C++ Intermediate

A pointer is a variable that stores a memory address. Learn how pointers work, pointer arithmetic, and null pointers.

Understand the difference between stack memory (fast, automatic) and heap memory (dynamic allocation), and when to use each.

Visual map of C++ memory segments: text (code), data (globals), heap (dynamic), and stack (locals).

How Resource Acquisition Is Initialization prevents memory leaks, and how unique_ptr, shared_ptr, and weak_ptr manage ownership.

std::vector, std::map, std::unordered_map, std::set, iterators, and the algorithm functions that operate on them.

Follow the call stack as main calls a function, a local variable is created, and the stack frame is pushed and popped.

A function call transfers control while preserving enough state for the caller to resume.

Follow the key state changes and boundary checks involved in what a function call places in a stack frame.

An interactive concept flow for what a function call places in a stack frame, from its assumptions through the main operation and boundary checks.
