Data Type:-Data type is used to define a variable in a program(before it is used).

C has 4 type of 'data type' namely-

1)Primary Data type.
2)Secondary Data type.
3)User defined Data type.
4)Empty Data type.

1)Primary Data Type:-Primary data type also called as basic data type and built in data type.Some primary data type are-int,char,float,long etc.

Data type	Range	bytes	Format String
int	-32768 to +32767	2	%d
char	-128 to +127	1	%c
Float	-3.4e38 to +3.4e38	4	%f
unsigned int	0 to +65535	2	%u
unsigned char	0 to +255	1	%c
long int	-214783648 to +214783647	4	%ld
long unsigned int	0 to +4294967295	4	%lu
double	-1.7e308 to +1.7e308	8	%lf
long double	-1.7e4932 to +1.7e4932	10	%LF

2)Derived Data type:-The definition of derived data type is quite simple "those data type which are derived from the primary data type are called Derived Data type"

Example-union,array,structure,pointer,enum etc.

3)User-Defined Data type:-Those data-type which are defined by users.
Example:- typedef<basic data type><new data type>
Like:-typedef float fl;

4)Empty Data type:-Empty data types are those data types which return null value.
Example:-Void.
