However, it is possible to redirect one or more of the channels to file (or printer, or network, or elsewhere). That way, you can have normal output go to one place (eg. a file) and have any errors go to another place (eg. the screen). There’s actually very little difference between them.

Q: Does “cerr” has any more inner workings than printing “Oops, you entered an invalid age!” to the screen?

cout << "Oops, you entered an invalid age!" << endl;

and 

cerr << "Oops, you entered an invalid age!" << endl;

Thanks for pointing out the mistake. -Alex ] cout — an ostream_withassign class tied to the standard input

should read as

cout — an ostream_withassign object tied to the standard output
