C++’s Predefined Streams
The Standard C++ iostream library automatically opens the following streams:
| Stream | Meaning |
|---|---|
| cin | Standard input |
| cout | Standard output |
| cerr | Standard error output |
| clog | Buffered version of cerr |
| wcin | Wide-character version of cin |
| wcout | Wide-character version of cout |
| wcerr | Wide-character version of cerr |
| wclog | Wide-character version of clog |
By default, the standard streams are used to communicate with the console. However, in environments that support I/O redirection (such as DOS, UNIX, and Windows), the standard streams can be redirected to other devices or files.
