Question

So, like the title says I need to pull the min and max values from an array I’ve created that utilizes a random number generator to fill it. I get the feeling it’s probably the Math class of operators that I need to use (IE, the math.floor and math.ceiling) but if that’s so I’m not quite sure how to utilize them with the array. I suppose the bottom line is that I don’t quite understand how arrays work, even though I’ve already done a couple of assignments utilizing them. Here’s what I have so far (I have to display all values in the listbox and give average and min/max for this assignment)

 private void button1_Click(object sender, EventArgs e)
    {
    int SIZE = 10;
    int[] nummers = new int[SIZE];
    Random rand = new Random();
    int total = 0;

    for (int index = 0; index < nummers.Length; index++)
    {
        nummers[index] = rand.Next(1, 100);

    }
    foreach (int value in nummers)
    {
        total += value;
        listBox1.Items.Add(value);
    }
    total/= 10;
    label3.Text = total.ToString("d");

You can use Linq to make your life easier:

int minimum = numbers.Min();
int maximum = numbers.Max();

Old style:

modify the foreach to be like this:

int maximum = int.MinValue;
int minimum = int.MaxValue;
foreach (int value in nummers)
    {
        if (value < minimum) { minimum = value; }
        if (value > maximum) { maximum = value; }

        total += value;
        listBox1.Items.Add(value);
    }
