    If you're going to try and get someone to do this (presumably for free?) for you, you shouldn't attack them with a giant wall of text. Break it up and/or add a TL;DR at the end.

    The OP is obviously talking about a sandbox game (e.g. Minecraft/Gmod) and not talking about computer security. Don't post useless definitions.

    Since you're having trouble with this, here's some "pseudo"code that might work:

    grade = getchar();
    if ( grade >= 90){

    You're overwriting the actual grade with a newline character every time. Instead, use:

    This is good advice, but remember, it doesn't have to be the same thing every time. Sometimes taking breaks from projects is very helpful when you're trying to solve bugs or add code.
