chars, floats, or pointers, or arrays/structs of POD. The order in which class constructors and initializers for static variables are called is only partially specified in C++ and can even change from build extensions include GCC’s __attribute__, intrinsic functions such as __builtin_prefetch, designated initializers (e.g. Foo f = {.field = 3}), inline assembly, __COUNTER__, __PRETTY_FUNCTION__, compound provide useful features that do not exist in standard C++. For example, some people think that designated initializ- ers are more readable than standard C++ features like constructors. • Important performance

construct refers to the body of a class, method or constructor. Note that, by Section 4.8.3.1 on array initializers, any array initializer may optionally be treated as if it were a block-like construct. 4 4.1 appears: 1. Between consecutive members (or initializers) of a class: fields, construc- tors, methods, nested classes, static initializers, instance initializers. 7 • Exception: A blank line between two constants may optionally be formatted as if it were an array initializer (see Section 4.8.3.1 on array initializers). private enum Suit { CLUBS, HEARTS, SPADES, DIAMONDS } Since enum classes are classes, all
