Goal: Write a Class to represent Fractions

Write a Fraction class whose objects will represent fractions. For example, a fraction of 3/7 will be represented by a Fraction object whose numerator will be set to 3 and denominator will be set to 7.

Implementation

Note: For this checkpoint

do not reduce fractions (i.e. 15/18 should NOT be reduced to 5/6),
do not use "const" (since we haven't discussed in class yet)

Attributes:

Your class should have exactly two private data members, one to represent the numerator of the Fraction being represented, and one to represent the denominator of the Fraction being represented. (What should be the data type of these member variables?)

Member functions:

A default constructor that sets the fraction to 0 (what should be the numerator and denominator for such a fraction?).
A parametrized constructor takes two integer arguments, a numerator and a denominator, and assigns the attributes accordingly.
Arithmetic operations that add, subtract, multiply, and divide Fractions. They should be named addedTo, subtract, multipliedBy, and dividedBy. These return a Fraction object. In these functions you will need to declare a local "Fraction" variable, assign to it the result of the mathematical operation, and then return it.
A boolean operation named isEqualTo that compares two Fraction objects for equality. Since you aren't reducing your Fractions, you'll need to do this by cross-multiplying. A little review: if numerator1 * denominator2 equals denominator1 * numerator2, then the Fractions are equal.
An output operation named print that displays the value of a Fraction object on the screen in the form numerator/denominator.

Hints

When adding or subtracting Fractions, remember that you must first find the common denominator. The easy way to do this (and that you must follow for this checkpoint since we are not simplifying fractions) is to multiply the denominators together and use that product as the common denominator.

The difference of 9/8 and 2/3 is 11/24
The two Fractions (f1 and f2) are not equal.
The two Fractions (f3 and f4) are equal.

As you can see from the sample output given above, you are not required to reduce Fractions or change improper Fractions into mixed numbers for printing. Just print it as an improper Fraction. You are also not required to deal with negative numbers, either in the numerator or the denominator.
