stdout and stderr are different streams, even though they both refer to console output by default. Redirecting (piping) one of them (e.g. program.exe >out.txt) would not affect the other.
cout is linked with stdout while cerr is linked with stderr.

Generally, stdout should be used for actual program output, while all information and error messages should be printed to stderr, so that if the user redirects output to a file, information messages are still printed on the screen and not to the output file.
