What are the limitations of recursion in C++?

Recursion in C++ can lead to stack overflow if the recursion depth exceeds the stack size. Additionally, it can be less efficient than iterative solutions due to overhead.

How can I avoid stack overflow in recursive functions?

To avoid stack overflow, you can use tail recursion optimization if the compiler supports it, or convert the recursive algorithm to an iterative one.

What is tail recursion?

Tail recursion is a special case of recursion where the recursive call is the last operation in the function. This allows some compilers to optimize the call stack.

Are there any specific examples of problems that are better solved iteratively?

Yes, problems like calculating Fibonacci numbers or factorials can be more efficiently solved using iterative methods to avoid the overhead of recursion.
