How do you make an algorithm that will return the number of elements in an array in C#?

Question

I already have some code that I think is going in the right direction, but need help filling in the gap. Please be aware that I cannot use array.Length here and I actually have to make a algorithm that will perform the same function as array.Length. Here is what I have so far:

    public static int size(int[] S, int n)
    {
        for (int i = 0; i < n; i++)
        {
            (S[i] 
        }
    }

Answer 1

This is a very silly assignment as C# arrays provide their length using the Array.Length property. I think you should make this clear in your delivery.

However, to stay within the rules try this:

int[] array = new int[10];
int count = 0;

// iterate all elements in the array
foreach(int item in array)
{
    count++;
}

// count will equal 10
return count;
