Question

嘿伙计们我用C ++编写了一个连接四个程序，但是我很难用我的算法找出问题，找出对角线的获胜动作。这是我写的代码：我的水平和垂直函数可以工作

//checks for a horizontal win
    //returns 1 if there's a win
    for(int i=0;i<numrows;i++)
        for(int j=0;j<rowsize-3;j++)
            if(board[i][j]!=" " && board[i][j]==board[i][j+1] && board[i][j]==board[i][j+2] && board[i][j]==board[i][j+3])
                return 1;

    //checks for a vertical win
    //returns one if theres a win
    for(int i=0;i<numrows-3;i++)
        for(int j=0;j<rowsize;j++)
            if(board[i][j] !=" " && board[i][j]==board[i+1][j] && board[i][j]==board[i+2][j] && board[i][j]==board[i+3][j])
                return 1;  



    int numrows=6;
    int rowsize=7;

//checks the right side of a diagonal for a  win
    for(int i=0;i<numrows;i++)
        for(int j=0;j<rowsize;j++)
            if(board[i][j] !=" " && board[i][j]==board[i+1][j+1] && board[i][j]==board[i+2][j+2] && board[i][j]==board[i+3][j+3])
                return 1;


    //checks left diagonal win for a win
    for(int i=0;i<numrows;i++)
        for(int j=0;j<rowsize;j++)
            if(board[i][j] !=" " && board[i][j]==board[i+1][j-1] && board[i][j]==board[i+2][j-2] && board[i][j]==board[i+3][j-3])
            return 1;

//creates a typical 7 by 6 connect four board
    for (int i=0;i<numrows; i++){
        vector<string> row;

        for (int j=0;j<rowsize; j++)
            row.push_back(" ");
        board.push_back(row);
    }

Answer 1

我认为这可能是一个错误，因为评估所有电路板的电路板[i + x] [j + -y]将超出数组范围。

例如，当你有i = 4，j = 4时，第一个if语句将寻找电路板[4] [4]，电路板[5] [5]，电路板[6] [6]，电路板[7 ] [7]

检查连接4的win功能对角线是否正常工作
