#include <iostream>
using namespace std;


int main()
{
    int a = 5, b = 10, temp;


    cout << "Before swapping." << endl;
    cout << "a = " << a << ", b = " << b << endl;


    temp = a;
    a = b;
    b = temp;


    cout << "\nAfter swapping." << endl;
    cout << "a = " << a << ", b = " << b << endl;


    return 0;
}

Output

Before swapping.
a = 5, b = 10

After swapping.
a = 10, b = 5
