I'll show you how to allocate memory at runtime. Unlike stack variables that have fixed sizes, dynamic memory lets you create data structures that grow and shrink as your program runs.
You'll learn the difference between stack and heap memory, how to use new and delete, and the common mistakes like memory leaks and dangling pointers that trap beginners. By the end, you'll use smart pointers to manage memory automatically.
Modern C++ rarely needs raw new and delete because smart pointers handle cleanup for you.
