Calculate Factorial Using recursive function

Hello Here is a program for Reading a number from user and print the factorial of that number using recursive function.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

#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.
