How do I debug recursion in C++?

How do I debug recursion in C++?

Debugging recursion can be tricky. Start by checking your base case to ensure it terminates correctly.

What if my base case is correct but it still doesn't work?

In that case, try adding print statements to track the function calls and see where it goes wrong.

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); }.

How can I visualize the recursion process?

You can use a call stack diagram to visualize how functions are called and returned during recursion.
