How to do it...

The following is a list of typical operations you need to be aware of for working with unique_ptr:

• Use the available overloaded constructors to create an unique_ptr that manages objects or an array of objects through a pointer. The default constructor creates a pointer that does not manage any object:

        std::unique_ptr<int>   pnull;        std::unique_ptr<int>   pi(new int(42));        std::unique_ptr<int[]> pa(new int[3]{ 1,2,3 });        std::unique_ptr<foo>   pf(new foo(42, 42.0, "42"));

• Alternatively, use the std::make_unique() function template, available in C++14, to create unique_ptr objects:

        std::unique_ptr<int>   pi = std::make_unique<int>(42);        std::unique_ptr<int[]> pa = std::make_unique<int[]>(3); std::unique_ptr<foo> pf = std::make_unique<foo>(42, ...
