In computer programming, any item that the user can individually select and manipulate is called an object. This includes shapes and pictures that appear on a display screen as well as less tangible software entities.
Computer programming that defines not only the data type
of a data structure but also the types of operations/functions
that can be applied to the data structure. Thus, the data structure becomes an object that includes both data and functions. Programmers can create relationships between one object and another. For example, objects
can inherit characteristics from other objects.
