c++编译的 计算器
问题是 运行之后为什么 显示的是地址 做运算 我应该怎么改正

#include
using namespace std;

class calculator
{
public:
void Setnum1(int num1)
{
m_num1 = num1;
}
int Getnum1(void) const
{
return m_num1;
}
void Setnum2(int num2)
{

}
int Getnum2(void) const

}

virtual int GetResult() = 0;

int m_num1;
int m_num2;

};

//加
class add :public calculator
{
public:

{
return Getnum1() + Getnum2();
}
};

//减
class sub :public calculator
{
public:
int GetResult()
{
return Getnum1() - Getnum2();
}
};

//乘
class mul :public calculator
{
public:
int GetResult()
{
return Getnum1() * Getnum2();
}
};

//除
class divi :public calculator
{
public:
int GetResult()
{
if (Getnum2() == 0)
{
cout << "除数不可以为零。" << endl;
}

     else  
     {
         return Getnum1() / Getnum2();
     }
}

};

case '-':

case '':

case '/':

    }
    return poper;
