Hi Experts!

I wrote this program and wanted to ask if I did it correctly according to the following instructions:

Write a complete program to swap two integer variables using pointers. It must be a program that uses functions to do the task.

#include <iostream>
using namespace std;

void swap(int *i, int *j)
{
    int t;

    t=*i;
    *i=*j;
    *j=t;
}

int main()
{
    int a,b;

    a=5;
    b=10;
    cout << a <<" " << b << endl;
    swap(&a,&b);
    cout << a <<" " << b << endl;
      system ("pause");
      return 0;

}
