I hope I can encourage you to think of yourself in a different light. You made a mistake. Grab the code you wrote, write some test data and see what it does.

I hope I can encourage you to think of yourself in a different light. You made a mistake. Grab the code you wrote, write some test data and see what it does. Fix it. It just takes practice -- over and over and over. Since you say that you will have CS degree "soon", I'll assume you are fairly new to programming. Making mistakes is something that you will do for your whole career. A mistake does not make you one kind of programmer over another. Even many mistakes does not. It just means more practice. Having the courage to post code off the top of your head in a world-wide forum, means you can have the courage to transcend where you are now. Keep trying to improve -- whatever it takes, and don't unnecessarily limit yourself.
