#include<stdio.h>
#include<conio.h>
int factf(int);
void main()
 {
    int a, fact;
      printf("enter a number to find its factorial:- ");
      scanf("%d",&a);
      fact=factf(a);
      printf("Factorial is %d",fact);
      getche();
   }
int factf(int x)
 {
    int y=1;
    if(x !=0)
       y=x*factf(x-1);
      return(y);
   }

Recursive function is that function that falls it self. We should set certain conditions if not the program will be of infinite loop.
