()这样的代码 friend std::ostream& operator<<(std::ostream& os, const Student& stu); public: std::string m_id;//学号 std::string m_name;//姓名 int m_age;//年龄 std::string m_date;//生日 }; std::ostream & operator<<(std::ostream & os, const Student & stu) { //向os输出...
现在让我示范一个overloaded operator的作法,只要在以下类的代码中加入第18~21行的+号的重载代码,即可完成CPoint的加法运算: 1classCPoint{23public:45CPoint()6{7_x=0;89}1011CPoint(floaty){1213_x=y;14}15floatx(){return_x;}16voidx(floatxval){_x=xval;}1718CPointoperator+(constCPoint& pt)co...
endl; } //在全局范围内重载+ complex operator+(const complex &A, const complex &B){ complex C; C.m_real = A.m_real + B.m_real; C.m_imag = A.m_imag + B.m_imag; return C; } int main(){ complex c1(4.3, 5.8); complex c2(2.4, 3.7); complex c3; c3 = c1 + c2; c3...
In this case, the operator is invoked by the first operand. Meaning, the line Complex c3 = c1 + c2; translates to c1.operator+(c2); Here, the number of arguments to the operator function is reduced by one because the first argument is used to invoke the function. ...
Operator Overloading讓我們可以自己定義Operator的功能,讓程式可以更精簡,C#也有,不過不是很強調,但C++非常強調Operator Overloading,這是C++的一大特色。 Introduction 以下程式我們試著實做一個『複數』型別,複數由實部,有虛部,複數的加法為(a + bi) + (c +di) = (a +c) + (b+d)i,乘法則是(a + ...
m_cents); } int main() { Cents c1(6), c2(8); Cents c3 = c1 + c2; Cents c4 = c1 + 2; cout << c3.getCents() << endl; cout << c4.getCents() << endl; return 0; } 和友元函数相比,成员函数的运算符重载只有一个参数。c1看起来变成了前缀。而这里隐藏了*this,即c1.operator...

operator deleteoperator delete [] II.不能重载的操作符 III.基本规则 1.一元操作符可以是不带参数的成员函数[1]或带一个参数的非成员函数[1]。 2.二元操作符可以是带一个参数的成员函数[1]或带两个参数的非成员函数[1]。 3.operator=、operator[]、operator()、operator->只能定义为成员函数[1]。
C# adopted the capability of operator overloading from C++. Just as you can overload methods, you can overload operators such as +, -, *, and so on. In addition to overloading arithmetic operators, you can also create custom conversion operators to convert from one type to another. You...
