c++

1. Create a class called Shape
   • this class must not be instantiable.
   • it has 2 attributes. int numOfSides, float lengthOfSides[]
   • it has 4 methods
     • calculateArea(),
     • calculatePerimeter()
     • showData()
     • findLarger(Shape* s2) - this finds the larger of 2 shapes, based on area and uses showData() to print out the data of the larger Shape
2. Define 2 derived classes of Shape called Circle and Rectangle
   • Circle: numOfSides = 1 (the radius is kept in lengthOfSide[0])
     • Area = *r*r
     • Perimeter = 2 * * r
     • showData() will print out Circle: Radius 5, Area = 78.5375... (it is enough to show only a few decimal digits)
   • Rectangle: numOfSides = 4, opposite sides are equal a, b
     • Area = a*b
     • Perimeter = 2* (a + b)
     • showData() will print out Rectangle: 5,2, 5, 2 Area = 10
     • isSquare() returns true if all the sides are equal
3. Define a main() in ShapeDriver.cpp and test the following
   • Instantiate one Circle with a radius of 10
     • Run showData() on that circle
     • Run findLarger by comparing with another Circle whose radius is 4.5
   • Instantiate 2 Rectangles
     • rect1 with sides 5,4, 5,4 and rect2 with sides 5,5,5,5
     • Run showData() on rect1
     • findLarger comparing it to rect2
     • Run isSquare() on both rect1 and rect2
   • Add all these Shapes to any kind of STL container you wish to and run showData() on all the objects added to that container
