C program to Calculate Factorial of a Number using Recursion

C Implementation:

#include<stdio.h> #include<conio.h> int main() { long int num,fact; clrscr(); printf("enter the number to find factorial for it:"); scanf("%d",&num); printf("Factorial of %ld is %ld",num,fact(num)); return 0; getch(); } long int fact(num) { long int fact; while(num>0) fact=num*(fact(num-1)); return fact; }
