The process of getting rid of all the errors (bugs) in your program is called debugging. There are many technigues for debugging programs, and they depend on the type of program and the tools available. It is beyond the scope of this book to discuss this subject. As a matter of fact, it is considered more an art than a science – as you dive deeper and deeper into programming, you’ll develop your own style and technique for debugging. But remember this: all programs have bugs, but good programs have only a few and they are well-hidden… |
