After writing this program, debugging it, I am not getting desired output:
using namespace std;
class point 
	int x;
	int y;
	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;
	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;

What is the output that you get?

Did you DEBUG and see how the execution flows?

Let's see, this is not a question, it is a mere code dump.
I can see this is your first post here, but you should have read the posting guidelines that appear when you are creating your question.
Improve it putting a little of effort in it and please describe your problem clearly.
Sandeep has done that for you, but you should put your code snippets inside code blocks.

You did not include math.h for the sqrt function. What is your definition of "desired output"?

Solution 3

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 ...

No Richard, no... this is completely wrong, the program had to represent pink unicorns in the screen, a completely correct mathematical result is not desired... :rolleyes: <= this is a small joke... This morning, when I've seen this post I've not been able to find out anything special or strange in it... You've just confirmed it... It works... X|

:)) You could just have posted the joke here, I think I would have understood your point.

Wow... oddly enough, that is exactly the same answer I got.... :-)
