what is debugging?

In this video you will learn about debugging and how to process it.

It is the process of detecting and removing of existing and potential errors (also called as ‘bugs’) in a software code that can cause it to behave unexpectedly or crash.

A user of a program must know how to fix the problem as knowledge about problem analysis is expected. When the bug is fixed, then the software is ready to use. Debugging tools (called debuggers) are used to identify coding errors at various development stages.

The following are the Debugging Process:

1 .Reproduce the problem.

2. Describe the bug. Try to get as much input from the user to get the exact reason.

3. Capture the program snapshot when the bug appears. Try to get all the variable values and states of the program at that time.

4. Analyze the snapshot based on the state and action. Based on that try to find the cause of the bug.

5. Fix the existing bug, but also check that any new bug does not occur.
