如何用C语言来实现三子棋（井字棋），供大家参考，具体内容如下
大致思路如下
1.先打印出菜单供用户进行游戏还是退出游戏2.编写打印棋盘的函数3.编写用户和电脑下棋的函数4.最后对玩家或用户下棋后进行判断输赢
贴张胜利的图片
实现打印菜单的函数
void menu(){ printf("******************************************\n"); printf("************* 1. play *************\n"); printf("************* 2.exit *************\n"); printf("******************************************\n");}
主函数的实现
int main(){ int input; srand((unsigned int)time(NULL)); do { menu(); printf("请选择>"); scanf("%d", &input); switch (input) { case 0: printf("退出\n"); break; case 1: game(); break; default: printf("输入错误，"); break; } } while (input); return 0;}
根据用户的选择是玩游戏还是退出，玩完一局后也可以在玩一局
game函数的实现
void game(){ char board[ROW][COL]; //初始化棋盘 InitBoard(board, ROW, COL); //打印棋盘 PrinBoard(board, ROW, COL); char flag = 0; //下棋 while (1) { PlayMove(board, ROW, COL); PrinBoard(board, ROW, COL); //判断当前状态 flag = IsWin(board, ROW, COL); if (flag != 'c') break; //电脑下棋 CompMove(board, ROW, COL); PrinBoard(board, ROW, COL); //判断当前状态 flag = IsWin(board, ROW, COL); if (flag != 'c') break; } if (flag == '*') printf("恭喜玩家获胜\n"); else if (flag == '#') printf("恭喜电脑获胜\n"); else printf("平局啦\n");}
在每次玩家或电脑下完棋后都应该进行判断，判断当前棋盘的状态.
打印棋盘
首先应先打印棋盘，而且在每次下完棋后也应在打印一下棋盘
void PrinBoard(char board[ROW][COL], int row, int col){ int i = 0; for (i = 0; i < row; i++) { int j = 0; for (int j = 0; j < col; j++) { printf(" %c ", board[i][j]); if (j < col - 1) printf("|"); } printf("\n"); if (i < row - 1) { for (j = 0; j < col; j++) { printf("---"); if (j < col - 1) printf("|"); } } printf("\n"); }}
判断函数
IsWin函数应该有四种状态分别为：玩家赢（*）、电脑赢（#）、平局（d)和继续©。
char IsWin(char board[ROW][COL], int row, int col){ int i = 0; //判断行 for (i = 0; i < row; i++) { int j = 0; for (j = 0; j < col - 1; j++) { if (board[i][j] == ' ' || board[i][j] != board[i][j + 1]) break; } if (j == col - 1) return board[i][j - 1]; } //判断列 for (i = 0; i < col; i++) { int j = 0; for (j = 0; j < row - 1; j++) { if (board[j][i] == ' ' || board[j][i] != board[j + 1][i]) break; } if (j == row - 1) return board[j][i]; } //右斜 for (i = 0; i < row - 1; i++) { if (board[i][i] == ' ' || board[i][i] != board[i + 1][i + 1]) break; } if (i == row - 1) return board[i][i]; int x = 1, y = col - 2; while (x < row&&y >= 0) { if (board[x][y] == ' ' || board[x][y] != board[x - 1][y + 1]) break; x++; y--; } if (x == row && y < 0) return board[x - 1][y + 1]; //判断是否平局 for (i = 0; i < row; i++) { int j = 0; for (j = 0; j < col; j++) { if (board[i][j] == ' ') return 'c'; } } //平局 return 'd';}
下棋函数
电脑下棋时通过时间戳来生成随机数，并判断当前位置是否合法。每次下完棋后应该对棋盘进行判断，通过调用函数IsWin根据返回值，判断是继续还是跳出。
void PlayMove(char board[ROW][COL], int row, int col){ printf("请玩家下棋>"); while (1) { int x, y; printf("输入您要下的位置"); scanf("%d %d", &x, &y); if (x >= 1 && x <= row && y >= 1 && y <= col) { //判断当前位置是否有棋子 if (board[x - 1][y - 1] == ' ') { board[x - 1][y - 1] = '*'; break; } else printf("此位置重复\n"); } else printf("此坐标不合法，超出棋盘大小\n"); }}void CompMove(char board[ROW][COL], int row, int col){ printf("电脑下棋>\n"); printf("\n"); while (1) { int x = rand() % row; int y = rand() % col; if (board[x][y] == ' ') { board[x][y] = '#'; break; } }}
到这各个函数的实现已完成。
