用C语言实现三子棋

本文实例为大家分享了用C语言实现三子棋的具体代码，供大家参考，具体内容如下

三子棋含义：

三子棋是黑白棋的一种。三子棋又叫九宫棋、圈圈叉叉、一条龙、井字棋等。将正方形对角线连起来，相对两边依次摆上三个双方棋子，只要将自己的三个棋子走成一条线，对方就算输了。但是，有很多时候会出现和棋的情况。图例如下：

基本思路：

1.创建用户交互菜单界面

2.初始化棋盘

3.显示棋盘面板（为了不重复显示棋盘，使用清屏操作）

4.用户落子

5.判断胜负

6.电脑随机正确落子

7.判断胜负

（在每次写程序之前，可以向如下图所示，写出思路或伪代码）

创建多文件项目：

写代码之前，首先建立三个文件，以方便后序代码更加完整清晰地呈现。

1.创建用户交互菜单界面

void Meau(){
 printf("+------ meau ----------+\n");
 printf("|----  1.play  --------|\n");
 printf("|----  0.quit  --------|\n");
 printf("+----------------------+\n");
}

2.初始化棋盘

使用宏定义，将棋盘中的内容初始化为空。

static void InitBoard(char board[][COL], int row, int col){
 for (int i = 0; i < row; i++){
  for (int j = 0; j < col; j++){
   board[i][j] = INIT;
  }
 }
}

3.显示棋盘面板

为了不重复显示棋盘，使用清屏操作，使得每次现实的棋盘只有一张。

通过不断调试，使得最终界面，与预期所需界面一致。

static void ShowBoard(char board[][COL],int row,int col){
 system("cls");//清屏操作
 printf("  ");
 for (int i = 0; i < col; i++){
  printf(" %3d", i + 1);
 }
 printf("\n----------------\n");
 for (int i = 0; i < row; i++){
  printf("%-2d", i + 1);
  for (int j = 0; j < col; j++){
   printf("| %c ", board[i][j]);
  }
  printf("\n----------------\n");
 }
}

4.用户落子

落子只能落在为空的位置上，所以在落子前需要判空，若为空，则落子，否则提示重新落子。

static void PlayerMove(char board[][COL], int row, int col){
 int x = 0;
 int y = 0;
 while (1){
  printf("please enter your postion<x,y>: ");
  scanf("%d %d", &x, &y);
  if (x<1 || x>3 || y<1 || y>3){
   printf("Postion Error!");
   continue;
  }
  if (board[x - 1][y - 1] == INIT){
   board[x - 1][y - 1] = WHITE;
   break;
  }
  else{
   printf("Postion Is Not Empty!\n");
  }
 }
}

5.电脑随机正确落子

使用随机数，在正确位置落子。

static void ComputerMove(char board[][COL], int row, int col){
 while (1){
  int x = rand() % row;
  int y = rand() % col;
  if (board[x][y] == INIT){
      board[x][y] = BLACK;
   break; 
  }
 }
}

6.判断胜负

static char IsEnd(char board[][COL], int row, int col){
 for (int i = 0; i < row; i++){
  if (board[i][0] == board[i][1] && \
   board[i][1] == board[i][2] && \
   board[i][0] != INIT){
   return board[i][0];
  }
 }
 for (int j = 0; j < col; j++){
  if (board[0][j] == board[1][j] && \
   board[1][j] == board[2][j] && \
   board[0][j] != INIT){
   return board[0][j];
  }
 }
 if (board[0][0] == board[1][1] && \
  board[1][1] == board[2][2] && \
  board[0][0] != INIT){
  return board[0][0];
 }
 if(board[0][2] == board[1][1] && \
  board[1][1] == board[2][0] && \
  board[1][1] != INIT){
  return board[1][1];
 }
 for (int i = 0; i < row; i++){
  for (int j = 0; j < col; j++){
   if (board[i][j] == INIT);
   return NEXT;
  }
 }
 return DRAW;
}

7.创建Game界面

void Game()
{
 char board[ROW][COL];
 InitBoard(board, ROW, COL);
 srand((unsigned long)time(NULL));
 char result = 0;
 while (1){
  ShowBoard(board, ROW, COL);
  PlayerMove(board, ROW, COL);
  result = IsEnd(board, ROW, COL);
  if (result != NEXT){
   break;
  }
 
 ShowBoard(board, ROW, COL);
 ComputerMove(board, ROW, COL);
 result = IsEnd(board, ROW, COL);
 
 if (result != NEXT){
  break;
     }
 }
 ShowBoard(board, ROW, COL);
 switch (result){
 case WHITE:
  printf("You win!\n");
  break;
 case BLACK:
  printf("you lose!\n");
  break;
 case DRAW:
  printf("it ends in a draw\n"); 
  break;
 defult:
  printf("bug\n");
  break;
 }
}
