public:
   void init(const int b) {b_sal = b; your_bonus = 0;}
   void  calc_bonus(const double perc){ your_bonus = b_sal * perc; }
   static void  reset_all(const int p){ all_bonus = p; }
   int  comp_tot() const{ return (b_sal + your_bonus + all_bonus); }
private:
   int         b_sal;
   int         your_bonus;
   static int  all_bonus;     //declaration

   w1.init(1000);
   w2.init(2000);
   w1.calc_bonus(0.2);
