32bit to 64bit diffrence in code?

[degus]

iam new to coding and got 2 comuters, 1st i an Acer Aspire laptop with a amd 32 proccessor, 2nd Hp Amd athlon 64bit proccessor. I have to run 64 bit linux on my Hp computer since it has the famous X-FI sound card.

iam gonna start learn to code in C within a few days and need to know te diffrence in 32 bit coding and 64bit coding since i will be working on 2 diffrent systems.. please add some code examples..

Your coding on both systems should be quite similar. Just be aware as you code that pointers (and possibly other data types) aren't necessarily 4 bytes long.

For more detailed discussions on the differences, google this:

difference 32 64

Some of the search results will be quite irrelevant, but others will be helpful, I'm sure.
