Ans:- Data type defines a range of values that a variable can store. It also includes set of operations that are performed on different data types.

There is predefined data type as:

Integers are the whole numbers that allow only the numbers to be written without any decimal points.

The real numbers are treated as floating point numbers that can have decimals as well with the non-decimal digits.

Boolean data types define only the two values either it is true or false. In programming it can be used when there is a decision need to be made between the two entities.

Char data type allows the single character to be written in an ordered form with the ordered character set.
