And till this day, people writing command-line programs in an IDE like Visual Studio stumble on this fact, and the workaround is still the same: adding an stdin read or something like system("PAUSE") at the end, pausing the execution until the user hits Enter.

Best solution I've found:

    static void PressEnter(void) {
        if(IsDebuggerPresent()) {
            fprintf(stderr,"press enter\n");
            getchar();
        }
    }

Then from somewhere right near the top of main or whatever:

    atexit(&PressEnter);

You can throw in some isatty calls, or #ifdef _CONSOLE, or if(GetConsoleWindow()), etc., but the above pretty much always does the right thing.

Or you can flip the switch in the IDE itself to pause on exit.

Does Visual Studio have such an option? If so, where is it?
