C ++程序未返回所需的输出 [英] C++ program not returning desired output

问题描述

编写此程序后，对其进行调试，我没有得到想要的输出:

After writing this program, debugging it, I am not getting desired output:

#include<iostream>
using namespace std;

class point 
{
private:
	int x;
	int y;
public:
	void setPoint(int xcoord,int ycoord)
	{
		x = xcoord; y = ycoord;
	}
	int getX()
	{return (x);}
	int getY()
	{return (y);}
	void showPoint()
	{	cout << "(" << x << ","<< y <<")";
	}
};
int main()
{
	point pt1,pt2;
	double dx, dy, dist;
	pt1.setPoint(-3,2);
	pt2.setPoint(2,5);
	dx = pt2.getX() - pt1.getX();
	dy = pt2.getY() - pt1.getY();
	dist = sqrt (dx*dx + dy*dy);
	cout << "The distance between two points"; pt1.showPoint();
	cout << "and";pt2.showPoint();
	cout << "is"<< dist << endl;
	return 0;

推荐答案

我刚刚对此进行了测试，答案是正确的:
dx等于5
dy等于3
dx * dx + dy * dy等于25 + 9 = 34
34的平方根是5.83095 ...

I just tested this and the answer is correct:
dx is equal to 5
dy is equal to 3
dx*dx + dy*dy is equal to 25 + 9 = 34
The square root of 34 is 5.83095 ...
