std::make_unique

Allocating memory and freeing it safely is hard if you are programming a very big application. In Modern C++ there are smart pointers that help avoid the mistake of incorrectly freeing the memory addressed by pointers. Smart pointers make it easier to define and manage pointers, they came with C++11. The most used types of C++ smart pointer areunique_ptr, auto_ptr, shared_ptr, and weak_ptr.
