Data Types in C
A Data Types in C specifies the type of data that a variable can store such as integer, floating, character, etc.
There are the following data types in C language.
|Basic Data Type||int, char, float, double|
|Derived Data Type||array, pointer, structure, union|
|Enumeration Data Type||enum|
|Void Data Type||void|
Basic Data Types
The basic data types are integer-based and floating-point based. C language supports both signed and unsigned literals.
The memory size of the basic data types may change according to 32 or 64-bit operating system.
Let’s see the basic data types. Its size is given according to 32-bit architecture.
|Data Types||Memory Size||Range|
|char||1 byte||−128 to 127|
|signed char||1 byte||−128 to 127|
|unsigned char||1 byte||0 to 255|
|short||2 byte||−32,768 to 32,767|
|signed short||2 byte||−32,768 to 32,767|
|unsigned short||2 byte||0 to 65,535|
|int||2 byte||−32,768 to 32,767|
|signed int||2 byte||−32,768 to 32,767|
|unsigned int||2 byte||0 to 65,535|
|short int||2 byte||−32,768 to 32,767|
|signed short int||2 byte||−32,768 to 32,767|
|unsigned short int||2 byte||0 to 65,535|
|long int||4 byte||-2,147,483,648 to 2,147,483,647|
|signed long int||4 byte||-2,147,483,648 to 2,147,483,647|
|unsigned long int||4 byte||0 to 4,294,967,295|
|long double||10 byte|
