Undepricated gcc Hello World?

I tried to write the most basic hello world program I know of in c++ and I am getting deprication messages from gcc when I compile. Looking through the the documentation I have on line has merely lead to several levels of indirection. What am I supposed to use insted of ? And where do I find documentation on this which won't take me an hour to figure out how to use basic standard in and standard out? STH
