PROCEDURE:-

      1.input an integer value n
      2.set fact to 1 and i to 1
      3.repeat step 4,5 until i less than or equal to n
      4.set fact to fact*i
      5.increment i by 1
      6.print fact

CODE:-

#include<stdio.h>
void main()
{
long int n, fact=1;
int i;
printf(“enter value for n”);
scanf(“%ld”,&n);
for(i=1;i<=n;i++)
      fact=fact *i ;
printf(“ factorial for the number %ld is %ld”,n,fact);
}


Input:- enter value for n 5
