The subscript operator

Note the use of the subscript operator [] in Listing 1 to declare the array.

The declaration syntax consists of:

• The type of data that will be stored in the array elements:  long
• The name by which the array will be accessed:  values
• The subscript operator, [], enclosing the number of elements in the array:  size

That's all there is to declaring an array in C++.

(Declaring an array in Java is a little more complicated because all arrays in Java are encapsulated in separate objects.)
