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.
CLASSIFICATION OF DATA TYPES IN C
- Basic Types
They are arithmetic types and are further classified into: (a) integer types and (b) floating-point types.
2. 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.
3. The type void
The type specifier void indicates that no value is available.
4. Derived types
They include (a) Pointer types, (b) Array types, © Structure types, (d) Union types and (e) Function types.
I. Integer type
The following table provides the details of standard integer types with their storage sizes and value ranges
II. Floating-Point Types
The following table provide the details of standard floating-point types with storage sizes and value ranges and their precision
