I think 1 + rand() & 7 is wrong because this way all the random numbers above 7 are same as 7, ie I get 7 for newRand most of the time if you see what I mean.
I need good distribution of newRand.

1 + rand()%8 I have to think about, thanks.
Your idea of hardware random number generator is great, but since this project is for promotion and I'm not getting paid I have to do minimum effort, thats why my requirement is just to use rand function and no extra hardware.
