篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了带你玩转三子棋相关的知识，希望对你有一定的参考价值。
前言：所谓简易三子棋就是你和电脑下棋，当你和电脑其中有一方在棋盘中出现三行、三列或两条对角线有三个棋时，则那一方赢，接下来，就让我带你简单地操作一番。
1.设计主函数
int main() { test(); return 0; }我们所有的操作将会在test()函数中进行。
2.设计test函数
void test() { int input = 0; int srand = ((unsigned)time(NULL));//初始化随机数 do { menu();//最开始的菜单 printf("请选择："); scanf("%d", &input); switch (input) { case 1: game();//选择1进入游戏（游戏函数） break; case 2: printf("退出游戏！\\n"); break; default: printf("输入错误，请重新输入！"); break; } } while (input); }
3.打印菜单menu
void menu() { printf("************************\\n"); printf("****** 1.play ******\\n"); printf("****** 0.exit ******\\n"); printf("************************\\n"); }
4.进入游戏game
void game() { char board[ROW][COL] = { 0 }; Initboard(board, ROW, COL);//初始化棋盘 Displayboard(board, ROW, COL);//打印棋盘 int ret = 0; //下棋 while (1) { //玩家下棋 player_move(board, ROW, COL); Displayboard(board, ROW, COL);//每下一次就要打印棋盘 ret = is_win(board, ROW, COL);//判断是不是赢了 if (ret != 'C') { break; } //电脑下棋 computer_move(board, ROW, COL); Displayboard(board, ROW, COL);//每次电脑下棋也要记住并打印棋盘 ret = is_win(board, ROW, COL); //结果判断 // 玩家赢-‘*’ // 电脑赢-‘#’ // 继续-‘C’ //平局（也就是棋盘满了的时候）-‘Q’ if (ret != 'C')//判断结果是不是继续，不继续就代表出现了赢家 { break; } }
接下来就让我们来进行棋盘的初始化、棋盘的打印、下棋操作以及结果的判断
1.棋盘的初始化
Initboard(board, ROW, COL)
首先，我们要知道三子棋的棋盘长什么样，才能实现
棋盘的初始化需要每个格子都是空的，直接使用二维数组的初始化就可以实现
void Initboard(char board[ROW][COL], int row, int col) { int i = 0, j = 0; for (i = 0; i < row; i++) { for (j = 0; j < col; j++) { board[i][j] = ' '; } } }2.棋盘的打印
Displayboard(board, ROW, COL)
三子棋的棋盘由虚线和实线分割组成，所以我们要想办法先把分割线打印出来
void Displayboard(char board[ROW][COL], int row, int col) { int i = 0, j = 0, k = 0; for (i = 0; i < row; i++) { for (j = 0; j < col; j++) { printf(" %c ",board[i][j]);//每格的中间都是需要下棋的地方 if (j < col - 1) { printf("|");//分割线打印在每个格子的中间，最后一行的分割线不用打印 } } printf("\\n");//每打印一行进行换行 if (i < row - 1)//注意这里，棋盘最后一行的虚线分割线也不用打印 { for (j = 0; j < col; j++) { printf("---");// if (j < col - 1) { printf("|"); } } } printf("\\n"); } }3.玩家下棋
player_move(board, ROW, COL)
void player_move(char board[ROW][COL], int row, int col) { int x = 0, y = 0; printf("玩家走："); while (1) { scanf("%d %d", &x, &y);//玩家输入的坐标比二维数组的下标要小1 if (x >= 1 && x <= row && y >= 1 && y <= col)//判断玩家输入的坐标是否合法 { if (board[x - 1][y - 1] == ' ')//判断玩家输入的坐标是否被占用 { board[x - 1][y - 1] = '*'; break; } else { printf("该位置已被占用，请重新选择！"); } } else { printf("输入错误！"); } } }4.电脑下棋
computer_move(board, ROW, COL
void computer_move(char board[ROW][COL], int row, int col) { printf("电脑走：\\n"); int x = 0, y = 0; while (1) { x = rand() % ROW;//电脑输入的坐标由随机值产生 y = rand() % COL; if (board[x - 1][y - 1] == ' ')//电脑随机下棋，只要棋盘中哪里有空格就可以下哪里 { board[x - 1][y - 1] = '#'; break; } } }5.结果判断
is_win(board, ROW, COL)
赢得游戏有三种情况：
a.一行中连续出现了三颗一样的棋
b.一列中连续出现了三颗一样的棋
c.对角线连续出现了三颗一样的棋（而对角线又可以分成撇对角线和捺对角线）
int is_win(char board[ROW][COL], int row, int col) { //每行 int i = 0, j = 0; for (i = 0; i < row; i++) { for (j = 0; j < col-1; j++) { if (board[i][j] == board[i][j + 1] && board[i][j + 1] == board[i][j+2] && board[i][j]!=' ') return board[i][j]; } } //每列 i = 0; j = 0; for (j = 0; j < col; j++) { for (i = 0; i < row - 1; i++) { if (board[i][j] == board[i+1][j] && board[i + 1][j] == board[i+2][j] && board[i][j] != ' ') return board[i][j]; } } //捺对角线 i = 0; j = 0; for (i = 0; i < row; i++) { if (board[i][i] == board[i + 1][i + 1] && board[i + 1][i + 1] == board[i+2][j+2]&& board[i][i] != ' ') return board[i][i]; } //撇对角线 i = 0; j = 0; for (i = 0; i < row; i++) { for (j = col-1; j >= 0; j--) { if (board[i][j] == board[i + 1][j - 1] && board[i + 1][j - 1] == board[i+2][j-2] && board[i][j] != ' ') return board[i][j]; } } if (1 == is_full(board, ROW, COL))//判断棋盘是否满了 { return 'Q'; } else return 'C'; }6.判断棋盘是否已满
int is_full(char board[ROW][COL], int row, int col) { int i = 0, j = 0; for (i = 0; i < row; i++) { for (j = 0; j < col; j++) { if (board[i][j] == ' ')//有空格则没满，没满返回0 return 0; } } return 1;//满了返回1 }
以上就是我们对三子棋的基本实现
