Identifying Common Code Smells (In C++)
summary
Examines concrete C++ smells and fixes with real examples: a 260-line main refactored into helpers and small classes, long conditionals turned into named predicates and collision helper functions, pointer cleanup replaced by RAII and smart pointers, missing const qualifiers and Rule-of-Five issues highlighted in vendor drivers. Recommends tools and measurements: use compilers and optimizers, run profilers, UB/memory sanitizers and IDE refactorings before hand-rolling changes. Coverage includes SFML, libsass and hardware-driver examples so the payoff and tradeoffs are visible.
