C Program With Recursion: Find Factorial Using Recursion in C Programming

It is a sample program example which demonstrate recursion in C programming. It is a factorial program with recursion. Accept number from the user and generate factorial of accepted number using recursion.

Program Code

#include"stdio.h"
#include"conio.h"
fact(int n);
void main()
{
 int n,r;
 clrscr();
 printf("************* Find Factorial of Number Using Recursion *************");
 printf("\n enter a number ");
 scanf("%d",&n);
 r=fact(n);
 printf("\n Factorial of %d is =  %2d\t",n,r);
 getch();
}

fact(int n)
{
 int f;
 if((n==0)||(n==1))
  return(1);
 else
  f=n*fact(n-1);
 return(f);
}

Output
