class Init;
Essa classe é usada para garantir que o padrão C + + correntes (std::cin, std::cout, etc) são devidamente inicializado e destruído. A classe acompanha quantas instâncias de que são criados e inicializa o C + + correntes quando a primeira instância é construída, bem como ondas de os fluxos de saída quando a última instância é destruída.
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.
