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;}}
