矩形类继承实现

矩形类继承实现 矩形类继承实现_C++

// 
题目描述
1、定义一个Point类：
    包含：两个私有成员：m_x, m_y;
    包含：三个成员函数：Move(float xOff, float yOff)，GetX（），GetY（）
  
2、定义一个Rectangle继承自Point类
   包含：两个私有成员 m_width, m_height;
   包含：三个成员函数：GetHeight（）、GetWidth（）、printInfo（）
   
要求：通过构造函数实现初始化。
输入：矩形个数。如 5
输出：矩形信息。举例如下：


X: 5,Y: 5, GetWidth: 20, GetHeight: 10
X: 6,Y: 6, GetWidth: 21, GetHeight: 11
X: 7,Y: 7, GetWidth: 22, GetHeight: 12
X: 8,Y: 8, GetWidth: 23, GetHeight: 13
X: 9,Y: 9, GetWidth: 24, GetHeight: 14

注意：X，Y width，height的初始值分别为：2，3， 20，10
后面值的变化是根据循环变量i递增的。


需要先执行 Move 函数使得X，Y变成：2+3, 3+2


输入
5

输出
X: 5,Y: 5, GetWidth: 20, GetHeight: 10
X: 6,Y: 6, GetWidth: 21, GetHeight: 11
X: 7,Y: 7, GetWidth: 22, GetHeight: 12
X: 8,Y: 8, GetWidth: 23, GetHeight: 13
X: 9,Y: 9, GetWidth: 24, GetHeight: 14
样例输入 Copy
10
样例输出 Copy
X: 5,Y: 5, GetWidth: 20, GetHeight: 10
X: 6,Y: 6, GetWidth: 21, GetHeight: 11
X: 7,Y: 7, GetWidth: 22, GetHeight: 12
X: 8,Y: 8, GetWidth: 23, GetHeight: 13
X: 9,Y: 9, GetWidth: 24, GetHeight: 14
X: 10,Y: 10, GetWidth: 25, GetHeight: 15
X: 11,Y: 11, GetWidth: 26, GetHeight: 16
X: 12,Y: 12, GetWidth: 27, GetHeight: 17
X: 13,Y: 13, GetWidth: 28, GetHeight: 18
X: 14,Y: 14, GetWidth: 29, GetHeight: 19

class Point {
public:
	Point() {}
	Point(float X, float Y) {
		m_x = X;
		m_y = Y;

		return m_x;
	}
	float GetY() {
		return m_y;
	};

	float m_y;

class Rectangle :public Point {
public:
	Rectangle(float X, float Y, int wi, int he) :Point(X, Y) {
		m_width = wi;
		m_height = he;
	}
	int  GetHeight() {
		return m_height;
	};
	int  GetWidth() {

	void printInfo(int countm) {
		Move(3, 2);
		for (int i = 0; i < countm; i++) {
			cout << "X: " << GetX() + i << ",Y: " << GetY() + i << ", GetWidth: " << GetWidth() + i << ", GetHeight: " << GetHeight() + i << endl;
		}
	};
private:
	int m_width;
	int m_height;
};


int main() {
	int count = 0;
	cin >> count;
	Rectangle obj(2, 3, 20, 10);

	obj.printInfo(count);
	return 0;
