C++’s Predefined Streams
When a C++ program begins execution, four built-in streams are automatically opened. They are listed here:
| Stream | Meaning | Default Device |
|---|---|---|
| cin | Standard input | Keyboard |
| cout | Standard output | Screen |
| cerr | Standard error output | Screen |
| clog | Buffered version of cerr | Screen |
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.
