Generally speaking, a debugger is thought of as a tool to use after a problem is encountered, when its cause is not obvious. Although a good debugger is the best tool for diagnosing problems and defects in software products, their use in the code writing phase is often overlooked.

At the end of the article, I will discuss some of the basic requirements that a debugger must meet in order to apply this technique.
