2048源代码~~小游戏。C++实现

每一个学习软件工程的人，都很想自己写出游戏的代码，我也不例外，但是，能写出一些小游戏的代码，并不能说明你很厉害，而只能说明你对于这门语言你比较熟悉了。

2048这个游戏，是一两年前很火的游戏，不过现在也没什么人在玩了，闲来没事，就写了一下这个游戏，控制台上实现的，目前我还不会写窗口，所以很多东西都只能在控制台上来实现了。

2048这个小游戏，主要的是上下左右移动后，相同的数合并，不相同的数原样输出，而你就是要判断每一行或每一列有没有相同的，还有一点就是，数字有移动，就产生新的数，没有，什么都不用做。

下面是头文件的：

class New2048{public:New2048()                       //构造函数，初始话数据。{ for (int i = 0; i < 4; i++)for (int j = 0; j < 4; j++)a[i][j] = 0;num = 0;}void make_frame();             //打印框架函数。void display_num();            //打印数字函数。void creat_num();              //随机产生数函数void RightMove();              //右移函数void LeftMove();               //左移函数void UpMove();       //上移函数void DownMove();       //下移函数int cheak();                   //检查游戏是否结束函数void clean();                  //清理显示出来的数字~New2048(){}private:int a[4][4];int num;};

下面是各个函数的cpp文件：
