Computer language C++ (Connect 4 game)( this is all the info that was givin no input or solution) I used the most recent version of Microsoft visual studio for this program)Your solution must have these classes and at least these fields / methods. Your program must use the methods described in a meaningful fashion. You can create additional fields or methods but these the below should be core methods in your solution. Checkers classfields:colormethods:Constructo rint getColor()string toString() - returns an attractive string representation of itselfBoard classfields:2D array of checkers - represents the game board (6 row by 7 column)methods:Constructorstring toString() - returns an attractive string representation of itselfThis needs to be an attractive table representation of the game board with aligned rows / columns with characters representing blank cells, cells with a red checkers in it and cells with a gold checkers in it. int dropChecker(Checker, int) - drops a checker object down a particular slot. Returns an int indicating success or not. int isWinner() - returns code number representing no winner or player number of winnerPlayer classfields:namecolormethods:Constr uctorget / set methods for fieldsstring toString() - string representation of itself. Example String representation of the board (X means blank, R means red checker, G means gold checker)X X X X X X XX X X X X X XX X X X X G XX X X X X R XX X X X X R XX R G G G R GMainYour program should create two Players and a Board. It should represent the initial Board to the screen. You should then alternate between player 1 and player 2 and randomly drop checkers down slots in the board. You should represent the board after each checker drop. This should stop if there is a winner or if the board fills up. You should be turning in a Checker. h, Checker. cpp, Board. h, Board. cpp, Player. h, Player. cpp and a main. cpp
