Debugging Software, Finding and Tracing Errors, Fixing Errors in Code

There will be times when you get an error message in code that you have developed, but you have no idea why you get the error message, or what causes the error message.

Here I explain how to trace the root cause of the problem and fix the error the correct way.

This lesson is about the concept of error tracing and can be applied to any software language or platform.
