设计一个三子棋游戏

时间：2023-01-24 19:59:24

1.创建一个头文件，两个源文件

game.h中放包含的头文件和自定义函数的声明，game.c中放游戏的算法实现，test.h中放游戏逻辑地实现。

设计一个三子棋游戏

2.为游戏设计一个简单的菜单

void menu()
{
  printf("*********************\n");
  printf("***1.play   0.exit***\n");
  printf("*********************\n");
}

利用do ……while循环设计好游戏逻辑，当玩家输入“0”时，结果判定为假，跳出循环：输入“1”或非“0”时，结果判定为真，再次进入循环。

void test()
{
  int input = 0;
  do
  {
    menu();
    printf("请输入：>");
    scanf("%d/n", &input);
    switch (input)
    {
    case 1:
      game();
      break;
    case 0:
      printf("退出游戏\n");
      break;
    default:
      printf("选择错误，请重新选择\n");
      break;
    }
  } while (input);
}
int

3.打印棋盘，并将棋盘初始化

//初始化棋盘，变成空白
void IntiBoard(char board[ROW][COL], int row, int col)
{
  int i = 0;
  int j = 0;
  for (i = 0; i < row; i++)
  {
    for (j = 0; j < col; j++)
    {
      board[i][j] = ' ';
    }
  }
}

//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col)
{
  int i = 0;
  for (i = 0; i < row; i++)
  {
    int j = 0;
    for (j = 0; j < col; j++)
    {
      //打印一行数据
      printf(" %c ",board[i][j]);
      if (j < col - 1)
        printf("|");
    }
    printf("\n");
    //打印分隔行
    if (i < row - 1)
    {
      for (j = 0; j < col; j++)
      {
        printf("---");
        if (j < col - 1)
          printf("|");
      }
    }
    printf("\n");
  }
}

玩家下棋

数组下标从0开始，但没学过编程的人一般从1开始，所以后面要减1

void PlayerMove(char board[ROW][COL], int row, int col)
{
  int x = 0;
  int y = 0;
  printf("玩家走:>\n");
  while (1)
  {
    printf("请输入要下的坐标:>");
    scanf("%d %d", &x, &y);
    //判断坐标合法性
    if (x >= 1 && x <= row && y >= 1 && y <= col)
    {
      if (board[x - 1][y - 1] == ' ')
      {
        board[x - 1][y - 1] = '*';
        break;
      }
      else
      {
        printf("坐标被占用\n");
      }
    }
    else
    {
      printf("坐标非法，请重新输入:>\n");
    }
  }
}

电脑下棋

void ComputerMove(char board[ROW][COL], int row, int col)
{
  int x = 0;
  int  y = 0;
  printf("电脑走:>\n");
  while (1)
  {
    x = rand() % row;
    y = rand() % col;
    if (board[x][y] == ' ')
    {
      board[x][y] = '#';
      break;
    }
  }
}

判断输赢

//玩家赢   '*'

//电脑赢   '#'

//平局     'Q'     棋盘满了

//继续     'C'

//返回1棋盘满了
//返回0棋盘没满
int  IsFull(char board[ROW][COL], int row, int col)
{
  int i = 0;
  int j = 0;
  for (i = 0; i < row; i++)
  {
    for (j = 0; j < col; j++)
    {
      if (board[i][j] == ' ')
      {
        return 0;
      }
    }
  }
  return 1;   //满了
}



char IsWin(char board[ROW][COL], int row, int col)
{
  int i = 0;
  //判断三行
  for (i = 0; i < row; i++)
  {
    if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ')
    {
      return board[i][1];
    }
  }
  //判断三列
  for (i = 0; i < col; i++)
  {
    if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
    {
      return board[1][i];
    }
  }
  //判断对角线
  if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
  {
    return board [1][1];
  }
  if (board[2][0] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
  {
    return board[1][1];
  }
  //判断平局
  if (1 == IsFull(board, ROW, COL))
  {
    return 'Q';
  }
  return 'C';
}
