/*
Создать класс money для работы с денежными суммами. число должно быть представлено двумы полями:
типа long для рублей и типа unsigned char для копеек. дробная часть(копейки) должна быть
отделена от целой части запятой. реализовать сложение, вычитание, деление сумм, деление суммы
на дробное число и операции сравнения.

Создать класс Goods. В классе должны быть представлены поля нименование, дата ояормления,
цена товара, кол-во единиц, номер накладной. реализовать методы изменения цены товара,
изменения кол-ва товара(уеньшение и увеличение), вичислекния стоимости. метод toString
должен выбавать в виде строки стоимость товара.
