Fundamentals of Object-Oriented Programming - C++ - Recursion

The video tutorial introduces recursion as a method of executing code by having a function call itself, contrasting it with traditional looping. It demonstrates creating a program to calculate factorials using recursion, detailing the setup, function definition, and handling user input. The tutorial also addresses common errors and highlights the memory overhead associated with recursion, emphasizing the importance of understanding its implications in programming.

Describe the structure of a recursive function for calculating factorials.

What considerations should be made when using recursion in programming?
