CS 132 Assignment 2

Due Wednesday, February 13:
1. Modify fractionType to overload operators as appropriate.

Due Friday, February 15
2. Fractions are normally assumed to have values between 0 and 1. A rational number,
   on the other hand, is any number that can be represented as a/b where a and b are 
   integers. Build a class rationalType that inherits from fractionType. 

   To think about:
    can you use the same private members?
    what additional member functions might you include?
    what member functions should be overloaded.
