## Chapter 4. Types

## Fundamental Types

C++ has the following builtin types:

- char

- signed char

- unsigned char

- signed short

- signed int

- signed long

- unsigned short

- unsigned int

- unsigned long

- bool

- wchar_t

- float

- double

- long double

These fundamental types are always available, without having to include a header file. These types are exactly the same in either C++ or in C.

Specializing parts of the library on these types is prohibited: instead, use a POD.
