The MFC TRACE macro can output string characters to the VS debug output window during Debug, which is very convenient to track variables during debugging;
this macro cannot be used if it is not an MFC project or ATL project;
additional windows are included in the project .h this header file, and then use the OutputDebugString() function to have the same effect as the TRACE() macro;
#include "stdafx.h"
#include <windows.h>
int _tmain(int argc, _TCHAR* argv[])
{
//TRACE("dddddddd");
OutputDebugString(_T("AAAAAADDDDDDebug!!!"));
getchar();
return 0;
}
