八月初心血来潮，花了一天时间写了一个控制台版的2048。代码很烂，玩到后面会有延迟现象。先做下记录，以后有时间把移动和合并的代码再优化下。
代码如下：
1 #include<iostream> 2 #include <iomanip> 3 #include<cstring> 4 #include<cstdlib> 5 #include<ctime> 6 using namespace std; 7 8 class Board { 9 public: 10 int board[4][4]; //棋盘数组 11 int n; //已存在数字个数 12 Board(); //构造函数 13 void randx(); //随机生成数字2/4 14 void print(); //打印棋盘 15 bool check(); //检查是否GameOver 16 bool up(); //向上操作 17 bool down(); //向下操作 18 bool left(); //向左操作 19 bool right(); //向右操作 20 }; 21 22 Board::Board() //构造函数 23 { 24 memset(board,0,sizeof(board)); //初始化为0 25 n=0; 26 } 27 void Board::randx() //随机生成数字2/4 28 { 29 while(true) 30 { 31 srand(time(NULL)); 32 int x=rand()%16; //产生随机次序 33 if(board[x/4][x%4]==0) 34 { 35 srand(time(NULL)); 36 board[x/4][x%4]=rand()%2==0?2:4;
