I'm having trouble getting this working. Here are the errors I get while compiling. Can someone please help me with these errors?

Let's look at just a couple of the errors and see what could be the cause.

LineSegment.cpp: In constructor ‘LineSegment::LineSegment()’:
LineSegment.cpp:13: error: no matching function for call to ‘LineSegment::setEnd1(int)’
LineSegment.hpp:14: note: candidates are: void LineSegment::setEnd1(Point)
LineSegment.cpp:14: error: no matching function for call to ‘LineSegment::setEnd2(int)’
LineSegment.hpp:16: note: candidates are: void LineSegment::setEnd2(Point)
1
2
3
4
5
 
LineSegment::LineSegment()
{
	setEnd1(0);
	setEnd2(0);
}

SetEnd1() and SetEnd2() require a Point as input, 0 (zero) is an integer. A possible rewrite could be:
1
2
3
4
5
 
LineSegment::LineSegment()
{
   setEnd1(Point(0, 0));
   setEnd2(Point(0, 0));
}


The next error block:
LineSegment.cpp: In member function ‘void LineSegment::setEnd1(Point)’:
LineSegment.cpp:19: error: no matching function for call to ‘Point::setXCoord()’
Point.hpp:12: note: candidates are: void Point::setXCoord(double)
1

5
 
void LineSegment::setEnd1(Point p1)
{
	p1.setXCoord();
	p1.setYCoord();
}

setXCoord() and setYCoord() both require a double to be passed, you are passing, well, NOTHING. Even if you were properly setting your p1 Point it would not last because you are only changing a copy of p1 passed into setEnd1().

Thank you for your help FurryGuy. I see the mistakes I made with them, and was able to get it working.
