5. Templates and Generic Programming

Function templates, class templates, non-type template parameters, and a complete generic Stack<T> container.

6. The Standard Template Library

std::vector, std::map, iterators, and common algorithms like std::sort, std::find, and std::count_if.

7. Multithreading in C++

std::thread, data races, std::mutex and std::lock_guard, and a complete thread-safe bank account example.

8. C++ Interview Questions
