/* class is nothing but a blueprint. it is reference type it can have filed , constructor
 * method property indexer and all.
 * Class is reference type so it will store object in heap; means reference store in heap memory and data
 * store in stack.
 *
 * class default access modifier is internal.
 * other all comes to inside private.
 * Enum and interface is public .
 *
 * Access modifier, static, return type, Main - method name.
 *
 *
 * object is basically block of memory that has been allocated to blueprint
 * A program can create as many object in same class, object are also called instance
 * They can store in array or list.
 * Object are reference type it can store in heap memory
 *
 * var obj = new Object();
 *
 * Interface :
 *  Interface is type definition similar to class except that is purely
 * a contract between object and user.
 * interface is nothing but collection of method, property deceleration.
 * interface can declare event and indexer as well
 * deceleration of the interface done in
