I ran the script as ventilator wrote it above and the first thing I came up with is that 'index' was an undeclared identifier. I think I've pretty much gotten around that by either declaring it as a variable outside of the function, or using 'int index' inside the function. However, the numbers I'm getting back are not right. I get a few integers between 1 and 192, but I'm also getting 0's and -999, 999. Could I get a more detailed explanation of how the code works so that I can figure out what's wrong with it? Thanks!

yes, sorry, i didn't test my script...

here is a corrected version:

Code:

void main()
{
	randomize();
	
	int n;
	int numbers[10];
	int array[192];
	for(n=0; n<192; n++) array[n] = n + 1;  // fill array with 1..192
	
	for(n=0; n<10; n++)
	{
	    int index = random((191-n)+1);
	    numbers[n] = array[index];
	    array[index] = array[191-n]; // remove the number from the array by replacing it with the last one in the array (the last one won't be accessed anymore)
	}
	
	printf("%d %d %d %d %d %d %d %d %d %d", numbers[0], numbers[1], numbers[2], numbers[3], numbers[4], numbers[5], numbers[6], numbers[7], numbers[8], numbers[9]);
	
}
