To avoid problems with memory leaks and similar problems, the modern C++ programming language strongly discourages the use of raw (standard) pointers except for some cases. Instead, programs and programmers are encouraged to use smart pointers. - A smart pointer is a class template that is declared on the stack and initialized by using a pointer that points to the memory on heap. - The smart pointer will automatically delete the memory that the raw pointer points to. That is, we do not need to use the delete operator! - Inside of the destructor (smart pointer is a class template!) of the smart pointer there is a call to delete that releases the memory!
