class Init;
Diese Klasse wird verwendet, um sicherzustellen, dass die Standard-C + +-Streams (std::cin, std::cout, etc.) korrekt initialisiert und zerstört. Die Klasse verfolgt, wie viele Instanzen von ihm erstellt und initialisiert die C + +-Streams, wenn die erste Instanz wird, sowie spült konstruiert die Output-Streams, wenn die letzte Instanz zerstört .

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.
