Crea un programa que solicite al usuario dos números enteros y luego intercambie los valores de ambas variables

#include <iostream>
using namespace std;

int main()
{
  int n1, n2, t;
    cout << "Enter first number: ";
    cin >> n1;
    cout << "Enter second number: ";
    cin >> n2;
    cout << "You entered: " << n1 << " and " << n2 << endl;
    t = n1;
    n1 = n2;
    n2 = t;
    cout << "After swapping: " << n1 << " and " << n2 << endl;
    return 0;
}
