Going on to the next example in group three, we find three simple
variables used in the conditional part of the compare. Since all three are
non-zero, all three are true, and therefore the AND of the three
variables are true, leading to the result being true, and z being assigned
the value of 11. Note that since the variables r, s, and t are float type
variables, they could not be used this way, but they could each be
compared to zero and the same type of expression could be used.
