Question

成员函数void readPayInfo（）在类BonusEmployee中重新定义。它现在返回数据成员基本工资的值加上数据成员奖金的值

class Employee
{
public:
      //constructors here
      void readPayInfo()
      {cin >> basePay;}
private:
      double basePay;
};


class BonusEmployee : public Employee
{
public:
      //constructors here
      void readPayInfo()
      {cin >> basePay >> bonus;} // NULL!
private:
      bonus;
};

如何从父类访问basePay？

Answer 1

由于您选择将Employee::basePay设为私有，因此无法从子类直接访问它。我认为你有两个选择：

将吸气剂添加到Employee或
将Employee::basePay的可见度更改为protected。

C ++派生类函数重定义
