  • 第1题:

    下列运算符函数中,肯定不属于类Value的成员函数的是( )。

    A.Value operator+(Value);

    B.Value operator-(Value,Value);

    C.Value operator*(int);

    D.Value operator/(Value);


    正确答案:B
    解析:此题考查的是运算符“-”的重载。“-”运算符有一元和二元两种,且均可以重载为成员函数和非成员函数。运算符重载为成员函数时,形参个数一般为运算符元素减1;重载为非成员函数时,形参个数一般和运算符元素相等。所以“-”运算符重载为成员函数时,参数可以是。个或1个;而重载为非成员函数时,参数个数可以是1个或2个。所以选项B),肯定是重载为非成员函数。
