- A program can be tested against a design.
- A piece of code can be matched to an outcome.
- A bug is an error in the coding of the program.
- Debugging is finding and fixing these errors in a program.

Only new programmers will have bugs in their programs.
Every programmer will need to correct errors and debug their code. Part of the process of programming is correcting mistakes made as you go along. Regluarly test your program does what it needs to as you go along.
