    You wouldn't get 3, rand()%3 gives you a range between 0 and 2 but not including 3, add one to that and you get the range 1 to 3.

    Memory handler

    Okay, here's a custom memory handler I wrote for strings so that I won't have to make a bunch of calls to malloc. I probably won't use it, but it's good practice and might come in handy sometime. The...

    If you're going to use goto, at least jump forward in the code instead of backward. If you jump backward it makes the program harder to follow.
