14/*We find that the output is POSITIVE, even though 7 is odd and so 
15nothing should be printed. This code doesn't work as desired because 
16we only want to test for positivity when we already know that the 
17number is even. We can enable this behavior by putting the second 
18conditional inside the first.*/

31/*Notice that when we put one conditional inside another, the body of
32the nested conditional is indented by two tabs rather than one. This 
33convention provides an easy, visual way to determine which code is 
34part of which conditional.*/
