Factorial program in C++ with call-by-reference

#include<iostream>
using namespace std;
void Factorial(int, int *);
int main()
{
    int Mynum, fact=1;
    cout<<"Enter the Mynumber: ";
    cin>>Mynum;
    Factorial(Mynum, &fact);
    cout<<"\nFactorial = "<<fact;
    cout<<endl;
    return 0;
}
void Factorial(int n, int *f)
{
    int i;
    for(i=n; i>=1; i--)
        *f = (*f)*i;
}

#include<iostream>

using namespace std;

void Factorial(int, int *);

int main()

{

int Mynum, fact=1;

cout<<"Enter the Mynumber: ";

cin>>Mynum;

Factorial(Mynum, &fact);

cout<<"\nFactorial = "<<fact;

cout<<endl;

return 0;

}

void Factorial(int n, int *f)

{

int i;

for(i=n; i>=1; i--)

*f = (*f)*i;

}

Output
