Lab 6

Lab 6 - Due May 10th

In this lab, we will implement create a Fraction class, complete with operator overloading and overloaded input and output operators. Here is the header file:

#ifndef _FRACTION_H_
#define _FRACTION_H_

class Fraction 
{
   friend ostream &operator<<( ostream&, const Fraction&);
   friend istream &operator>>( istream&, Fraction&);

   public:
 
   //ctors
   Fraction (int num = 0, int dem = 1);
   Fraction (const Fraction& other);  

   //Assignment 

   const Fraction& operator=(const Fraction& rhs);
   const Fraction& operator+=(const Fraction& rhs);

   //Arithmetic

   Fraction operator+(const Fraction& rhs) const;
   Fraction operator-(const Fraction& rhs) const;
   Fraction operator*(const Fraction& rhs) const;

   //Other functions
   void print (ostream & out = cout) const;
   bool equals(const Fraction& rhs) const;
    

   private:
  
   int numerator;
   int denominator;

}

#endif

Your job is to implement all of these methods and turn this into a working class. Don't get scared! It's not as hard as it looks, and the book provides some really good examples.

Hints:

Don't worry about simplifying fractions. If you multiply 2/5 * 5/5, having 10/25 (as opposed to 2/5) as your answer is acceptable.

What to hand in:

Both the .h and the .cc file, as well as a test program you create that shows off all this functionality.
