Data Types

Data Types

• Data types specify the type of data we enter in our program.

• In C there are some predefined set of data types which are also called as primitive data types.

• Primitive data types are fundamental data types.

(1) integer type: These data types are used to store whole number. (i.e. the number without fraction).

Size and range of Integer type on 16-bit machine :

(2) float type : These are the data types used to store the real numbers (i.e. the numbers with fractional part).

Size and range of Integer type on 16-bit machine

(3) char type: This data type is used to store the character value.

(4) void type : Void data types mean no value. This data type is normally associated with a function that return no value.
