[Tutor] Generate 8 digit random number

[Alberto Troiano]

Hey Tutors

I saw a lot of responses...After analyze them I have resumed two approaches

1.- Generate a random number from 0 to 99999999 and fill this number with 
zeros (Almost everyone's approach)
2.- Generate 8 random numbers and join them (Pietro and someone else)

Which one of this is more randomic? I mean which one of these has lower 
chances to get duplicates?
Until now I'm using approach number 2.......Unless anyone has something 
against it...

Please, let me know what do you think about them

Thanks to all for the tremendous help (at least it is tremendous for me)

Alberto
