Recursion and Recursive Functions in C++. Recursive function is a function that calls itself. In this video we will go over how to traverse through a vector in a recursive function. First we would need a base case which is usually when the index reaches out of bounds (index == size). Then we need to create a recursive step which is the index. With each recursive call, we pass index + 1, which increments the index towards the base case (index == size).
