On Visual Studio2017:

Create a single file C++ console program that solves a simple problem, where you demonstrate the use of Recursion in C++ programming. The program shall have at least one function that implements the base and recursive cases required when creating recursive functions. First, the program shall call the recursive function using its recursive branch (can iterate recursively several times here); lastly, end recursion with its base case as shown in zyBooks. Be creative and do not copy any of the zyBooks programs, your program shall be unique.
