Data types in c refer to an extensive system used to declare different types of variables or functions. The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted.
Types of Data types:
- 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 specific 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.
