Make a base class for a Polygon

The private members

• numOfSides : int
• sides[ ]: int // listed in clockwise order , MAX sides is 100

The attributes

• + Polyon(numSides:int) // default is 0
• + set(sideNum: int, value:int) : void// ensures no negative side values
• + get (sideNum:int):int // returns the value of sides[sideNum]
• + perimeter(): int virtual// returns the perimeter of the polygon
• + area(): double virtual //returns the area of the polygon

Make a class for Rectangle derived from Polygon

The attributes

• + Rectangle()// class Polygon(4);
• + area() // appropriately
• + perimeter()() // appropriately

Make a class for Square derived from Rectangle

The attributes

• + Square()// appropriately
• + area() // appropriately
• + perimeter() // appropriately

Make a class for RightTri derived from Polygon

The attributes

• + RightTri()// class Polygon(3); //. Assumes the order side, side, hypotenus
• + area() // appropriately
• + perimeter() // appropriately

Make a class for RectSolid derived from Rectangle

The members

• -height: int

The attributes

• + volume ()// returns the volume

In your main

• Make a an array of pointers to Polygon and add an instance Of a rectangle with sides of length 4 and 10
• A square with sides of length 5
• A right triangle with sides 3, 4 and 5
• A rectangular solid with sides of length 6 and 3 and height 5.
• Use the array to have each shape print out its area perimeter , as well As the rectangular solid print out its volume.
