15 Puzzle Game in C Program

Program #36

Description:
15 Puzzle Game with full source source.  By Default program will load 1-15 number in randomly in 4x4 matrix.  User can use Arrow Keys (Up, Left, Right and Down) to arrange the Number in a proper order starts from 1,1 to 4,3.  Once all the values are arranged then Program will ends. 

Help Option !!  Free Moves option introduced to help user when user stuck!! By pressing ENTER key system will arrange next SEQUENCE number and use can continue the game!!.  Free Move is present in Defined constant and By default as 3 free moves.

Invalid Arrow Option!!  Program will dynamically display the Current Keypress in a User friendly manner and if user press invalid Arrow Key it will display it accordingly !!

Move Count!!  Program will count the Total number of Valid Key press and it will show in a User friendly manner and in case Invalid Key pressed, system will not counter it!!  In case user uses Free Move then only the Move Counter will get incremented to 1.. That's not a Problem!!
