I've got a question which I didn't know how to answer, and where else to post it.
I program pretty much everyday and recently, my 5 year-old nephew has been sitting with me and asking questions (pretty simple ones really, but it's great that he's interested at such a young age!).
Yesterday as I was writing a very simple addition program for him to think about, he asked a question which I couldn't answer, so I thought I could ask the guys here if they can think of an answer that I could tell him.
I said that the computer takes the two variables and adds them together, so he asked "So, how do you know that the computer is right then?"
Can anyone think of a way in which I could explain to him without going in to too much detail, or giving the answer "it just is" please?
Thanks for the help,
