C$++$ Not sure how to set up to derive and override the line class from the shape class and how to get the line class to draw itself on the console window.

Add a Line class to the Graphics project. The Line class should derive from Shape.

Add $1$ Point$2$D field called endPt. Add getter$/$setter methods for the field.

Add a constructor that takes a start Point$2$D$,$ end Point$2$D$,$ and console color. Make sure to call the base constructor. Don$$t duplicate what the base constructors do$.$

Implement the pseudocode for the PlotLine $($see the pseudo$-$code for PlotLine below$).$ NOTE: you$$ll need to implement the Plot method $$ it should move the cursor to the x$,$y

position and prints a space.

Override the draw method of the Shape class $($that means you need to mark the base as virtual$).$ Do not call the base. Instead, set the background color, call PlotLine, then reset

the color.

PlotLine$($x$0,$ y$0,$ x$1,$ y$1)$

dx $=$ abs$($x$1-$ x$0)$

sx $=$ x$0<$ x$1?1$ : $-1$

dy $=-$abs$($y$1-$ y$0)$

sy $=$ y$0<$ y$1?1$ : $-1$

error $=$ dx $+$ dy

while true

Plot$($x$0,$ y$0)$

if x$0==$ x$1$ && y$0==$ y$1$ break

e$2=2*$ error

if e$2>=$ dy

if x$0==$ x$1$ break

error $=$ error $+$ dy

x$0=$ x$0+$ sx

end if

if e$2<=$ dx

if y$0==$ y$1$ break

error $=$ error $+$ dx

y$0=$ y$0+$ sy

end if

end while

In main $($which is in Graphics.cpp$),$ add code to case $2$ of the menu switch. Generate $2$ random Point$2$D points with an x$,$y anywhere in the console. Use those points to create a

Line instance with any color you want. Call draw on the Line instance.
