Learning to debug one's own code is an essential skill. Sadly, one that apparently few college courses teach. Silly if you ask me.

Placing breakpoints and walking through the code line by line allows you to actually WATCH it execute.

Visualizing what your code does will let you see why it behaves the way it does.

It would be well worth your time to do the tutorials on FAQ 2. A couple hours learning this skill will save you hundreds of hours of confusion in one project alone.

See FAQ # 2. (Click the SHOW button below)
