Please help me
Thank you so much

Best Answer

You've set the project to build as a Windows application, not a command line application. Change int main() to:

int CALLBACK WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR pCmdLine, int nCmdShow)

Or, change your project properties to be a command line application.
