Write a C program with a user defined function myFactorial, that calculates the factorial of a number entered by the user. Return the calculated factorial and print it in the main function.

Written in C

#include <stdio.h>

int myFactorial(int n){

   int fact = 1;

   for (int k = 1; k<=n;k++)

   {

       fact*=k;

   }

   return fact;

}

int main() {

   int num;

   printf("Number: ");

   scanf("%d",&num);

   if(num>=0)    {

       printf("%d",myFactorial(num));

   }

   return 0;

}
