Can someone fully explain how recursion works in C++?

Question

I'm going through the C++ tutorial thoroughly to understand C++ completely. I'm learning about recursion right now. Does someone know what it is used for and how to use in game development? Please post some examples too.

// Will Appreciate It Very Much!!!
