In the C programming language, data types are declarations for memory locations or variables that determine the characteristics of the data that may be stored and the methods (operations) of processing that are permitted involving them.
The C language provides basic arithmetic types, such as integer and real number types, and syntax to build array and compound types. Several headers in the C standard library contain definitions of support types, that have additional properties, such as providing storage with an exact size, independent of the implementation.[1][2]
Basic types Edit
The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short and long. The following table lists the permissible combinations to specify a large set of storage size-specific declarations.
