Types that store integer values, whose range is determined by the size of the data type and its signedness.

Floating-point types

Types that store real number values, whose range and precision is determined by the size of the data type.

Boolean types

Types that store boolean values.

Data Type Modifiers

Specifies additional characteristics of a standard or user-defined data type.

String types

Types that store or point to an array of characters.
