Reports

Decide whether to run the command line or the GUI based on the input parameters

Before run commandline，i call this function

#ifdef _WIN32
#    include <windows.h>
#    include <fcntl.h>
#    include <io.h>
#endif

void attachConsole()
{
#ifdef _WIN32
    if (AttachConsole(ATTACH_PARENT_PROCESS))
    {
        FILE* fDummy;
        freopen_s(&fDummy, "CONOUT$", "w", stdout);
        freopen_s(&fDummy, "CONOUT$", "w", stderr);
        freopen_s(&fDummy, "CONIN$", "r", stdin);
        std::ios::sync_with_stdio();
    }
#endif
}

But console output is flowing:

exit immediately after the program executes the command-line logic without any extra blank lines or repetitive output. but it go wrong!
