In the previous chapter, we learned how to iterate over the elements of an array, using a for-loop . This allowed us to automate the coloring of our tiles rather than setting the color of each individually. Now we will learn to make choices in our code based on expressions that evaluate as either true or false. Combined with looping, this will allow us to generate complex tile patterns with very few lines of code.

Consider the pattern in Figure 4-1. There are eight rows and columns, and the tiles are ...
