DataType in C

What is Data type in C?

Data type are storage representations and machine instructions to handls constants differ from machine to machine.the variety of data type available allow the programmer to select the type approriate the needs of the application as well as the machine.

There are three Classes of Data type

1.Primary Data type

2.Derived Data type

3.User-defined Datatype

In this topic we discussed in primary data type are available in c programming, all c compilers support five primary data type it is int,char,float,double,void the describe them are given in table.

Basic Data Types

Sr.No	Operators	Descriptions
01	char	-128 to 127
02	int	-32,768 to 32,767
03	float	3.4e-38 to 3.4e+e38
04	double	1.7e-308 to 1.7e+308

Integer Type

Integer are whole number with a range of values supported by a particular machine.generally integer occupy one word of storage.

Range and size of Integer Data Type

Sr.No	Type	Size	Range
01	Char or signed char	8	-128 to 127
02	Unsigned char	8	0 to 255
03	Int or signed int	16	-32.768 to 32,767
04	Unsigned int	16	0 to 65535
05	Short int or signed short int	8	-128 to 127
06	Unsigned short int	8	0 to 255
07	Long int or signed long int	32	-2,147,483,648 to 2,147,483,647
08	Unsigned long int	32	0 to 4,294,967,295
09	float	32	3.4E – 38 to 3.4E + 308
10	double	64	1.7E – 308 to 1.7E + 308
11	Long double	80	3.4E – 4932 to 1.1E + 4932

Floating Point Type

Floating point number are stored in 32 bit with 6 digits of precision. Floating defined in c by float keyword

For example float f1 = 10.01;

Void Type

The void type has no values.this is usually used to specify the type of functions.the type of a function is said to be void when it dose not return any value to the calling function.

Character Type

A single character can be defined as a character(char) type data.characters are usually stored in 8 bits(one byte) of internal storage.the qualifier signed or unsigned may be explicity applied to char while unsigned chars have values between 0 and 255,signed chars have values from -128 to 127.
