🚀 "With great power comes great responsibilities" - said no one who uses pointers in C++ and seg-faulting your computer. In this video, we will demystify pointer, shared pointers, and references in C++, as well as giving exceptional advice on when you should use these constructs.

🖥️ Starting from the foundations, we explain how pointers in most languages are essentially just an offset to the virtual memory of your machine, and how you should dereference and delete pointers. We also look at how references are very similar to pointers, helping you avoid expensive copies with nicer-to-use semantics. Lastly, we will go over how std::unique_ptr, std::shared_ptr, and std::weak_ptr differ, and how you should use all of them!

👨‍💻 If there are any questions about pointers in C++, feel free to comment them 🔥

Looking forward to seeing how many of you have crashes your programs with a null pointer dereference👊
