What are some tips for debugging recursion in C++?

Debugging recursion can be tricky. Here are some tips: 1. Use print statements to track function calls. 2. Check base cases to ensure they are correct. 3. Visualize the call stack to understand the flow. 4. Use a debugger to step through the code.

How can I visualize the call stack?

You can visualize the call stack by using a debugger tool in your IDE. Set breakpoints in your recursive function and observe how the stack grows with each call.

What if my recursion doesn't seem to terminate?

If your recursion doesn't terminate, check if your base case is reachable. Ensure that the recursive calls are moving towards the base case.

Are there any common mistakes to avoid?

Yes, common mistakes include forgetting to update parameters in recursive calls, not defining a proper base case, and excessive memory usage leading to stack overflow.
