A C Program to find out factorial of a given number using recursion.

#include<conio.h>

#include<stdio.h>

int fact(int p);

void main()

{

            int n, ans;

            clrscr();

            printf(“Enter the number:”);

            scanf(“%d”,&n);

            ans = fact(n);

            printf(“Factorial of  a given number %d is %d”,n,ans);

            getch();

}

int fact(int p)

{

            if(p==1)

            {

            return 1;

            }

            else

            {

            return p*fact(p-1);

            }

}

OUTPUT:

Enter the number: 3

Factorial of  a given number 3 is 6
