C++ iostream objects
The <iostream> library provides objects which can read user input and output data to the console or to a file.
A list of all iostream objects can be found in the table below.
| Object | Description |
|---|---|
| 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 ) |
| wcout | The same as cout but outputs wide char ( wchar_t ) data rather than char data |
