Thread: Rand() not bieng very random

Sorry it's me again.

Anyway, the title pretty much explains it all. My program chooses five random numbers ranging from 1-5, (inclusive,) but it always chooses the same numbers in the same order. Is this normal? I ask simply because I wish to know the nature of rand(). I just can't see how any proccess a system performs can be random, as it has pre-set commands to determine these numbers. Can anyone explain the concept of random number generating? If you can please do as I am really lost.

Thanks for any replies.

Have you seeded rand() Generate random numbers?

No I hadn't. I wasn't sure how to generate a random seed, but I've just read the example you gave me, (Cheers for the link BTW,) and I'm going to try to use time as a seed like they did.

Thanks for the reply.

If you don't mean what I think you mean however then I'm confused.
