List initialization since C 11 cppreference
List initialization since C 11 cppreference Otherwise if T is a specialization of std initializer list the T object is direct initialized or copy initialized depending on context from a prvalue of the same type initialized from until C 17 the braced init list Otherwise the constructors of T are considered in two phases All constructors that take std initializer list as the only argument or as the first argument if the
ESP32 ESP8266 Arduino Initializer List Techtutorialsx
The effects of list initialization of an object of type T are If the braced init list is empty and T is a class type with a default constructor value initialization is performed Otherwise if T is an aggregate type aggregate initialization is performed Otherwise if T is a specialization of std initializer list a new std initializer list object of the same type is constructed and List initialization cppreference University of Chicago. Explanation Constructors have no names and cannot be called directly They are invoked when initialization takes place and they are selected according to the rules of initialization The constructors without explicit specifier are converting constructors The constructors with a constexpr specifier make their type a LiteralType Understanding Initialization Lists in C By Alex Allain Understanding the Start of an Object s Lifetime In C whenever an object of a class is created its constructor is called But that s not all its parent class constructor is called as are the constructors for all objects that belong to the class
