First off, I'm very sorry if this seems obvious. I'm sort of brand new to this whole field of software development
Second, and my question:
A co-worker of mine just asked me about two hours past how you choose whether to program a 32 bit program or a 64 bit program, or, in better words - how does the computer know whether it is 32 or 64 bit, and what influence does the dev have over that? I was unable to find the answers to this via Google, unfortunately, but may have been asking the wrong questions. Either way, I lacked an answer for him and now I'm curious myself.
