Anytime you do a rand you can get the same number more than once.So, when you generate your lotto number you need to check if you have already received that number, and if so, call rand again until you get a number you have not received.The easiest thing to do is add an array of 10 int as an edit mask. Initialize each element of this array to 0.You now map your rand%10 number, which must be between 0 and 9 to this 10 int array. If your rand%10 is 5, then look at the array5. If array5 is 0 you have not received a 5 so change array5 to 1.On the other and, if array5 is 1, then you have already received a 5 and you should call rand%10 again.
