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
for (int j = 0; 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：
