Write a program in C to find the factorial of a given number using pointers

#include <stdio.h>
void findFact(int, long int*);
int main()
{
        long int fact; //factorial of the number
        int num1;
scanf("%d",&num1); //The number is taken from test data

         findFact(num1, &fact);
         printf("The Factorial of %d is : %ld\n",num1, fact);
         return 0;
        }
void findFact(int n,long int *fact)
{
 *fact=1;
  int i;

for(i=1;i<=n;i++)
{
 *fact=*fact*i;
}
}
