When should you use break or continue in a loop?
	When it makes your code easier to read/maintain/understand as opposed to working it into the boolean condition for the loop.
	The danger of using break or continue in a large loop is that it becomes 'hidden' and people might not realize that something inside the loop affects its control flow.

What are the advantages/disadvantages of switch...case?
	+ The expression is only checked once in one place, and would only need to changed in one place
	- You have to keep putting 'break;' at the end of each case if you don't want the case to "fall through".  If you forget, it still compiles.
	+ You can exploit the fall-through behavior, as follows:
		for(int days = 1; days <= 12; days++) {
			switch (days) {
				case 12: ...three french hens...
				...
				case 3: ...three french hens...
				case 2: ...two turtle doves...
				case 1: ...partridge in a pear tree...
			}
		}
