Is complex number a data type in C language?

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
