Заключение

Объектно-ориентированное программи́рование (ООП) - парадигма программирования, в которой основными концепциями являются понятия объектов и классов (либо, в менее известном варианте языков с прототипированием, - прототипов). Класс - это тип, описывающий устройство объектов. Понятие "класс" подразумевает некоторое поведение и способ представления. Понятие "объект" подразумевает нечто, что обладает определённым поведением и способом представления. Говорят, что объект - это экземпляр класса. Класс можно сравнить с чертежом, согласно которому создаются объекты. Обычно классы разрабатывают таким образом, чтобы их объекты соответствовали объектам предметной области.

Класс является описываемой на языке терминологии (пространства имён) исходного кода моделью ещё не существующей сущности, т. н. объекта. Объект - сущность в адресном пространстве вычислительной системы, появляющаяся при создании экземпляра класса (например, после запуска результатов компиляции (и линковки) исходного кода на выполнение).
