C++这段程序在最后test01时里面的Coffee和Tea两个变量报错E0322，请问怎么解决？

Question

#include <iostream>
using namespace std;

class AbstractDrinking
{
public:
    virtual void Boil() = 0;
    virtual void Brew() = 0;
    virtual void PourInCup() = 0;
    virtual void PutSomeThing() = 0;

    void MakeDrink()
    {
        Boil();
        Brew();
        PourInCup();
        PutSomeThing();
    }
};

class Coffee :public AbstractDrinking
{
public:
    virtual void Boil()
    {
        cout << "煮农夫山泉" << endl;
    }
    virtual void Brew()
    {
        cout << "冲泡咖啡" << endl;
    }
    virtual void PourInCup()
    {
        cout << "把咖啡倒入杯中" << endl;

    }
    virtual void PutSomething()
    {
        cout << "加入牛奶" << endl;
    }
};

class Tea :public AbstractDrinking
{
public:
    virtual void Boil()
    {
        cout << "煮自来水" << endl;
    }
    virtual void Brew()
    {
        cout << "冲泡茶叶" << endl;
    }
    virtual void PourInCup()
    {
        cout << "把茶叶倒入杯中" << endl;

    }
    virtual void PutSomething()
    {
        cout << "加入枸杞" << endl;
    }
};

void DoWork(AbstractDrinking* abs)
{
    abs->MakeDrink();
    delete abs;
}

void test01()
{
    DoWork(new Coffee);
    cout << "--------------" << endl;
    DoWork(new Tea);
}
int main()
{
    test01();
    system("pause");
    return 0;

}

```c++

原来在基类里啊
你子类的PutSomething函数和基类的PutSomeThing函数名称不同，是不行的
子类必须全部实现基类的抽象函数，否则子类还是个抽象类，不能实例化
改了就可以成功运行了
