- 03.01Resource Acquisition Is Initialization (RAII) and Deterministic Cleanup4 min
Deconstruct the foundational C++ architectural idiom: RAII. Bind system resources (heap memory, POSIX file descriptors, mutex locks) to object lifetimes with guaranteed destructor invocation.
- 03.02Copy Constructors, Deep vs Shallow Copying, and Copy Assignment4 min
Analyze the hazards of shallow copying, implement deep-copy constructors, and master the exception-safe Copy-and-Swap idiom for copy assignment operators.
- 03.03Move Semantics, Rvalue References, and the Rule of Five4 min
Master modern C++ resource ownership: move constructors, move assignment operators, noexcept contracts, std::move casts, and the canonical Rule of Five.
- 03.04Guided Project 1: Industrial-Grade Dynamic String & Small String Optimization (SSO)Project4 min
Engineer a high-performance custom dynamic string class implementing the full Rule of Five, dynamic buffer reallocation, null-termination invariants, and Small String Optimization (SSO).
