Question

你能找到我的错误吗？程序编译，但运行时会崩溃并说出分段错误：第五行之后的11。该程序有3个文件。我正在制作一个国际象棋游戏，现在它应该做的就是打印棋盘。这就是它：

    cts/Software/Chess\ Game/a.out ; exit;
    setup complete
    rkb*qbkr
    pppppppp
    ________

    }

Answer 1

这样：

pieces[board_height][board_width] = NULL;

应该是这样的：

pieces[i][j] = NULL;

下次还要用-Wall编译它。它应该警告你我和j没有被使用。

国际象棋游戏：分段错误错误。你能找到吗？
