• STL Deep Dive — containers, iterators, algorithms, ranges

• Error Handling — exceptions, std::expected, undefined behavior

• Concurrency — multithreading, coroutines, atomics & the memory model

• Modern C++ — C++17, C++20 and C++23 features explained

• Performance — cache locality, copy elision, profiling, compiler optimizations

• Systems Programming — bit manipulation, memory layout, interfacing with C

• Tooling — design patterns, testing, debugging, CMake, linking & ABI

Every C++ lesson includes clear explanations, real code examples with syntax highlighting, and key points to remember.
