Back To Basics: The Special Member Functions
summary
Covers the six special member functions (default ctor, dtor, copy/move ctor and assignment) with concrete rules when the compiler generates or omits them, what the default implementations actually do (member-wise copy/move, no cleanup of raw pointers), and common surprises: value vs default initialization, noexcept from =default, self-assignment bugs, and when move is suppressed. Shows fixes and tools: Rule of 0, use of unique_ptr/shared_ptr, the temporary swap idiom and using =default / =delete to express intent.
