In this video I go over how references work in C++. I visually explain how a reference is essentially the same things as a pointer, and I go over the big benefits that you gain by using references instead of pointers. Next, I refactor our vector library to use references instead of copies and explain the benefits of doing so. Finally, I end with a challenge to incorporate everything we have learned so far and create a dynamic array.
