    Default Connect Four FAIL....

    Lab 7 - #2

    Implement a Connect 4 game. The program should allow two players to play each other. For each turn, have the user enter the column they want to play in, validate the user has made a good move, and then place the piece on the board. Then the program should check for a winner and a tie, and assuming there is neither, redisplay the board and get the next players move. Display the moves using print/printf/println commands, and use an X for player 1 and an O for player 2. When the game ends, the program should display congratulations to the winner or announce there was a tie, and then allow the players to choose to play again or exit.

    You must use a 2D array for this lab.


    I believe i am on the right track but i am getting lost, any help would be so appreciated.


    import java.util.Scanner;
    public class Lab7
    {
    	public static void main(String args[])
    	{
    		// create board
    		int cFBoard[][] = new int[7][8];
    		Scanner input = new Scanner(System.in);
    		//loop
     
     
    			//init board
     
     
    			// currentPlayer = 1, numMoves = 0;
    			int cPlayer = 1;
    			int pAgain;
    			int nMoves=0;
     
     
    			//LOOP
     
    			// display board
    			System.out.println("\t1\t2\t3\t4\t5\t6\t7");
     
    			for (int r = 1; r <= 6; r++)
    			{
    				System.out.print(r);
     
    				for(int c = 1; c <= 7; c++)
    				{
    					System.out.print("\t" + cFBoard[r][c]);
    				}
    					System.out.println();
    			}
     
    				int c;
     
    			// get move
    			do
    			{
     
    					System.out.print("Input desired column: ");
    					  	C = input.nextInt();
     
    			}
    			while (c < 1||c > 7|| cFBoard[6][c] !=0);
     
     
     
     
    			// place piece
     
     
    			for(int r = 1; r<=6; r++);
    			 {
     
    				if (cFBoard[r][c]==0)
    				{
     					cFBoard[r][c] = cPlayer;
     					playerConvert();
     
    				}
     
    			 }
    			//Check winner
    	}
    }
     
     
    class playerConvert
    {
    public String convert(int cPlayer)
    		{
    			if (cPlayer == 1)
    			{
    				return "X";
    			}
    			else if (cPlayer == 2)
    			{
    				return "O";
    			}
    			else
    			{
    				return "-";
    			}
    		}
    }

    		// display board
    		// get move (includes validation)
    		// place piece
    		// check winner
    		// check tie
    		// change currentPlayer
    	END LOOP
    	// Display congratulations/tie
    	// do you want to play again
    // END LOOP
     
    DATA NEEDED
    Int board[][]
    Int currentPlayer
    bool playAgain
    int numMoves
     
    GAME BOARD
    int board [] [] = new int[7][8]	
    Using rows 1-6 and columns 1-7 and ignoring element 0

    DISPLAYING BOARD
    See the last in class problem
     
     
    CONVERT ROUTINE
    public String convert(int i)
    {
    	if (I == 1)
    {
    		Return “X”;
    }
    	else if (I == 2)
    {
    		Return “O”;
    }
    	else
    {
    		Return “-”;
    }
    }
     
    VALIDATE MOVE
    do
    {
    // get move
    }
    while (col < 1 || col <> 7 || board [6][col] != 0);
     
    PLACEMENT
    for(int i = 1; i<=6; i++);
     {
    	if (board[i][col]==0)
    	{
    		board[i][col] = current player;
    		break;
    	}
     }
     
    HORIZONTAL CHECK FOR WIN
    for (int r = 1; r < = 6; r++)
    {
        for int c = 1; c <=4; c++)
    	    {
     	        if (board [r][c] == board [r][c+1] && 
    board[r][c+1] == board[r][c+2] &&                                        
    board[r][c+2] == board[r][c+3] && 
                  board[r][c] != 0)
            {
                  win = true;
             }
         }
    }

    Ask a specific question, get a specific answer. Ask a vague question (or none at all), and get a link to the following:
    How to Help Yourself Get Help
    I recommend reading the above, and use the suggestions within to provide context and questions to your post, which always increases your chances of receiving the help you want.
