这个类是用来确保默认的C + +流（std::cin，std::cout等）正确的初始化和销毁。类跟踪多少个实例，它的创建和初始化C + +流的第一个实例时，构造以及刷新输出流的最后一个实例被销毁时.
Original:
This class is used to ensure that the default C++ streams (std::cin, std::cout, etc.) are properly initialized and destructed. The class tracks how many instances of it are created and initializes the C++ streams when the first instance is constructed as well as flushes the output streams when the last instance is destructed.
