Умные указатели
Цель
Умный указатель это шаблонный класс, который имеет все функции стандартного указателя и дополнительно обеспечивает автоматический сбор мусора. Умные указатели облегчают операции с динамической памятью. Их основным преимуществом является сокращение утечек памяти и ошибок из-за плохого управления памятью.
