std::make_ shared＜T＞/std::make_ Unique < T> and std:: shared_ ptr＜T＞/std::unique_ The difference and relation between PTR ＜ t ＞

(1)、std::make_shared<T> And std::make_unique<T> be relative to std::shared_ptr<T>/std::unique_ptr<T> Memory allocation only once
(2)、std::make_shared<T> And std::make_unique<T> Does not throw an exception ;

Besides ,std::make_shared<T> Is in C++11 Introduced in ;std::make_unique<T> stay C++14 Introduced in ;
