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.
