黑马程序员——点和圆的关系

在这里分享的，我并没有把class类拆分

#include 
#include 
using namespace std;
#include "circle.h"
#include "point.h"
class point {
public:
	void setx(int x) {
		m_x = x;
	}
	int getx() {
		return m_x;
	}
	void sety(int y) {
		m_y = y;
	}
	int gety() {
		return m_y;
	}
private:
	int m_x;
	int m_y;
};

class circle {
public:
	void setr(int x) {
		r = x;
	}
	int getr() {
		return r;
	}
	void setc(point c) {
		center = c;
	}
	point getc() {
		return center;
	}
private:
	int r;
	point center;
};

void iscircle(circle& c, point& p) {
	if ((c.getc().getx() - p.getx()) * (c.getc().getx() - p.getx()) + (c.getc().gety() - p.gety()) * (c.getc().gety() - p.gety()) > c.getr()* c.getr()) {
		cout << "点在圆外" << endl;
	}
	else if ((c.getc().getx() - p.getx()) * (c.getc().getx() - p.getx()) + (c.getc().gety() - p.gety()) * (c.getc().gety() - p.gety()) == c.getr()* c.getr()) {
		cout << "点在圆上" << endl;

	}
	else {
		cout << "点在圆内" << endl;
	}
}
int main() {

	circle c1;
	c1.setr(2);
	point cen;
	cen.setx(0);
	cen.sety(0);
	c1.setc(cen);
	point a;
	a.setx(2);
	a.sety(0);
	iscircle(c1, a);
	system("pause");
	return 0;
}

这两天浪费了，明天立个flag，把对象特性和运算符重载学完！！！
