我有以下课程：

class risc { // singleton
    protected:
        static unsigned long registers[8];

    public:
        unsigned long operator [](int i)
        {
            return registers[i];
        }
};

正如你所看到的,我已经实现了方括号运算符“get”.
现在我想实现它的设置,即：risc [1] = 2.

如何做呢？

解决方法:

尝试这个：

class risc { // singleton
protected:
    static unsigned long registers[8];

public:
    unsigned long operator [](int i) const    {return registers[i];}
    unsigned long & operator [](int i) {return registers[i];}
};
