Type Modifiers

Excepting type void, the basic data types might have several modifiers preceding them. It is used to alter the meaning of the base type to fit the requirement of various conditions more precisely. The list of modifiers is displays here: -

signed unsigned long

short

Modifiers can be applied to character and integer base types. Although, long can also be applied to double.
