A data type is a set of data objects together with an appropriate set of operations for the object’s manipulation. Programs are usually written to perform certain actions and, in doing so, to manipulate some kind of data objects in certain ways. Thus, the possibilities of data representation by the features of a programming language are very important for a programmer. Programming languages partly differ from each other by the allowed types of data and the appropriate operations on data objects of these types.
