How to implement a recursive function in C++?

I am trying to implement a recursive function in my C++ code, but I am not sure how to approach it. Can anyone provide guidance on how to correctly write a recursive function in C++?

To implement a recursive function in C++, you need to make sure that your function calls itself within the function body. This allows for repeated execution with different parameters until the base case is reached. When calling the function, make sure to provide appropriate parameters to ensure the function will eventually reach the base case. Also, make sure to correctly handle the base case to prevent an infinite loop.

When writing a recursive function in C++, you must make sure to have a termination condition, which will eventually end the function calls. This can be achieved by using an if statement to check if the input parameters meet a certain criteria. Additionally, pay attention to the variable scope and properly use return values.

In C++, a recursive function can be implemented by breaking down the problem into smaller sub-problems, until a base case is reached. To improve efficiency, it is important to make use of memoization to store previously computed results. This will help reduce the number of function calls and improve the overall efficiency of the recursive function.
