what is a type in C++?

Question

What all constructs(class,struct,union) classify as types in C++? Can anyone explain the rationale behind calling and qualifying certain C++ constructs as a 'type'.

Answer 1

$3.9/1 - "There are two kinds of types: fundamental types and compound types. Types describe objects (1.8), references (8.3.2), or functions (8.3.5). ]"

Fundamental types are char, int, bool and so on.

Compound types are arrays, enums, classes, references, unions etc
