Smart Pointers (Умни указатели)
Цел
Т.нар. умен указател e абстрактен тип данни, който има притежава всички функционалсти на стандартния указател и освен това осигурява автоматично изтриване (освобождаване на паметта). Умните указатели улесняват операциите, свързани с динамичното управление на паметта. Основното им предимство е намаляване на проблеми при работа с паметта и други проблеми, държащи се на лошо управление на стандартните указатели.
