CString to std :: cout

How to print CString to console? Tried this code but got something like a pointer.

int _tmain(int argc, _TCHAR* argv[])

Use the following:

std::wcout << a.GetString();

Use wcout to print CString to console:

CString cs("Hello");
wcout << (const wchar_t*) cs << endl;

My apologies. I didn't finish and was interrupted. Obviously you need to convert to temporary CStringA (otherwise it is wide format ie wcout). I didn't get it until I read your post (again):

std::ostream& operator << ( std::ostream& os, const CString& str )
{
  if( str.GetLength() > 0 )  //GetLength???
  {
    os << CStringA( str ).GetString();
  }
  return os;
}

You could, as suggested, just use wcout:

std::ostream& operator << ( std::wostream& os, const CString& str )
{
  if( str.GetLength() > 0 )  //GetLength???
  {
    os << CStringA( str ).GetString();
  }
  return os;
}

Then use like this:

std::wcout << str << std::endl;
