of

the criticisms levelled at that language.

Taken as a whole C++ is a large and complicated language, and so is difficult

to fully master. However, by its multi-paradigm approach programmers are

free to use the subset of C++ features that they're comfortable with, adding

new features to their repertoire only as required and at their own pace.

It is extremely difficult to write a good C++ parser .This is partly because the

C++ grammar is not LALR(1). Because of that, there are very few tools for

analyzing or performing non-trivial transformations (e.g., refactoring) of

existing code.

C++ is sometimes compared unfavorably with single-paradigm object-oriented

languages such as Java, on the basis that it allows programmers to "mix and

match" object-oriented and procedural programming, rather than strictly

enforcing a single paradigm. This is part of a wider debate on the relative

merits of the two programming styles.

The abundance of language features can lead less experienced programmers to

bring unnecessarily advanced or complicated solutions to simple problems.

For embedded systems C++ is sometimes considered too bloated, especially

for language features like exceptions and RTTI which add to code size. Thus

Embedded C++ standard has been specified, but has also received criticism for

leaving out useful parts of the language that incur no runtime penalty.

24

C++ Glossary:

25

Aarguments, function - Arguments in function declarations may have names, but the

names are ignored (they are positional). In C++ (unlike C), an empty argument list

means a function with no arguments, since the C "wild card" style would prevent

type-checking, e.g., int func2(); this behavior is different than the result you would

have expected in C.

Assignment operator: = *= /= %= += -= <<= >>= &= ^= != "All require an

lvalue as left operand, and the lvalue must be modifiable: it must not be an array, and

must not have an incomplete type, or be a function." .At least the = operator is

overloadable.

Automatic type conversion - e.g., casting a short to a void pointer (cannot do

the reverse in C++).

B

Base class - The most generalized class in a class structure. Most applications have

many such root classes. Some languages define a primitive base class, which serves as

the ultimate superclass of all classes.

C

Character constant - single byte char enclosed by single quotes.

Class - An abstract data type. A keyword which defaults a struct class to private. A

class binds into one unit the data structure and its functions, also called a user-defined

type. Variables, or instances of that class, are called objects.

D

Declaration -

26

Dynamic memory allocation - In C and Pascal, a method to create space for

variables at run time. For situations where you don't know at compile time how many

objects you'll need, or what their lifetimes (scope) will be.

specifies to the compiler the types of all the elements of an identifier; "this function or

this piece of data exists somewhere else, and here is what it should look like."

Declarations normally go in header files with extensions of .h.

Derived class - declaration keyword specifying that a declared class has

inheritance of all of the data members and member functions of the class from which

it is declared to derive, e.g., class Derived : Base.

Derived objects receive their own copies of called base object members. The compiler

automatically calls constructors and destructors for called copies.

E

Extern - keyword in C and C++ to help tell the compiler or user how to distinguish a

definition from a declaration, when the definition is elsewhere, e.g.,

extern int func1(int length, int

width);

F

Friend - keyword designating a class or single member function as having access to

(1) a specified entire class, (2) a member function of another class, or (3) a designated

nonmember function. If a friend declaration omits function's parameters, compiler

checks for functions or overloaded functions with matching signatures, else reports

error.

function declaration - in C and C++, gives the function name, the argument types

passed to a function, and the return type of the function; e.g.,

int func1(int, int);

27

H

Header file

Function definition - looks like function declarations, except with bodies,

collections of statements inside curly braces, e.g.,

int func1(int length, int width) { ...}

The arguments in the function definition must have names if you also want to use the

arguments in the function body; otherwise, they are optional.

- contains the external declarations for a library, using a filename extension

of .h . To use a library, you must include its header file. The programmer who

provides the library provides the header file; to include it, use the #include

preprocessor directive, and the compiler will insert it if the search is

successful:

#include "local.h" //search the current directory;

//report err if file does not exist.

#include <local.h> (use LT & GT brackets)

//search another, specified

//environment

In C, a header file should not contain any function or data defs because the header can

be included in more than one file, causing the linker to complain. In C++, there are

two exceptions: inline, and const.

I

Inheritance - A C++ property which allows the defining of one class in terms of

another. The compiler physically implements inheritance by making a copy of the

data structure of the original base class into a declared derived class, and providing

28

access to the member functions ion the base class. Inheritance allows you to add or

modify members without corrupting the original class code. Conserves effort, and

creates extensible programs through sub classing.

Inline function - keyword forcing compiler to copy body of a called function into

the calling function. Best for recursive and loop calls. Provides type safety and side-

effects protection not afforded by #define.

L

Lvalue - "An lvalue is an expression referring to an object ... an object is a named

region of storage" . The left-hand side of the assignment operator (=) equation; what

the rvalue is copied into.

M

Manipulators - special iostream functions permitting specific i/o operations while

in the middle of stream insertion or extraction. These functions switch appropriate

iostream format flags.

O

Object - a named region of storage (whether it has yet been allocated or not).

Operator overload - Compiler replacement of a C++ operator with a function

called to overload it with a new meaning. Form: operator<c++ operator>; Example:

float operator+(parm1, parm2){return (...)} would intercept and replace the plus (+)

operator. Operator overloading means you can give an operator like + or - a special

meaning when used with a new data type you create.

P

Pointers vs. references (USG) - a pointer must be dereferenced to access what

it points to; a reference need not be. The entity to which a reference refers may only

29

be set when the reference is created; in this respect it is somewhat like a const pointer

that gets a virtual * put in front of it when it is used, and puts a virtual ampersand in

front of the expression from which it is initialized.

Polymorphism - lets you use objects of different classes by means of the same

program element (CRS); use of identical interfaces with different implementations

(CIO p.18). A program designed around polymorphism manages a collection of base-

class objects, and the precise result of a message sent to one of these cannot be

determined at compile time, since only the base class is known, not the subclass.

Polymorphism is the proper behavior of a derived-class object when treated as a base-

class object .. The specific function called is determined at run time.

S

Scope - Generally, the domain of objects and calls within which an object can exist.

A struct name or enum in an inner scope can obscure a global of the same name in an

outer scope. In C++, enum constants embedded in a struct def have the same scope as

that struct's fields.

Scope resolution operator (::) - operator telling compiler to look outside the

current block for variable of the same name (e.g., a global, or a member function of a

base class.)

Static member - like a global variable whose scope is limited to the class in which

it is declared. Especially true if declared as private or protected.

Static data member - shared by all objects of a class for each instantiation of that

template class. All static data members are defined within the scope of the file in

which they exist, by prefixing the definition with a template specification. The def

should appear in that .cp file, not in the header. Like globals, automatically initialized

to 0.

30

Static member function - a member function declared as static; can access and

modify static data members; cannot be of type const or virtual.

String constant - zero or more chars surrounded by double quotes.

Structure - an object "consisting of a sequence of named members of various

types" , typically containing one or more data members, and/or member functions

which specify the list. May not contain a member of incomplete type.

Struct - Structure; keyword whose default structure class is public.
