Q - How do you know whether a computer program has a bug?
A - The program you are trying to run wouldn't be working properly if it had a bug. When a bug is in the program it could be running slower, acting up, or perhaps just running different than normal. A bug is what takes a program and affects the mechanics of how that program runs. When you take a bug and the properly working program and put them together, what makes up that program is confused as to what to follow and therefore affects the way it works.
