    Design Guidelines

    Function Parameters & Return Values Fn Interfaces C++17

    cheat sheet about what function parameter types and return types to use
    • prefer specific types over general-purpose types
    • don't use getter/setter pairs for classes
    • use descriptive action names (verbs) for mutating member functions
    • avoid direct mutable access to class member variables from the outside
