Can't run program in Debug mode (F5) - can without debug mode (Ctrl F5)

I guess we need to see some code. Please use Codeblocks when posting it.

What exactly it means to Compile in Debug mode can be modified. Could be this programm only works properly with the teachers personal Debub mode settings.

It is possible to define code to be only executed in Debug mode (or not in Debug mode), by letting the Preprocessor check if DEBUG is defined. But this option is very rarely used because it causes had to track problems like yours.
