do while loop not looping

Question

I am having a problem with my do while loop.

do
{
    //this thing
}
while (n < 0 && n > 23);

when I run it every time I enter a number ether valid or invalid it ends my program.

Answer 1

This loop will run exactly once every time. Look at your test. It has to be true for the loop to execute more than once, but that will never happen. What number can be less than zero AND greater than 23 AT THE SAME TIME? ;-)
