Take the user choice and print 2D shapes based on the choice. A shape with only two dimensions (such as width and height) and no thickness. Squares, Circles, Triangles etc are two dimensional objects. These shapes mostly contain mathematical figures such are a line, square, triangle, rectangle and hexagon. The shapes are given below :
Circle : Radius = 4
*****
** **
** **
* *
* *
* *
** **
** **
*****
Square : Side = 4
****
* *
* *
****
Rectangle : Length = 3, Breadth = 8
********
* *
********
Triangle : Side = 4
*

Hexagon : Side = 4
