int x = 20, y = 2;
do
{
    x -= x-2;
    y += 4;
    cout << x << "";
}while (y <= 16);
cout << ++x << "" << y << endl;

How do I managed such qns? Tks.

Please explain what does "qns" means? (Sorry, I'm not English)

Sorry. I am actually refering to the do... while loop code. I am figuring out how to solve it w/o using compiler.

If I explain your code that I get the following code:

1

int x = 20, y = 2;
do
{
    x = x - (x-2); // x gets 20 - (20 - 2)
    y = y + 4; // y is assigned value 6
    cout << x << "";
}while (y <= 16); // after first itaration x gets 2, y gets 6
x = x + 1;
cout << x << "" << y << endl;

You could track the iterations till the end.
