Answer 1

#include <iostream>
using namespace std;
class Distance{
    int meters, centimeters;
    public:
        Distance(int m, int cm): meters(m), centimeters(cm){
            while(centimeters >= 100){
                centimeters -= 100;
                meters += 1;
            }
        }
        void show(){
            cout<<meters<<" meters"<<" "<<centimeters<<" centimeters"<<endl;
        }
        Distance operator-(){
            return Distance(this->meters * -1, this->centimeters * -1);
        }
        Distance operator+(const Distance &other){
            return Distance(this->meters + other.meters, this->centimeters + other.centimeters);
        }
};
int main(){
    Distance distA(4, 4), distB(5, 534);
    cout<<"A = ";distA.show();
    cout<<"B = ";distB.show();
    cout<<"-A + B = "; (-distA + distB).show();
    return 0;
