ЛАБОРАТОРНАЯ РАБОТА №3
«ОТНОШЕНИЕ НАСЛЕДОВАНИЕ»
по дисциплине «Объектно-ориентированное программирование»
Выполнили:
студент 2-го курса
дневного отделения
группы ИКПИ-92
Козлов Никита
Санкт-Петербург
2020
Постановка задачи
Дополнить систему, состоящую из двух классов “Класс №1” и “Класс №2”, которые были разработаны в лабораторной работе 2, новым классом “Класс №3”. Новый класс должен быть связан public наследованием с классом “Класс №2”. Класс “Класс №3” должен иметь одно поле, которое выбирается студентом самостоятельно. Для разрабатываемого класса написать конструкторы умолчания, с параметрами и конструктор копирования, деструктор, методы доступа и метод print(). Написать тестовую программу для проверки работоспособности разработанных классов.
