Print factorial of a given number using recursive function.

#include<stdio.h>

#include<conio.h>

int fact(int);

void  main(){

  int num,f;

  clrscr();

  printf("\nEnter a number: ");

  scanf("%d",&num);

  f=fact(num);

  printf("\nFactorial of %d is: %d",num,f);

  getch();

}

int fact(int n){

   if(n==1)

       return 1;

   else

       return(n*fact(n-1));

 }

Output:-

Enter a number: 6

Factorial of 6 is: 720
