Question

I want this loop to decrement from the value I set it to from 10 to 0. Why does it keep going forever?

int lengthString = 10;

for (int j = lengthString; lengthString > 0; j--)
{
    cout << j;
}

Answer 1

Change to

 for (int j = lengthString; j > 0; j--)

lengthString doesn’t change in your loop.

Also, you might want to verify that lengthString is greater than 0 (in your real code) if you declare j as an int, because if j is initialized to a negative number, the loop will run “forever” (until it overflows and gets decreased to 0 again, that is).
