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; }}
