SMART POINTERS in C++ (for beginners in 20 minutes)

A smart pointer is a container/wrapper for a raw pointer. In modern C++ smart pointers are defined in the std namespace in the memory header file.
One big advantage of smart pointers is that they are responsible for deleting the memory that they use, which means that they automatically deallocate the memory when they go out of scope.
There are three types of smart pointers in C++: unique pointer, shared pointer and weak pointer (std::unique_ptr, std::shared_ptr, std::weak_ptr)
