Now let us write a program to find out the Chinese Zodiac sign for a given year. The
Chinese Zodiac is based on a twelve-year cycle, with each year represented by an animal—
monkey, rooster, dog, pig, rat, ox, tiger, rabbit, dragon, snake, horse, or sheep—in this cycle,
as shown in Figure 3.7.

The Chinese Zodiac is based on a twelve-year cycle.
Note that
year % 12
determines the Zodiac sign. 1900 is the year of the rat because
1900
% 12
is
4
. Listing 3.10 gives a program that prompts the user to enter a year and displays the
animal for the year.
