Write a program in C to display the factorial value of n.

 // factorial-of-n.c

#include <stdio.h>

#include <conio.h>

int main()

{

int n, i;

unsigned long long int fact=1;

printf("Enter a natural number: "); // between 0 - 65

scanf("%d", &n);

for (i = 1; i <= n; i++)

{

fact *= i;

}

printf("Factorial of %d is %llu \n", n, fact);

getch();

return 0;

}
