What are some effective debugging methodologies?

There are several effective debugging methodologies, including:

1. Print Debugging: Inserting print statements to track variable values.
2. Interactive Debugging: Using a debugger tool to step through code.
3. Rubber Duck Debugging: Explaining your code to someone else to find issues.
4. Unit Testing: Writing tests to catch bugs early.
5. Log Analysis: Reviewing logs to identify errors.

Can you explain how interactive debugging works?

Interactive debugging allows you to pause the execution of your program and inspect the current state. You can step through the code line by line, examine variable values, and modify them on the fly to see how changes affect the program.

What tools are commonly used for interactive debugging?

Common tools for interactive debugging include:

• GDB for C/C++ programs.
• PDB for Python.
• Chrome DevTools for JavaScript.
• Visual Studio Debugger for .NET applications.

How does rubber duck debugging help in finding bugs?

Rubber duck debugging helps by forcing you to articulate your thought process. Explaining your code out loud can reveal logical errors or gaps in your understanding that you might not notice when just reading the code.
