Class StrPrint

A class StrPrint is defined for you, in files strprint.h and strprint.cpp.

This class has:

• A string member with get and set functions getString and setString, written as usual.
• A constructor that sets the string member to a given value.
• A default constructor that sets the string member to the empty string.
• A virtual member function out that prints the string to a given output stream, or cout if no stream is given.

What to Do

Do as many of the following as you can before class ends. Along the way, maintain a program that demonstrates whatever functionality you have written. To allow for faster writing, you may put all the code you write into a single file, if you wish. But avoid modifying strprint.h or strprint.cpp.

1. Write a class Back derived from StrPrint. This new class should override function out to print the string backwards.
2. Your program should make objects of type StrPrint and Back and call member function out on each, using a pointer of type (StrPrint *).
3. Write another class derived from StrPrint that prints a string in some other (interesting?) way. Add code that uses it to your program.

Some Reminders

• Get things to compile first, right?
• Don’t Repeat Yourself!
