Return EXIT_SUCCESS not executing.

[Specula]

So I've got an assignment that is due in a few days and the code itself works perfectly. However, when it comes to exiting the program, EXIT_SUCCESS is being ignored. I know the code block with EXIT_SUCCESS in it is running because the cout statement above it displays, but the program will not exit without a hard Alt F4. Can anyone suggest how to make EXIT_SUCCESS do what it's supposed to? Sorry for the long code block.

Can anyone suggest how to make EXIT_SUCCESS do what it's supposed to?

EXIT_SUCCESS doesn't "do" anything, it's just a macro expanding to a value (usually 0), so

return EXIT_SUCCESS;

is no more magical than

return 0;.

but the program will not exit without a hard Alt F4.

Having to shut down your program by hand is a telltale sign of an infinite loop -- one of your while() loops never ends.

Sorry Smac, that doesn't do anything.

my bad

#include <cstdlib>

Thanks Catfish I figured as much, but I can't determine after 3 days of looking WHY the loop is repeating, hence why I'm posting here asking for help.

[Catfish3]

        levelRunning = true;
        while( levelRunning )
        {

            handleEvents();

            update();

            draw();

            if ( check4Win() )
            {

            }
            Sleep( 32 );
        }

Question, do you ever set levelRunning = false;?

[Specula]

No, I don't... I'll have to change that.
