Type Specifiers

Type specifiers indicate the type of the object or function being declared. The fundamental data types are:

• Characters
• Floating-Point Variables
• Integer Variables
• Enumerations
• void Type

From these types, you can derive:

• Pointers
• Arrays
• Structures
• Unions
• Functions

The integral types are char, wchar_t (C++ only), and int of all sizes. Floating-point numbers can have types float, double, or long double. Integral and floating-point types are collectively called arithmetic types. In C++ only, you can also derive the following:

• References
• Classes
• Pointers to Members

In C++, enumerations are not an integral type, but they can be subject to integral promotion.

You can give names to both fundamental and derived types by using the typedef specifier.
