Error while constructing an object mentioning another type












0














The compiler constantly shows the following errors referring to a different class constructor prototype. Point2D is another class which is used to construct the Line2D object.




C:Users*****srcLine2D.cpp|3|error: no matching function for call to 'Point2D::Point2D()'
includePoint2D.h|13|note: candidate: Point2D::Point2D(int, int)|




//this file(Line2D.h) has #include "Point2D.h"
Line2D(Point2D ,Point2D ); // constructor prototype

//this file(Line2D.cpp) has #include "Line2D.h"

          Oh, the issue is that your constructor is using a default constructor for Point2D that doesn't exist.



          Use initialization lists:



          Line2D::Line2D(Point2D pt1,Point2D pt2):pt1(pt1), pt2(pt2){}

            I think you missed the implementation for default constructor for Point2D class.
