In C++

Connect-4 Game. A simple two player game, much like Tic-tac-toe.It is played on an 8 by 8 board. One player has X pieces and theother has O pieces. The players take turns, with X moving first.The goal is to make four in a row either horizontally, vertically,or diagonally. The program should support two human players or onehuman versus computer. It should reject illegal moves and it shoulddetect when the game ends (win or draw).

Please finish the game ”Connect4“ according to the existingcode.
