Named Constants
	v In programming we often need to use various constants, e.g. RGB combinations, the number of steps to take in a squiral, etc. v It is good programming practice to give names to these, rather than embedding the constants in your code. v Advantages: o Putting them at the beginning of your code makes it easier to find and change them. o If you use the constant in several places and want to change it, there’s just one place to change.
