Modern C++ Mastery: From Fundamentals to Full‑Stack Applications (C++23)
Unlock the Full Power of C++ C++ is the engine behind game engines, operating systems, financial systems, robotics, and high‑performance software. With the latest C++23 standard, the language has never been more expressive, safe, or enjoyable to write. Yet most courses either stop at basic syntax or drown you in theory without building anything real. This course is different. It takes you from absolute zero — assuming you’ve never written a line of code — all the way to designing, implementing, and shipping complete, modern applications with networking, databases, cross‑platform GUIs, and professional deployment workflows. Every concept is taught with working C++23 code, clear explanations, and hands‑on exercises. By the end, you won’t just “know C++”. You’ll be able to architect, debug, deploy, and distribute full‑stack C++ applications like a professional.
What You'll Learn
Programming Foundations — Understand algorithms, pseudocode, compilers, and the software development process.
C++ Core Language — Variables, control flow, functions, arrays, pointers, dynamic memory, and the Standard Template Library (STL).
Object‑Oriented Programming — Classes, inheritance, polymorphism, operator overloading, and design principles that scale.
Modern C++ (C++11 through C++23) — Smart pointers, lambdas, move semantics, std::expected, concepts, ranges, std::ranges::to, multidimensional subscript, and more.
Templates & Generic Programming — Write reusable code with function and class templates, constrained by C++20 concepts.
Robust Error Handling — Exceptions, RAII, and the new std::expected for safe, readable error management.
Networking — Build TCP clients and servers with Boost.Asio, asynchronous I/O, and C++20 coroutines.
Databases — Integrate SQLite and MySQL using both direct C APIs and C++ connectors; perform full CRUD operations.
GUI Development — Create polished, cross‑platform applications with Qt 6, including signals & slots, layouts, and model‑view architecture.
Deployment & Distribution — Package and ship your applications on Windows, macOS, and Linux. Static vs. dynamic linking, CMake install rules, creating installers (NSIS, Inno Setup, DMG), Docker containerisation, and CI/CD basics.
Real‑World Projects — Combine everything into capstone projects: a chatroom, a personal finance tracker, and a 2D game — and then deploy them.
