I'm trying to read a text file with a 12x12 ASCII maze in it. However, all I'm getting on the screen is a 12x12 grid of asterisks.

I used similar code in a CLI minesweeper game I coded last semester and it worked fine. I'm not sure what I've done to cause it to not work...

Code:

bool loadBoard(Tile board [][gridSize], string filename) {
    ifstream hndl;
    char isWall;
    hndl.open(filename);

    // Check that the file is opened
    if (hndl.is_open()) {
        for (int row = 0; row < gridSize; row++) {
            for (int col = 0; col < gridSize; col++) {
                hndl >> isWall;

                if (isWall == '*')
                    board[row][col].wall = true;

                cout << row << col << isWall << " ";
            }
            cout << endl;
        }
    }

    return EXIT_SUCCESS;
}

File maze.txt:

************

Output:

有帮助吗?

解决方案

Your code "skips" any whitespace. You can do cin >> noskipws >> isWall; - or you could use a different character to show "not wall", such as '.' or '-'.

其他提示

>> operator ignores whitespace characters, that's why it skips over the blanks and always consumes an asterix. Use std::istream.get() instead.
