USING CODE ABOVE, FOLLOW DIRECTIONS BELOW AND MODIFY or Add to it:

Write statements to prompt for a value for numerator and then read it via cin to the num variable, and prompt for denominator and read it in to the den variable.

Call your setNumerator() on f1 and set numerator to value in num.

In addition, call setDenominator() on f1 to set denominator to value in den.

Use the print() function/method to print values for both f1 and f2.

For f2, it can be something like this:

cout <<

----------------------------------------------------------

sample output:
Enter numeartor of fraction f1: 1
Enter denominator of fraction f1: 2
Enter numeartor of fraction f3: 2
Enter denominator of fraction f3: 4

Fraction f1 is 1/2

Fraction f2 is 2/5

Fraction f3 is 2/4
Calling multiply method on f3 with f1 and f2 as arguments :
2/10
