What are the data types in c language

C language data types

The C language is a statically typed language, which means that the types of variables must be declared at compile time. The basic data types available in C language are:

Integer type:

• char: one byte
• short int or short: two bytes
• int: four bytes (32 bits)
• long int or long: eight bytes (64 bits)

##Floating point type:

• float: four bytes (single precision)
• double: eight bytes (double precision)

Empty type:

• void: Indicates no type

Character type:

• char: Single character

Boolean type:

• _Bool : Boolean value (true or false)

Others:

##size_t
• : Size type (depends on the system)
ptrdiff_t
• : Pointer difference type (depends on the system)

Integer type

The integer type is used to store integer values ​​(no decimal part). The size of the type depends on the system architecture.

Floating point type

The floating point type is used to store approximate values ​​with decimal parts. The

float

type represents single-precision values, while the double type represents double-precision values.

Empty type

void

Type means there is no type. It is used to return no value (void functions) or as a generic pointer type.

Character type

char

type is used to store a single character. It is also used in C language as a primitive type for strings.

Boolean type

The Boolean type is used to store Boolean values ​​(

true

or false). It can use conditional statements and logical operators.
