More Data Types

Abstract

So far, all data types of identifiers have been simple: they consist of one elementary type. The elementary types are

(char)	characters
(int)	integers
(float)	floating point

Chars and ints can be either signed or unsigned, and ints and floats can have modifiers short or long. A ‘long float’ is referred to as a ‘double’. Unless otherwise explicitly stated in a declaration, the default type is int.
