Master memory pointers, RAII, templates, STL containers, and modern C++20 standards.
Deep dive into C++: manual memory management, raw pointers vs smart pointers (std::unique_ptr, std::shared_ptr), RAII idioms, Object-Oriented design, Operator overloading, Templates, and the Standard Template Library (STL).
Preprocessing, compilation, assembly, linking, and the main() entry point.
Fundamental types, sizeof, type casting (static_cast), and memory alignment.
Address-of operator (&), dereference (*), raw pointers, references (Type&), and pointer arithmetic.
Stack allocation speed, dynamic heap allocation (new/delete), memory fragmentation, and leaks.
Resource Acquisition Is Initialization (RAII), std::unique_ptr, std::shared_ptr, and std::weak_ptr.
Class declaration, constructor initializer lists, destructors (~Class), and const member methods.
Lvalue vs Rvalue references (&&), std::move, copy constructor, move constructor, and Rule of 5.
Function templates, class templates, template specialization, and compile-time constexpr evaluation.
std::vector, std::unordered_map, std::sort, iterators, and <algorithm> header.
C++20 Concepts (type constraints), Ranges pipeline (| std::views), and Modules.
std::thread, std::mutex, lock_guard, std::atomic, lock-free programming, and CPU cache optimization.
