In C++ please and if you could do and explain each step thank you 1.Add a main method to the FeetInches class. The main method should create three FeetInches objects. 2.Create one object named sum_length using the no-parameters constructor. 3.For the other two, prompt the user to enter a number of feet and a number of inches, and construct a FeetInches object using the two parameter constructor. 4.Do this twice, to create the two objects named length1 and length2. 5.Then test the equals method by using it to compare the objects. 6.ALso, test the add method by adding the two lengths length1 and length2 and assiigning the result to the sum_length object. 7.Print the result of the length comparison and print the sum_length. Test the setFeet and setInches methods on sum_length and print it after each set operation to verify it changed properly. #include #include #include using namespace std; /** The FeetInches class holds distances measured in feet and inches. */ class FeetInches { private: int feet; // The number of feet int inches; // The number of inches void simplify() { if (inches > 11) { feet = feet + (inches / 12); inches = inches % 12; } } /** This constructor assigns 0 to the feet and inches fields. */ public: FeetInches() { feet = 0; inches = 0; } /** This constructor accepts two arguments which are assigned to the feet and inches fields.
