Program to find factorial of given number in c language.

Factorial ->

Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!

■ For example:

                  *     5! = 5*4*3*2*1 = 120  

                  *      3! = 3*2*1 = 6

■Program for find the factorial of a number -

#include<stdio.h>

#include<conio.h>

void main()

{

 int n,fact=1;

 int i;

 clrscr();

 printf("Enter a number=");

 scanf("%d",&n);

 for(i=1; i<=n; i++)

 {

   fact=fact*i;

 }

 printf("the factorial of no. is=%d",fact);

 getch();

 }
