You are required to create a simple desktop application to draw various shapes on the screen. The shapes should

include:

$1-$ Square

$2-$ Circle

$3-$ Rectangle

$4-$ Triangle

$5-$ Line

The application should have two modes: Drawing and Info.

In the drawing mode, the shapes should appear as choices on the left panel as shown

Once you select a shape, it should appear in the drawing area with a random position and random size. Once a shape

is inserted, its name should appear in the $$Shapes Names Area$.$ The shape name should be unique. When you select

a shape in the drawing area $($B$),$ its corresponding shape should be highlighted $($Figure $2).$ The same thing should

apply when selecting a shape in the drawing area. in the image below $($Figure $1).$

In the $$Info Mode$,$ the application should simply show info about the shapes on the screen in textual format $($See

figure $3)$

Programming Language?

You have to develop this project in Visual Studio using either C# or VB$.$NET. Visual Studio will help create the User

Interface easily while having all the Object$-$Oriented language constructs that you are familiar with in Java.

Task $1$: Class Diagram

The problem is not that difficult. You might end up with few class. However, remember that you are a $$Designer$$ not

only a programmer! You have to approach this problem having in mind that the requirements might get bigger

$($remember$,$ you have $2$ extra homeworks$).$ Develop a class diagram that reflects this structure and make sure to

follow the main principles we discussed in the class including:

$$ Abstraction and Encapsulation

$$ Single Responsibility Principle

$$ Open$-$Closed Principle

You have to include all fields and methods in every class with proper access modifiers $($private$,$ public, etc.$).$ If the

relation between two classes is an association, specify the multiplicity, label and direction of the relationship. Make

sure that your class diagram represents all needed components in this system and also the main application.

Task $2$: Develop the application

Develop your program to fulfill the requirements mentioned above.

NOTE: Your program should reflect your class diagram
