C Programming/Data Types

Data types in C refer to an extensive system used for declaring variables or functions of different types. The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted.

Types	Description
Basic Types	They are arithmetic types and are further classified into: (a) integer types and (b) floating-point types.
Enumerated types	They are again arithmetic types and they are used to define variables that can only assign certain discrete integer values throughout the program.
The type void	The type specifier void indicates that no value is available.
Derived types	They include (a) Pointer types, (b) Array types, (c) Structure types, (d) Union types and (e) Function types.
