c++ - 如何移动二维指针数组中的行元素

Question

我有一个二维字符指针数组，其中包含一个大小为 7x7 的棋盘游戏。我的数组将如下所示:

我有我的代码将一列中的元素向上移动 1 个位置，如下所示:

void userMove(char **boardOfGame, int *sizeOfBoardGame, char typeOfUserTile, int userChoice)
{
    int countElement = 6;
    char tempElement;
    for (int i = 6; i > 0; i--)
    {
        if (!isspace(boardOfGame[i][userChoice]))
        {
            countElement--;
        }
    }
    if (typeOfUserTile == '+' || typeOfUserTile == '-' || typeOfUserTile == '|')
    {
        if (boardOfGame[userChoice][6] == 'X')
        {
            cout << "A locked tile is preventing your tile from being added. Try to be more careful next turn." << endl;
        }
        if (boardOfGame[6][userChoice] == ' ')
        {
            //boardOfGame[6][userChoice] = printf("\033[1;34m%c\033[0m\n",typeOfUserTile);
            boardOfGame[6][userChoice] = typeOfUserTile;
        }                   
        else if (boardOfGame[6][userChoice] == '+' || boardOfGame[6][userChoice] == '-' || boardOfGame[6][userChoice] == '|')
        {
            for (int i = countElement + 1; i > countElement; i--)
            {
                //memmove (&boardOfGame[i-1][userChoice], &boardOfGame[i][userChoice], 1);
                boardOfGame[i-1][userChoice] = boardOfGame[i][userChoice];
                if (i < 6 && i > 0)
                {
                    boardOfGame[i][userChoice] = boardOfGame[i + 1][userChoice];
                }           
                if (i == 0)
                {
                    boardOfGame[i][userChoice] = boardOfGame[i+1][userChoice];
                }
                boardOfGame[6][userChoice] = typeOfUserTile;                
            }
        }               
    }
}

它在前三行中工作正常，但在其余部分中存在问题。请帮我解决这个问题，我有点卡在这件事上了。什么都有帮助。谢谢。

很难准确地计算出您的代码功能(由于一些未使用的变量、重复的代码以及未使用短/单一职责功能)，无论如何很容易在所需列中向上移动矩阵:

const int rowSize = 7;
const int colSize = 7;

char scr[rowSize][colSize];

void shiftUp(int colInd)
{
    for (int r = 0; r < rowSize - 1; r++)
    {
        scr[r][colInd] = scr[r + 1][colInd];
    }
    scr[rowSize - 1][colInd] = '?';
}
