Now that we are nearing the realms of 64bit machines on peoples desktops i wondering what sort of effect this will have on C++ programming practices. Will the syntax need ammending etc? Will the topics and code i am learning at present be as applicable to these machines as it is to a 32bit machine?

Well, we'll probably need a medium int, but aside from that, I can't think of anything.

From what i read about 64 bit computing at its current state, the best way to use it is to emulate 2 processors, Slack has no support for 64 bit processing and most OS are "faking" support as well there is no call for it just yet, but intel are about to release a prosuction 64 bit processor so i think now we will see a bit more in this realm.

Note: there is a project called SLAMD64 which is slackware 64 but it is unoficial

Gentoo has a 64 bit port. works just fine on our dual 64 bit server.

didnt say it doesn't work but there are not many applications the utilise 64 bit processing yet

the list of the working ones grows each month (almost).

http://packages.gentoo.org/archs/amd64/

that's a listing of all the amd64 bit packages that they have ether written or ported over from 32 bit.

there is a list for ppc64 as well.

although lots of the packages are listed as testing or masked.

also, with the AMD Optrons, you can set your system up so that the Core OS is 64 and also have the ability to run 32 bit apps at the same time. It just means that you need to install the 64 bit libs and the 32 bit libs.....so if you have the disk space your golden.

Thanks for the input everyone, i just wanted to make sure that everthing i have learned so far will still be applicable. In hindsight when i read the posts then done some googling my question seems a little bit lame. Thank you all again.

not a problem, that's what we're here for!
