| cerr | An output stream for error messages |
| clog | An output stream to log program information |
| cin | An input stream that reads keyboard input from the console by default |
| cout | An output stream which writes output to the console by default |
| wcerr | The same as cerr but outputs wide char (wchar_t) data rather than char data |
| wclog | The same as clog but outputs wide char (wchar_t) data rather than char data |
| wcin | The same as cin but interprets each input character as a wide char (wchar_t) |
