Program 

#include <stdio.h> 

#include<conio.h>

long int factorial(int n)

{  

if(n==1)    return 1;

return n*factorial(n-1);

}

int main()

{

int num;

long int fact=0;     

printf("Enter an integer number: ");

scanf("%d",&num);     

fact=factorial(num);

printf("Factorial of %d is = %ld",num,fact);

printf("\n");  

return 0;

}

 

Output:-

Enter an integer number: 5

Factorial of 5 is = 120
