[G++ n00b] getche() in G++ ?

[Stefan Kristensen]

Hello boys and girls.

I'm refreshing my C++ and to make it more interesting, I'm doing so on a 
FreeBSD box (I've grown up with Windoze - time to get mature).

My old school book has an example that uses getche(), which I understand 
is not C++ standard and is not supported by G++. Can anyone help me out 
and tell me what to use instead? And while we are at it: The same 
question for clrscr() ;-)

Thank you in advance
Stefan
