Today we'll look at switch statements, cases and their default code blocks. It's an interesting control structure. It's possible to program without using switch at all, but switch is often a clearer than a collection of if, else if and else.
The example at 7:10 is wrong. The output I've described is right but my reasoning is not. As pointed out by FullRock, the case 20 will run regardless of the value of "j". After a case executes, C++ does not check the conditions again and continues executing until it finds break.
