Comparing in Array
<p>There is something wrong with my code.  I am teaching myself c# and one of the challenges in this chapter was to prompt the user for 10 numbers, store them in an array, than ask for 1 additional number.  Then the program would say whether the additional number matched one of the numbers in the array.  Now what I have below does work, but only if I enter in a comparison number that is less than 10 which is the size of the array.</p>

<p>I'm not sure how to fix it.  I am not sure how to do the comparison.  I tried a FOR loop first which kind of worked, but ran through the loop and displayed the comparison against all 10 numbers so you would get 9 lines of No! and 1 line of Yes!.  I put in a break; which stopped it counting all 10 but if I entered the number 5 for comparison, then I would get 4 lines of No! and 1 of Yes!.  The below has been the only way I could get it to work reliably but only as long as the number isn't out of the bounds of the array.</p>

<p>I can see why I get the error when the number is above 10, I just don't know what to use to compare it but still allow the user to enter in any valid integer.  Any assistance would be great!</p>

<pre><code>        int[] myNum = new int[10];
        Console.WriteLine("Starting program ...");
        Console.WriteLine("Please enter 10 numbers.");

        for (int i = 0; i &lt;= 9; ++i)
        {
            Console.Write("Number {0}: ", i + 1);
            myNum[i] = Int32.Parse(Console.ReadLine());
        }

        Console.WriteLine("Thank you.  You entered the numbers ");
        foreach (int i in myNum)
        {
            Console.Write("{0} ", i);
        }

        Console.WriteLine("");
        Console.Write("Please enter 1 additional number: ");
        int myChoice = Int32.Parse(Console.ReadLine());
        Console.WriteLine("Thank you.  You entered the number {0}.", myChoice);

        int compareArray = myNum[myChoice - 1];

        if (compareArray == myChoice)
        {
            Console.WriteLine("Yes!  The number {0} is equal to one of the numbers you previously entered.", myChoice);
        }
        else
        {
            Console.WriteLine("No!  The number {0} is not equal to any of the entered numbers.", myChoice);
        }

        Console.WriteLine("End program ...");

        Console.ReadLine();
