/*Тема 4: Да се състави програма на C++ за нуждите
на аптека, която поддържа следната информация:
Наименование на медикамент;
Производител;
Брой доставени;
Брой в наличност;
Срок на годност на медикамент;
Отпуска се с рецепта;
Дата на производство;
Партида;
Програмата извършва следните операции:
1.Създава масив от медикаменти;
2.Добавя нов медикамент;
3.Изтрива медикамент;
4.Извежда списък с имената на всички медикаменти
между две въведени дати на производство;
5.Извежда списък на медикаментите, чиито
производители започват с дадена дума;
6.Извежда списък на медикаментите, чиято
наличност е под 5 към момента на ревизията;
7.Извежда общ брой медикаменти в аптеката.*/
