Data type refers to the storage mode of data, including the size of occupied memory space, the range of values and the operations that can be performed. Numerical type refers to a data type that represents quantity and can be used for numerical operation.
Data types in C language can be divided into basic data types and construction data types, pointer types and empty types. Basic data types include integer, floating point, character and enumeration. Construction types include arrays, structures and * * * isomorphic types.

Unique features of c language:
1) universality. The operating range of C language directly determines its advantages and disadvantages. There are 34 kinds of operators in C language, so the operation range is incomparable to many other languages, and the expression forms of its operation results are also very rich.
In addition, C language contains many kinds of data structures such as character type and pointer type, so it can also cope with larger data structure operations.
2) simple. Nine control statements and 32 keywords are the basic features of C language, which makes C language widely applicable in computer application programming.
Not only can it be suitable for programmers to operate and improve their work efficiency, but it can also support advanced programming and avoid the complexity of language switching. ?
3), the structure is perfect. C language is a structured language, which can realize modular application by building modular units and has obvious advantages in system description. At the same time, this feature also enables it to adapt to a variety of different programming requirements and has high execution efficiency.
