Задали такой проект ..... допустим у меня 3 магазина. каждый продает оргтехнику ..... создал класс shop потом методом hook shopA shopB shopC и к каждому предмету для продажи создал cur. В Cur такие функции как модель, цена, товаров продано, описание и доход с товара. так вот как сделать что бы в cur посчитать цену умноженную на кол-во товаров и потом отразить в доход от одельного предмета, потом, от отдельного магазина и , от всех магазинах вместе взятых ? (Первый курс тока закончил не судите строго) Вот мой код: | Код |
