The address of data[] is passed to the d[] array in the halve function. Because the address of d[] and data[] is the same, they both point to the same data. Changes made to d[] on line 14 modify the value of data[] in the setup block.

The draw function is not used because the calculation is made only once and nothing is drawn to the display window. Changing array data within a function without modifying the original array requires some additional lines of code. In the following example, the array is passed into the function as a parameter, a new array is made, the values from the original array are copied in the new array, changes are made to the new array, and finally the modified array is returned.

Working with arrays of objects is technically similar to working with arrays of other data types, but it opens the amazing possibility to create as many instances of a custom-designed class as desired.

Like all arrays, an array of objects is distinguished from a single object with brackets, the [ and ] characters. However, because each array element is an object, each must be created with the keyword new before it can be used. The steps for working with an array of objects are:.

These steps are translated into code in the following example. It uses the Ring class from page , so copy it over or retype it. This code creates a rings[] array to hold fifty Ring objects.

Space in memory for the rings[] array is allocated in setup and each Ring object is created. The first time a mouse button is pressed, the first Ring object is turned on and its x and y variables are assigned to the current values of the cursor.

Each time a mouse button is pressed, a new Ring is turned on and displayed in the subsequent trip through draw. When the final element in the array has been created, the program jumps back to the beginning of the array to assign new positions to earlier Rings. The next example requires the Spot class from page Unlike the prior example, variable values are generated within the setup and are passed into each array elements through the object's constructor.

Each element in the array starts with a unique set of x-coordinate, diameter, and speed values. Because the number of objects is dependent on the width of the display window, it is not possible to create the array until the program knows how wide it will be. Therefore, the array is declared outside of setup to make it global see p. Working with arrays of objects gives us the opportunity to access each object with a code structure called an enhanced for loop to simplify the code.

Unlike the for loop used previously in this chapter, the enhanced loop automatically goes through each element in an array one by one without needing to define the start and stop conditions. An enhanced loop is structured by stating the data type of the array elements, a variable name to assign to each element of the array, and the name of the array. For instance, the for loop in code is rewritten like this:.

Each object in the array is in turn assigned to the variable s , so the first time through the loop, the code s. The two statements inside the block run for each element of the array until the end of the array. This way of accessing each element in an array of objects is used for the remainder of the book.
