Now it is time to develop a program that uses an array of pointers to class
objects. The program is a modification of the program in Segment 388
that reads cylinder radii and lengths, puts them into an array of
cylinder
objects, and displays their total volume.
The modified program does the same work, but differs in that memory is
allocated for the pointers at compile time, leaving memory for the
cylinder
objects to be allocated at run time.
