Smart Pointers
Purpose
Smart pointer is an abstract data type that has all features of a standard pointer and additionally provides automatic garbage collection. Smart pointers facilitate the dynamic memory operations. Their main advantage is reducing memory leaks and bugs due to poor memory management.
