Back to Basics: Declarations in C++
summary
Explains concrete rules rather than vague tips: why constexpr requires an initializer with examples of object definitions vs non-defining extern declarations, how T&& becomes a forwarding reference versus an rvalue reference and the deduction contexts that decide it, when to write typename for dependent nested types because of two‑phase template lookup, and the declarator operator precedence that makes pointer vs array vs function meanings. Examples compile or fail to show each rule.
