Can't you just create an array of 5000 ints

Help with Code Tags

(Toggle Plain Text)

for (int i =0; i< 5000; i++ )
{
   array[i] =i;
}

Then shuffle them around. So you would be picking two random index positions and swapping them. Do this say a couple of hundred times.

Then just print out the first 200 elements and you will get 200 random elements with no repeats in a number range from 0 - 5000.

... the hat of 'is this a cat in a hat?'
