程序中使用了一个二维数组 `board` 来表示2048游戏的棋盘，其中每个元素代表棋盘上的一个格子，初始值为0。`generate_random_number` 函数用来生成一个随机数，`generate_new_number` 函数用来在空格子上生成一个新的数字。`move_left`、`move_right`、`move_up`、`move_down` 函数分别用来实现向左、向右、向上、向下移动格子的操作。`check_game_over` 函数用来检查游戏是否结束。

在 `main` 函数中，程序先初始化棋盘，生成两个初始数字，并输出棋盘。然后进入循环，每次循环中用户输入一个操作，程序根据用户的选择更新棋盘，并检查游戏是否结束。如果游戏没有结束，则生成一个新的数字并输出棋盘。如果游戏结束，程序退出循环并输出 "Game over!"。
