BASIC DATA TYPES IN C

In this blog
Basic data types
A simple eg
small expl about void

Types of data type...

1.) Basic data  type

2.) Derived data type

3.) Enumerated data type

Basic data types

there are 5 basic data types in c 

Data type	keyword used	Size in bytes	Range	Format specifier
Character	char	1	-128 to 127	%c
Integer	int	4	-2,147,483,648 to 2,147,483,647	%d
Floating point	float	4	3.4E-38 to 3.4+38	%f
Double	double	8	1.7E-308 to 1.7+308	%lf
Valueless	void	0	Value less	~~

 

leaving this we are having many more data types with extensions :

1) unsigned        ( +ve  range only)

2) signed            ( both +ve and -ve range)

3) long                ( extended range )

4) short               ( short range)

so what is the use of this extensions , usage are based on requirement ,for eg  you want to store interger type of data but you dont need that much of space as that for basic integer so you can use short extension  in order to save some space. to read more go to  

so lets take an eg which would include  keyword used ,size in bytes ,Range and format specifier.

eg 

(if you dont know about the scanf and printf ,they are just used for scaning the value from the user and printing the value on screen respectively,dont wory i will discuss that in later)

(note : format specifier %d in this case, will change according to the datatype,and the value 2 in this case  should not be greater than range otherwise garbage value will gets diplayed)

(if you wanna know about the ranges then go to  )

explanation about void

void is data type mainly used for functions and pointer but not with variable (to know more about go to 

)

(we will discuss that whole concept late on because it is out of range of our topic)
