Data types in C

Data types in C:
  Data type specifies the type of data that can be stored in variable.


 Basic Data Types in C:
1.Integer

2.Float

3.Double

4.Character

 Integer data type:

•           Represented by int.
•          e.g int a;
•          Int occupies 2 bytes.
•          16 bits.
•          216=65536
•          Range of integer(-32768-0-32767)

 Integer qualifiers:

Range of int can be changed using qualifiers.

•        Short int (2 bytes)
•        Long int (4 bytes)
•        Unsigned int (2 bytes, +ve values only)
•        (0-65535)
•        Unsigned long int (4 bytes, +ve values only)
•        (0-232-1)

Float/Real data type:

1.Represented by float.

  e.g 23.26,23.27,0.01 etc

2.4 bytes(32 bits)

 Double data type:

     1.Represented by double.

2.Used to store large real data values.

3.8 bytes

4.One qualifier

5.Long double (10 bytes)

Character data type:

  1. Represented by char 

   2.1 byte
