//定义一个Point类，要求至少具有x坐标和y坐标两个私有属性。 //至少定义一个公有的方法，实现让该点自身移动位置的功能。 //定义一个Line类，一个Line由两个Point属性，分别是startPoint和endPoint， //至少有一个方法，能够根据点坐标计算Line的长度。 //在main()函数中定义两个Point对象，并根据这两个Point定义一个Line的对象， //通过构造函数完成其属性的初始化，计算并输出坐标和长度。将两个点的x、y分别移动之后，再重新计算Line的坐标和长度。 #include <iostream> #include "Point.h" #include "Line.h" using namespace std; int main() { double x1, x2, y1, y2; cout << "请输入第一个点的坐标" << endl; cin >> x1 >> y1; cout << "请输入第2个点的坐标" << endl; cin >> x2 >> y2; Point point1(x1,y1); Point point2; point2.setX(x2); point2.setY(y2); Line line(point1, point2); cout << "line的起点为：" << "（" << line.getStartPoint().getX() << "," << line.getStartPoint().getY() << ")"<<endl; cout << "line的终点为：" << "（" << line.getEendPoint().getX() << "," << line.getEendPoint().getY() << ")"<<endl; cout << "line的长度为：" << line.calculatLength()<<endl; double dx1, dx2, dy1, dy2; cout << "请分别输入起点的移动量" << endl; cin >> dx1 >> dy1; cout << "请分别输入终点的移动量" << endl; cin >> dx2 >> dy2; cout << "移动起止点" << endl; point1.move(dx1, dy1); point2.move(dx2, dy2); line.updatePoint(point1, point2); cout << "line的起点为：" << "（" << line.getStartPoint().getX() << "," << line.getStartPoint().getY() << ")" << endl; cout << "line的终点为：" << "（" << line.getEendPoint().getX() << "," << line.getEendPoint().getY() << ")" << endl; cout << "line的长度为：" << line.calculatLength() << endl; return 0; }
