Join the Discord: https://discord.gg/4tHeAkxNg7 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. 0:00 In This Episode 0:30 Linked List Solution 2:49 How References Work 5:48 Vector Using References 10:29 Challenge: Dynamic Array --------------------------------------------------------------------- Website: https://ambrosiogabe.github.io/ Github: https://github.com/ambrosiogabe Here are some books I recommend if you want to learn about game engine development more thoroughly.
