well,For each variable you have to attach some data type.
The data type defines:
1. the amount of storage allocated to variables.
2. the values that they can accept.
3. the operations that can be performed on variables.
C language data types, Primary data type, Integer Type, Floating Point Types, Void Type, Character Type, Size and Range of Data Types on 16 bit machine, derived data type, Declaration of Variables, User defined type declaration, Declaration of Storage Class, auto, static, extern, register, Defining Symbolic Constants, Declaring Variable as Constant and Volatile Variable
A C language programmer has to tell the system before-hand, the type of numbers or characters he is using in his program. These are data types. There are many data types in C language. A C programmer has to use appropriate data type as per his requirement.
C language data types can be broadly classified as
Primary data type
Derived data type
User-defined data type
