Wrong, plural type is not a data type in C language. In C language, data types can be divided into four categories: basic data types, constructed data types, pointer types, and null types. Among them, basic types: character type, integer type, real type (single precision type and double precision type), enumeration type; constructed type: array, structure, public body.

The data types in the following options do not belong to the C language yes( ).
A. Plural type
B． Logical type
C． Double precision type
D． Collection type
Correct answer: A
Answer analysis:
In C language, data types can be divided into basic data There are four categories: types, constructed data types, pointer types, and null types. Among them, basic types: character type, integer type, real type (single precision type and double precision type), enumeration type; construction type: array, structure, public body. The logical type in option B and the double precision type in C are both basic data types, the collection type in option D is a constructed type, and the complex type in option A is not a data type in the C language.
Extended information:
Data type:
The data type can be understood as an alias for a fixed memory size.
Data type is the model for creating variables.
In C language, data types refer to an extensive system for declaring variables or functions of different types. The type of a variable determines how much space the variable storage occupies and how the stored bit pattern is interpreted.
Array types and structure types are collectively called aggregate types. The type of a function refers to the type of the function's return value.
Integer types:
The following table lists details about the storage size and value range of the standard integer types:
| Type | Storage size | Value range |
|---|---|---|
| char | 1 byte | -128 to 127 or 0 to 255 |
| unsigned char | 1 byte | 0 to 255 |
| signed char | 1 byte | -128 to 127 |
| int | 2 or 4 bytes | -32,768 to 32,767 or -2,147,483,648 to 2,147,483,647 |
| unsigned int | 2 or 4 bytes | 0 to 65,535 or 0 to 4,294,967,295 |
| short | 2 bytes | -32,768 to 32,767 |
| unsigned short | 2 bytes | 0 to 65,535 |
| long | 4 bytes | -2,147,483,648 to 2,147,483,647 |
| unsigned long | 4 Bytes | 0 to 4,294,967,295 |
