Program to print 2D shapes

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

    ****    
   ******   
  ********  
 **********
