The functions in this example feature a pattern of procedural calls with only
init
and
getkey
invoked as a
result of events. Please appreciate the fact that there are many ways to program an application, including
the definition of functions. Generally, it is a good practice to split code up into small functions, but it is not
necessary. There are many places where similar lines of codes are repeated, so there is opportunity to
define more functions. The annotated document follows in Table 10-2.
