1、实验九 运算符重载（一）1、 实验目的理解运算符重载的概念和实质，掌握运算符重载函数的定义方法，掌握将运算符重载为类的成员函数和友元函数的方法，掌握和运用几种常用的用 C+语言运算符的重载进行解决问题的方法。2、 实验内容(1) 编写程序，运用运算符重载实现点类 Point 的两个对象(即两点)间横、纵坐标的相加运算。/ 1234.cpp : 定义控制台应用程序的入口点。/#include “stdafx.h“#include using namespace std;class pointpublic:point()x=0;y=0;point(int x1,int y1)x=x1;y=y1;p
2、oint operator + (point void display();private:int x;int y;point point :operator + (point p.x=x+p2.x;p.y=y+p2.y;return p;void point:display()coutusing namespace std;class Complexpublic:Complex()real=0;imag=0;Complex(double r,double i)real=r;imag=i;Complex operator*(Complex Complex operator/(Complex v
3、oid display();private:double real;double imag;Complex Complex:operator*(Complex c.real=real*c2.real-imag*c2.imag;c.imag=imag*c2.real+real*c2.imag;return c;Complex Complex:operator/(Complex c.real=(real*c2.real+imag*c2.imag)/(c2.real*c2.real+c2.imag*c2.imag);c.imag=(imag*c2.real-real*c2.imag)/(c2.rea
4、l*c2.real+c2.imag*c2.imag);return c;void Complex:display()coutusing namespace std;/(3) 设计一个长方形类Triangle，包含长和宽两个私有数据成员。要求重载运算符“+”，以实现多个矩形对象的面积之和。class rectangleprivate :int a,b;protected :int area;public:rectangle ()a=0,b=0,area=0;rectangle (int ra,int rb)a=ra;b=rb;area=ra*rb;rectangle operator+(rectangle void display();rectangle rectangle: operator+(rectangle r.area=area+r2.area ;return r;void rectangle :display()cout“a “a“ b “b“ area: “areaendl;int main()rectangle t1(2,3), t2(3,5),t3;t3=t1+t2;t3.display ();return 0;实验小结
