Back to Basics: Functions in C++
Talkat CppCon 2023 · on Monday, 2023-10-02· at 14:00· Maple 3/4/5, 6700 North Gaylord Rockies Boulevard·
summary
Walks from simple signatures to machine code: uses compiler explorer (godbolt) and objdump to show call instructions, labels and that functions have addresses; demonstrates taking addresses, C-style pointers, std::function, arrays of operations, and higher‑order functions; covers lambdas/functors, capturing state, function composition, namespaces, headers/pragma once, modules, and grouping in classes with virtual/static/member/operator overloading; explains pass‑by‑value vs reference, span for ptr+len, and constexpr/consteval compile-time evaluation; slides and code live on the GitHub link.
