I am trying to use a class to convert between miles, meters, inches, yards and feet. My instructor told me that I have way too many functions My return statements are not storing any values andMy print function is empty - which I think will make more sense to me once 1 & 2 are solved. How can I do this using less functions? Why aren't the return values storing anything? #include <string>#include <iostream>using namespace std;class DistanceConverter { //Class name    public:        DistanceConverter() { //Default constructor            miles_ = 0;        }        DistanceConverter(double Miles) { //Overload constructor            miles_ = Miles;        }        //Miles mutators and accessors        void SetMilesToMeters(double Miles) {            miles_ = Miles * 1609.34;        }        double GetMilesFromMeters() {            return miles_;        }        void SetMilesToInches(double Miles) {            miles_ = Miles * 63360;        }        double GetMilesFromInches() {            return miles_;        }        void SetMilesToFeet(double Miles) {            miles_ = Miles * 5280;        }        double GetMilesFromFeet() {            return miles_;        }        void SetMilesToYards(double Miles) {            miles_ = Miles * 1760;
