DATA TYPES
Variables contain the values on which the operations are performed. Every variable needs
to be assigned to a specific data type to make it accessible for the computer.
Data type identifies the type of data which the declared variable can hold. It helps the
computer to understand what operations need to be performed on the declared variables.
The common data types are:
Data Type Description Declaration Example
Integer (int) It represents whole numbers int x=4; 5, 10, 988
(zero, positive, negative value, not
the decimal value)/integer value).
Assigning non-integer value to
integer type variable returns error.
Integer type variable holds only a
single value.
Floating Point It represents real numbers with float x= 5.1; 4.65, 8.05, 10.1
Numbers (float) decimal values or fractions. double x=
Another type of floating-point 9.99*8.888
number is 'double' data type, to
store even bigger values.
Character (char) It holds a single letter. (e.g., a.b.c.) char x='y'; 90 (in ASCII, 90
The syntax of declaring a character is a upper case
type variable is specific to the 'Z')
programing language.
It is the smallest data type by size.
Assigning a non-character type
value to a character type variable
returns error.
