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;
#include

class calculator
{
public:
void Setnum1(int num1)
{
m_num1 = num1;
}
int Getnum1(void) const
{
return m_num1;
}
void Setnum2(int num2)
{
m_num2 = num2;
}
int Getnum2(void) const
{
return m_num2;
}

virtual int GetResult() = 0;

int m_num1;
int m_num2;

};

//加
class add :public calculator
{
public:
int GetResult()
{
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();
     }
}

};

class calculatorFactory
{
public:
static calculator* Create(char oper)
{
calculator poper = NULL;
switch (oper)
{
case '+':
poper = new add;
break;
case '-':
poper = new sub;
break;
case '':
poper = new mul;
break;
case '/':
poper = new divi;
break;

    }
    return poper;

}

};
int main()
{
cout << "请输入一个数字。"<<endl;
int num1;
cin >> num1;
cout << "输入运算符。" << endl;
char oper;
cin >> oper;
cout << "请输入一个数字。" << endl;
int num2;
cin >> num2;
calculator *poper = calculatorFactory::Create(oper);
poper->Setnum1(num1);
poper->Setnum2(num2);
cout << poper->Getnum1() << ' ' << oper << ' ' <Getnum2() << "=" << poper->GetResult() << endl;
system("pause");
return 0;
}

代码还是全放到代码快里面好，复制成文本显示后有些地方就不一样了。
总之，修改编译了一下，没什么问题了

#include<iostream>
using namespace std;

class calculator
{
public:
    void Setnum1(int num1)
    {
        m_num1 = num1;
    }
    int Getnum1(void) const
    {
        return m_num1;
    }
    void Setnum2(int num2)
    {
        m_num2 = num2;
    }
    int Getnum2(void) const
    {
        return m_num2;
    }

    virtual int GetResult() = 0;

    int m_num1;
    int m_num2;
};

//加
class add :public calculator
{
public:
    int GetResult()
    {
        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();
        }
    }
};

class calculatorFactory
{
public:
    static calculator* Create(char oper)
    {
        calculator *poper = NULL;
        switch (oper)
        {
        case '+':
            poper = new add;
            break;
        case '-':
            poper = new sub;
            break;
        case '*':
            poper = new mul;
            break;
        case '/':
            poper = new divi;
            break;

        }
        return poper;

    }
};
int main()
{
    cout << "请输入一个数字。" << endl;
    int num1;
    cin >> num1;
    cout << "输入运算符。" << endl;
    char oper;
    cin >> oper;
    cout << "请输入一个数字。" << endl;
    int num2;
    cin >> num2;
    calculator *poper = calculatorFactory::Create(oper);
    poper->Setnum1(num1);
    poper->Setnum2(num2);
    cout << poper->Getnum1() << ' ' << oper << ' ' <<poper->Getnum2() << "=" << poper->GetResult() << endl;
    system("pause");
    return 0;
}

代码修改如下：

#include <iostream>
using namespace std;


class calculator
{
public:
    void Setnum1(int num1)
    {
        m_num1 = num1;
    }
    int Getnum1(void) const
    {
        return m_num1;
    }
    void Setnum2(int num2)
    {
        m_num2 = num2;
    }
    int Getnum2(void) const
    {
        return m_num2;
    }

    virtual int GetResult() = 0;

    int m_num1;
    int m_num2;
};

//加
class add :public calculator
{
public:
    int GetResult()
    {
        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();
        }
    }
};

class calculatorFactory
{
public:
    static calculator* Create(char oper)
    {
        calculator* poper = NULL;
        switch (oper)
        {
        case '+':
            poper = new add;
            break;
        case '-':
            poper = new sub;
            break;
        case '*':
            poper = new mul;
            break;
        case '/':
            poper = new divi;
            break;

        }
        return poper;

    }
};
int main()
{
    cout << "请输入一个数字。"<<endl;
    int num1;
    cin >> num1;
    cout << "输入运算符。" << endl;
    char oper;
    cin >> oper;
    cout << "请输入一个数字。" << endl;
    int num2;
    cin >> num2;
    calculator *poper = calculatorFactory::Create(oper);
    poper->Setnum1(num1);
    poper->Setnum2(num2);
    cout << poper->Getnum1() << ' ' << oper << ' ' << poper->Getnum2() << "=" << poper->GetResult() << endl;
    system("pause");
    return 0;
}
