.docxОтчёт по Лабораторной работе №2
По дисциплине «Объектно-ориентированное программирование»
Выполнила ст. гр. ИНФ-10-1
Михайлова Алексендра
Необходимо решить задание из предыдущей лабораторной работы в следующем виде:
Операции 1-3 необходимо реализовать в базовом классе;
Операции 4-7 необходимо реализовать в классе-наследнике;
Примечание: поскольку операция присваивания не наследуется, ее необходимо определить также в классе-наследнике.
