An array stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.

Module Module1

            num(i) = i + 100
        Next i
        For o = 0 To 10
            Console.WriteLine("index ({0}) = {1}", o, num(o))
        Next o
