Special Member Functions in C++
summary
Explains exactly when the compiler emits or suppresses constructors, destructor, copy and move ops: declaring any constructor disables the default ctor, declaring copy or move ops affects the others (moves fall back to copies when absent), and requesting default or delete still counts as user-declared; the move/copy pair must be implemented together. Covers about eight constructor forms, demonstrates CPPInsights and Compiler Explorer to inspect generated code, recommends using sanitizers and static analyzers and compile-time tests, and advocates the rule of zero and rule of five and RAII patterns like RAII for resource safety.
