WORD


MICROSOFT WORD

Word processor is used to produce documents for business or personal use

such as newsletter, reports, letters and essays. We might say that a word processor

is an intelligent typewriter. We can type a whole page, make corrections (editing),

use up paragraphs in different styles and shapes and columns (formatting) and also

check spelling, find and insert synonyms for a word (Thesaurus) and process it in

many more ways before we actually put that page to print.

FEATURES OF WORD PROCESSOR

The following are the main features of a word processor:

Fast

Editing features

Permanent storage

Formatting features

Graphics

C PROGRAMMING


INTRODUCTION TO C PROGRAMMING:

C is a structured language.

A structured language allows variety of programs in small modules.

It is easy for debugging, testing and maintenance.

C is an imperative (procedural) systems implementation language.

It was designed to be compiled using a relatively straight forward compiler, to

provide low level access to memory, to provide language constructs that map

efficiently to machine instruction and to require minimal run–time support.

A program is a set of instructions for performing a particular task. This

written program is called as source program.

The source program to be converted to the machine language. Which is called

as object program. Either Interpreter or Compiler will perform this function.

An Interpreter reads only one line of a source program at a time and

converts it to object code. Error will be indicated instantly.

A Compiler reads the entire program and converts it to the object code. It

provides the error not one but errors of the entire program.

Date :


AIM:

To write a program in C to find the Factorial of the given number

ALGORITHM:

Step 1: Start

Step 2: Read input value n

Step 3: Call and Print function fact (n)

Step 4: Stop

Step 1: Function fact start

Step 2: In n=0 returns 1 else go to step 3

Step 3: return (n*Fact (n-1))

READ the value of n

If (n==0)

WRITE the value 1

Else

Calculate Fact (n) = (n*Fact(n-1))

WRITE the output Fact (n)
