Object$-$Oriented VS$.$ Functional:

There are three types of line segments, horizontal, vertical or oblique. Verify whether a line segment is horizontal, vertical or oblique. From this diagram we can understand that:

$$ For Horizontal lines, the y coordinate values of two endpoints are same.

$$ For Vertical lines, the x coordinate values of two endpoints are same.

$$ For Oblique lines, the $($x$,$ y$)$ coordinates of two endpoints are different.

Write a program, for given two points, calculate the logic to verify it is Horizontal line, Vertical line or Oblique line. Implement this by using three paradigms: Object oriented Programming$($C$++),$ Functional Programming$($F#$)$ and Logic Programming $($SWI$-$Prolog$).$
