Our C⁺⁺ version *seems* simplest, but concepts behind >> and << are very complex and can be very dangerous (overriden operator). And in your code, I don't no if you know the difference, but std::endl is very very dangerous. It's not just equal to EOL but also flush the buffer. This bad shortcut lead to very poor i/o performances in most of applications, all outputs flushing continuously buffer instead just send EOL. All of those considered, C⁺⁺ code is the shortest but not the simplest =) - -- Aeris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJN/gziAAoJEK8zQvxDY4P9ChUH/0PevuUF1gmjz7VuPsc1+31L 3nNsrpg3TP343pz3jujbAhR8kKaTML44U/tX9TRtadGOfcfe1iurJv1FJ1qajmFn nSXlDVSOB9QeI1RTZ0w5pkZt85jJxw3Mdun8K3c9XVfNts9pIVowgLJZ7kQNt/CO y3RdMu0zq70DEFo8EEYuCfuo4F4OmdVQ0vk+EdFwo9vtBTgr6VPn2t+RLrOGZfUN CZGOYYFwezH4+8WYiMOKEtHIS2fKIDE46bID957jbvo3qLRA6058bi5cPU6zyzXz hdlzY59kdo/EstMG7Jo44qEpIqD0jzdgxUQVyZNWt7+8ghFnBOTcURlw/YiUa9k= =You3 -----END PGP SIGNATURE-----
