一个用C++编程的小游戏，可以实现的功能如下：
1、随机生成数字；
2、数字消除合并；
3、判定游戏结束；
一、游戏主体：
因为用C++写的，所以用了类，棋盘用了一个二维数组，m是棋盘规格，取了4。
class game
{
public:
int i, j;
game() {
count1 = 0;
for (i = 0; i < m; i++)
for (j = 0; j < m; j++)
chessboard[i][j] = 0;
srand((unsigned)time(NULL));
x = rand() % m;
y = rand() % m;
if (count1 == 1 || count1 == 0)
chessboard[x][y] = 2;
else
chessboard[x][y] = 4;
showchessboard();
}//构造初始棋盘
void add(int count1);//新增数字
void showchessboard();//显示棋盘
void up();
void down();
void left();
void right();
bool gameover();//游戏失败
private:
int chessboard[m][m];
int x, y, count1, count2, temp1, temp2, k;//c1-连消，c2-空位标记，t1-判连消，t2,k-临时变量
bool flag;//判消
};
二、随机生成数字
void game::add(int count1)
{
for (i = 0; i < m; i++)
for (j = 0; j < m; j++)
{
if (chessboard[i][j] == 0)
goto loop;
}
showchessboard();
return;
loop:srand((unsigned)time(NULL));
do {
x = rand() % m;
y = rand() % m;
} while (chessboard[x][y] != 0);
if (count1 < 2)
chessboard[x][y] = 2;
else
chessboard[x][y] = 4;
showchessboard();
}
三、数字消除合并
void game::up()
{
temp1 = count1;
flag = false;
for (j = 0; j < m; j++)
for (i = 0; i < m;)
{
for (; i < 4 && chessboard[i][j] == 0; i++); // 找非零值
if (i == 4)
break;
else
{
for (k = i + 1; k < 4 && chessboard[k][j] == 0; k++);//找下一个非零值
if (k == 4)
break;
else if (chessboard[i][j] == chessboard[k][j])//匹配
{
chessboard[i][j] *= 2;
chessboard[k][j] = 0;
i = k + 1;
flag = true;
}
else if (chessboard[i][j] != chessboard[k][j] && k < 4)//不匹配
{
i = k;
}
}
}
for (j = 0; j < m; j++)//排列棋盘
for (i = 0, count2 = 0; i < m; i++)
{
if (chessboard[i][j] != 0)
{
temp2 = chessboard[i][j];
chessboard[i][j] = 0;
chessboard[count2][j] = temp2;
count2++;
}
}
}
四、判断游戏结束
bool game::gameover()
{
if (flag)
count1++;//判连消
if (temp1 == count1)
count1 = 0;//未消除，连消归零
add(count1);
for (i = m - 1, j = 0; j < m; j++)//最后一行
{
if (j == m - 1)//右下角
{
if (chessboard[i][j] == 0)
return false;
else if (chessboard[i][j] == 2048)
{
cout << "You Win~
";
return true;
}
}
else
{
if (chessboard[i][j] == 0 || chessboard[i][j] == chessboard[i][j + 1])
return false;
else if (chessboard[i][j] == 2048)
{
cout << "You Win~
";
return true;
}
}
}
for (i = 0, j = m - 1; i < m; i++)//最后一列
{
if (i == m - 1)//右下角
{
if (chessboard[i][j] == 0)
return false;
else if (chessboard[i][j] == 2048)
{
cout << "You Win~
";
return true;
}
}
else
{
if (chessboard[i][j] == 0 || chessboard[i][j] == chessboard[i + 1][j])
return false;
else if (chessboard[i][j] == 2048)
{
cout << "You Win~
";
return true;
}
}
}
for (i = 0; i < m - 1; i++)
for (j = 0; j < m - 1; j++)
{
if (chessboard[i][j] == 2048)
{
cout << "You Win!
";
return true;
}
else if (chessboard[i][j] == chessboard[i][j + 1] || chessboard[i][j] == chessboard[i + 1][j] || chessboard[i][j] == 0)
return false;
}
cout << "Game over.
";
return true;
}
扩展资料：
C++语言的程序因为要体现高性能，所以都是编译型的。但其开发环境，为了方便测试，将调试环境做成解释型的。
生成程序是指将源码（C++语句）转换成一个可以运行的应用程序的过程。如果程序的编写是正确的，那么通常只需按一个功能键，即可搞定这个过程。但是该过程实际上分成两个步骤。
第一步是对程序进行编译，这需要用到编译器（compiler）。编译器将C++语句转换成机器码(也称为目标码)；
第二步就是对程序进行链接，这需要用到链接器（linker）。链接器将编译获得机器码与C++库中的代码进行合并。C++库包含了执行某些常见任务的函数（“函数”是子程序的另一种称呼）。
