在迷宫中标记路径

Question

我试图在迷宫中标记路径。我被困在这一点上。它只标记一个向右的方向。但我写出来的位置是X = 1 Y = 2。真的很奇怪。我的想法是为if语句创建一个while循环但是if语句甚至没有运行..请给我一些想法。

if (strcmp(argv[1], "-input") == 0)
{
    ifstream ifs(argv[2]);
    if(!ifs)
    {
        cout << "Felaktig textfil";
    }
    vector<vector<char>> maze;
    vector<vector<char>> path;
    string line;
    unsigned int j=0;
    while (!ifs.eof())
    {
        getline(ifs, line);
        maze.push_back(vector<char>());
        for (int i=0; i < line.size(); i++)
        {
            maze[j].push_back(line[i]);
        }
        j++;
    }
    //cout << maze.size();
    int startX,startY;

    for (int i = 0; i < maze.size(); i++)
    {
        for (int j = 0; j < maze[i].size(); j++)
        {
            if (maze[i][j] == 'S')
            {
                startX = j;
                startY = i;
                break;
            }
        }
    }
    if (startX + 1 < maze.size() && maze[startX + 1][startY] != '*')
    {
        startX++;
        maze[startY][startX]='x';
    }

    if (startX - 1 > 0 && maze[startX - 1][startY] != '*')
    {
        startX++;
        maze[startY][startX] = 'x';
    }

    if (startY - 1 > 0 && maze[startX][startY - 1] != '*')
    {
        startY--;
        maze[startY][startX] = 'x';
    }
    if (startY + 1 < maze.size() && maze[startX][startY + 1] != '*')
    {
        startY++;
        maze[startY][startX]='x';
    }
    if (maze[startY][startX]=='X')
    {
        cout << "done";
    }
    cout << startX <<startY << endl;

    PrintMaze(maze);
}
