CIS25 Fractions

A. Update the Fraction class given in the Lecture notes or as discussed in class meetings as follows,

1. Add your FIRST NAME and the initial of your last name to the name Fraction and use this as your updated class. For examples, if your first name is John Smith then update the class name to be FractionJohnS.

2. Add and update all class constructors for your Fraction class to handle the initialization appropriately.

There must be as least 2 constructors of
(i) Default; and
(ii) Copy.

Each constructor should print the confirmation (e.g., "Calling Fraction()", or Calling Fraction(const Fraction&)).

3. Provide a destructor with a confirmation when removing the object (i.e., "Calling ~Fraction()").

4. Provide get/set member functions for each private member data.

5. A member function print() that will print the current Fraction object.

B. Provide the following member functions,

• A function add() to add a Fraction object; and
• A function subtract() to subtract a Fraction object; and
• A function multiply() to multiply a Fraction object; and
• A function divide() to divide a Fraction object; and

C. Provide the following member operator functions,

• A function operator=() to assign a Fraction object.
• A function operator+() to add a Fraction object; and
• A function operator-() to subtract a Fraction object; and
• A function operator*() to multiply a Fraction object; and
• A function operator/() to divide a Fraction object; and

D. Provide the following stand-alone functions,

• A function init() to set up or update the 2 required Fraction objects.
• A function add() to add 2 Fraction objects; and
• A function subtract() to subtract 2 Fraction objects; and
• A function multiply() to multiply 2 Fraction objects; and
• A function divide() to divide 2 Fraction objects; and
• A function print() to print the required Fraction objects; and
• An appropriate menu() function to produce the required output as displayed below.

C. Run a driver named as cis25Spring2018YourNameHw4Ex1.cpp and record the output of the program.

(a) The output screen should have the following lines displayed before any other display or input can be seen,
