/*
 * Function overloading/early binding/ early loading based on 
 * 1. types of parameters
 * 2. no of parameters
 * 3. sequence of parameters
 * 
 * 
 * 
 * 
 * 
 * 
 *Constructor
 *What - function whose name is same as class name, no return type
 *used for initialize object
 *invoked during object creation
 * 
 *you can have either implicit or explicit constructor but not both at same time
 *class A {} //imploicit
 *
 *class A
 *{
 *	A(int a)
 *  {
 *  
 *  }
 *}
 * 
 * Function overloading is not possible with return type
