FeetInches Class Copy Constructor and multiply Function Add a copy constructor to the FeetInches class. This constructor should accept a FeetInches object as an argument. The constructor should assign to the feet attribute the value in the argument's feet attribute, and assign to the inches attribute the value in the argument's inches attribute. As a result, the new object will be a copy of the argument object. Next, add a multiply member function to the Feet Inches class. The multiply function should accept a FeetInches object as an argument. The argument object's feet and inches attributes will be multiplied by the calling object's feet and inches attributes, and a FeetInches object containing the result will be returned
