Fraction Program (Version 3)
Assignment
Convert the member functions in your fraction class (lab #5) into overloaded operators as
described below. Modify your calc program to utilize the overloaded operators.
Program Description
1. Convert the four arithmetic functions to overloaded operators (note that all parameters
and returns are pass-by-value and that all operators are members of the fraction class)
a. friend fraction operator+(fraction f1, fraction f2)
b. friend fraction operator-(fraction f1, fraction f2)
c. friend fraction operator*(fraction f1, fraction f2)
d. friend fraction operator/(fraction f1, fraction f2)
e. Friend functions are NOT members of a class. However, they are declared (i.e.,
prototyped) in the class and the keyword “friend” allows them to access the
private data contained in the class.
2. Replace the print function with operator<< as demonstrated in class (see pp. 616-
620). Make it inline or a regular function as you choose.
3. Convert the read function to operator>> as demonstrated in class. It may be either
inline or a regular function as you choose.
4. A conversion constructor has one parameter and converts one data type to another (the
parameter type to the class-type of the defining class). For example:
fraction(int n) : numerator(n), denominator(1) {}
is a conversion constructor that converts the integer n into the fraction n/1. By using
default parameters, it is often possible to make one constructor serve both as a “normal”
constructor and as a conversion constructor. You created a conversion constructor in Lab
#4:
fraction(int n, int d = 1) . . .
