定义一个表示三维空间坐标点的类CTriplePoint,并对下列运算符重载。
1.+:加法操作，将三维点的对应坐标相加，返回一个CTriplePoint类的对象
2.<<:按（x,y,z）格式输出该点坐标（坐标为整形）
要求该类的设计使下列主函数能正确运行并输出结果:
voidmain（）
CTriplePoint myTriplepoint1（1.2.3）
CTriplePoint myTriplePoint2（4.5.6）
cout<<my1+my2<<endl；
输出结果:5，7，9

Answer 1

public class CTriplePoint{
int x;
int y;
int z;
public CTriplePoint(int x,int y,int z){
this.x = x;
tihs.y = y;
tihs.z = z;
}
public :
friend CTriplePoint operator+(CTriplePoint &c1,CTriplePoint &c2);
friend CTriplePoint operator<<(ostream &out,CTriplePoint &c);

CTriplePoint operator+(CTriplePoint &c1,CTriplePoint &c2){
return CTriplePoint(c1.x+c2.x,c1.y+c2.y,c1.z+c2.z);

}
ostream operator<<(ostream &out,CTriplePoint &c){
out<<"("<<c.x<<","<<c.y<<","<<c.z<<")";

return out;
}
}
