我正在尝试学习如何将c ++ 11用户定义的文字用于物理属性单元.问题是,我如何避免混合这些单位.所以(8.0_kg + 8.0_km) - >给出错误.任何想法的家伙？我是c ++的新手,善良.

class Mass{
    public:        
        //Mass(){
        //    cout << "only Mass units allowed in here" << endl;
        //}
        //~Mass();
        long double getWeight(long double a);        
        double car, house, cat;

    private:
        long double a;


    };


long double Mass::getWeight(long double w) {

    cout << "returning argument: " << w << '\n'<< endl;
    return 0;
}


long double operator"" _km(long double d) { return d * 1000.0; }
long double operator"" _m (long double d) {return d;}
