C++: From Beginner to Advanced

Picture the bug that only appears in release builds, on someone else's machine, three weeks after you shipped. Nearly every one of those traces back to a single unanswered question: who owns this memory, and when does it go away? This path makes ownership the organising idea from week one, then builds the STL, templates and eventually cache-aware optimisation on top of that foundation.

Sample curriculum

An example outline for going from beginner to advanced in C++. Your generated course adapts this to your experience, target level and available study time.

  1. Memory, Pointers and Lifetime

    Stack against heap, what a pointer holds, references as non-null aliases, and the dangling-pointer and double-free mistakes this module exists to prevent.

  2. RAII and Smart Pointers

    Tying resource lifetime to object lifetime, unique_ptr against shared_ptr, and why modern C++ contains almost no raw new or delete.

  3. The Standard Library in Anger

    vector, map and unordered_map chosen by complexity guarantees, iterators, and the algorithms that replace most hand-written loops.

  4. Copy, Move and the Rule of Five

    What happens when an object is copied, rvalue references, move semantics, and letting the compiler generate the correct special members.

  5. Templates, Concepts and Compile-Time Work

    Function and class templates, constexpr, concepts for constraints that produce readable errors, and reading the error messages templates are notorious for.

  6. Performance and Undefined Behaviour

    Cache lines and data locality, structure-of-arrays layouts, profiling with perf, and running ASan and UBSan as routine practice rather than emergency measures.

C++ beginner-to-advanced questions

Which C++ standard should I be learning in one continuous path?

C++17 as the baseline with C++20 features where your toolchain supports them. Material written before C++11 teaches manual memory management that modern C++ actively avoids, and it is still widely circulated — one of the main reasons C++ advice is so inconsistent.

Do I still need raw pointers if smart pointers exist?

Yes. Smart pointers are built from them, and every existing codebase you join contains them. Understanding raw pointers is precisely what makes smart pointers feel obvious rather than magical.

What C++ interview questions come up at the advanced end?

The rule of five, move semantics, virtual destructors, what undefined behaviour actually permits the compiler to do, and cache-friendly data layout. All appear in the later modules as working practice.
