Data types and variables

 Data type:-

In C programming, a data type is a classification that specifies the type of data that a variable can hold, the operations that can be performed on the data, and the amount of memory allocated for the data. The data type determines the range of values that a variable can store and the operations that can be performed on the variable.

Data types' example:-

     int,float,long int, double etc. are some examples of data types in C language.

 Types of 'Data type' in c language:-

Data types in the C language can be classified into the following categories:

1. Basic/Primitive Data Types:

   - Integer Types: char, int, short, long

   - Floating-Point Types: float, double, long double
   - Void Type: void
   - Boolean Type: _Bool

2. Derived Data Types:

   - Arrays: A collection of elements of the same type.

   - Pointers: Variables that store memory addresses.

   - Structures: User-defined data types that can contain multiple members of different types.

   - Unions: Similar to structures but only one member can be accessed at a time.

   - Enumerations: User-defined data types consisting of named integer constants.

3. User-Defined Data Types:

   - Typedef Names: Created using the typedef keyword to create new names for existing data types.

The basic/primitive data types are the fundamental building blocks of the C language and are used to store individual values. Derived data types are derived from the basic/primitive types and allow for more complex data structures and operations. User-defined data types allow programmers to create custom data types based on their specific needs.

Each data type has its own characteristics, such as size, range of values, and operations that can be performed on them. Choosing the appropriate data type is essential for efficient memory usage and proper manipulation of data in C programs.
