Describe the process of debugging and troubleshooting code.

Answer:

  • Debugging Process:
    1. Reproduce the Issue: Identify the specific inputs or conditions that trigger the problem.
    2. Isolate the Problem: Narrow down the scope of the issue by isolating the problematic code or component.
    3. Identify the Root Cause: Analyze the code and identify potential causes of the issue, such as logical errors, exceptions, or unexpected behavior.
    4. Fix the Issue: Implement a solution to address the root cause of the problem.
    5. Test the Fix: Verify that the solution resolves the issue and does not introduce new problems.
    6. Document the Solution: Document the problem, its root cause, and the solution for future reference.
