How do I debug recursive functions in C++?

Debugging recursive functions can be tricky. You can start by adding print statements to track the function's flow.

What should I look for in the print statements?

Look for the base case and ensure it's being reached. Also, check the values of parameters at each recursive call.

What if my function is running indefinitely?

If your function runs indefinitely, it likely means the base case is never met. Double-check your base case conditions.

Can you give me an example of a recursive function?

Sure! A classic example is the factorial function. Here's a simple implementation: `int factorial(int n) { return (n <= 1) ? 1 : n * factorial(n - 1); }
