面向对象程序设计上机练习十一（运算符重载）

#include<iostream>#include<cstring>using namespace std;class Complex{public :  Complex(){x1=0;x2=0;x3=0;y1=0;y2=0;y3=0;}  Complex(int a,int b,int c,int d,int e,int f){x1=a;x2=b;x3=c;y1=d;y2=e;y3=f;}  Complex operator +(Complex &t);  friend ostream& operator <<(ostream&, Complex&);//一定要定义为友元函数，如果是重载双目操作符（即为类的成员函数），就只要设置一个参数作为右侧运算量，而左侧运算量就是对象本身。。。。。。而 >>  或<< 左侧运算量是 cin或cout 而不是对象本身，所以不满足后面一点void setting();private:    int x1,x2,x3;    int y1,y2,y3;};Complex Complex:: operator+( Complex &t)    {        return Complex(x1+t.x1,x2+t.x2,x3+t.x3,y1+t.y1,y2+t.y2,y3+t.y3);    }ostream& operator <<(ostream &output, Complex &c)   {       output<<c.x1<<" "<<c.x2<<" "<<c.x3<<endl;       output<<c.y1<<" "<<c.y2<<" "<<c.y3<<endl;   }void Complex::setting(){    cin>>x1>>x2>>x3>>y1>>y2>>y3;}int main(){    int e;    Complex t1,t2,t3;    t1.setting();    t2.setting();    t3=t1+t2;    cout<<t3;    return 0;}
