当入口函数不是main，是_tWinMain 等windows 相关的入口函数时候
这样就可用std::cout 来输出
AllocConsole();
freopen("CONIN$", "r", stdin);
freopen("CONOUT$", "w", stdout);
freopen("CONOUT$", "w", stderr);
AppDelegate app;
Application::getInstance()->run();
FreeConsole();- AllocConsole();
- freopen("CONIN$", "r", stdin);
- freopen("CONOUT$", "w", stdout);
- freopen("CONOUT$", "w", stderr);
- AppDelegate app;
- Application::getInstance()->run();
- FreeConsole();
AllocConsole();
freopen("CONIN$", "r", stdin);
freopen("CONOUT$", "w", stdout);
freopen("CONOUT$", "w", stderr);
AppDelegate app;
Application::getInstance()->run();
FreeConsole();
