这篇文章主要为大家展示了“C语言如何开发实现井字棋”，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下“C语言如何开发实现井字棋”这篇文章吧。
总体思路
井字棋棋盘我们总体可以当成一个二维数组来操作，我们分别需要实现初始化二维数组，打印棋盘，玩家下棋，电脑下棋，判断输赢等代码
项目的创建
我们创建了头文件用于放函数的声明，game.c文件放置函数的实现，test.c文件用于测试。
测试结果
电脑获胜：
玩家获胜：
平局：
各函数代码的实现
我们在game.c文件中实现函数功能的代码
初始化二维数组
void InitBoard(char Board[ROW][COL], int row, int col){for (int i = 0; i < row; i++){for (int j = 0; j < col; j++){Board[i][j] = ' ';}}}打印棋盘
void DisplayBoard(char Board[ROW][COL], int row, int col){for (int i = 0; i < row; i++){for (int j = 0; j < col; j++){printf(" %c ", Board[i][j]);if (j < col - 1)printf("|");}printf("\n");if (i < row - 1){for (int j = 0; j < col; j++){printf("---");if (j < col - 1)printf("|");}}printf("\n");}}这里的棋盘我们只打印了井字的形状，如果为了美观，还可以进行封边，这里就留给朋友们自行实现啦。
玩家下棋
void PlayMove(char Board[ROW][COL], int row, int col){while (1){int x = 0, y = 0;printf("请输入坐标：\n");scanf("%d%d", &x, &y);if (x >= 1 && x <= row && y >= 1 && y <= col){if (Board[x - 1][y - 1] == ' '){Board[x - 1][y - 1] = '#';break;}elseprintf("该位置已被占，请重新输入：\n");}else{printf("输入错误，请重新输入：\n");}}}电脑下棋
在电脑落子之前，先检测有没有下一步可以直接赢的，若有，则落子在此处，电脑获胜，若没有，再检测玩家下一步是否有机会获胜，若玩家下一步可以直接获胜，那么电脑将抢占这一步。
如果上述两种情况均不存在，当发现(1，1)位置是空时，电脑先下这一步。
其他情况均随意落子。
void ComputerMove(char Board[ROW][COL], int row, int col){int x = 0, y = 0;while (1){if (JudgeComputer(Board, ROW, COL)){for (int i = 0; i < row; i++){if (Board[i][0] == Board[i][1] && Board[i][0] == '*' && Board[i][2] == ' '){Board[i][2] = '*';return;}else if (Board[i][0] == Board[i][2] && Board[i][0] == '*' && Board[i][1] == ' '){Board[i][1] = '*';return;}else if (Board[i][1] == Board[i][2] && Board[i][1] == '*' && Board[i][0] == ' '){Board[i][0] = '*';return;}}for (int j = 0; j < col; j++){if (Board[0][j] == Board[1][j] && Board[0][j] == '*' && Board[2][j] == ' '){Board[2][j] = '*';return;}else if (Board[0][j] == Board[2][j] && Board[0][j] == '*' && Board[1][j] == ' '){Board[1][j] = '*';return;}else if (Board[1][j] == Board[2][j] && Board[1][j] == '*' && Board[0][j] == ' '){Board[0][j] = '*';return;}}if (Board[0][0] == Board[1][1] && Board[0][0] == '*' && Board[2][2] == ' '){Board[2][2] = '*';return;}else if (Board[0][0] == Board[2][2] && Board[0][0] == '*' && Board[1][1] == ' '){Board[1][1] = '*';return;}else if (Board[1][1] == Board[2][2] && Board[1][1] == '*' && Board[0][0] == ' '){Board[0][0] = '*';return;}else if (Board[0][2] == Board[1][1] && Board[0][2] == '*' && Board[2][0] == ' '){Board[2][0] = '*';return;}else if (Board[0][2] == Board[2][0] && Board[0][2] == '*' && Board[1][1] == ' '){Board[1][1] = '*';return;}else if (Board[2][0] == Board[1][1] && Board[2][0] == '*' && Board[0][2] == ' '){Board[0][2] = '*';return;}}else if (JudgePlayer(Board, ROW, COL)){for (int i = 0; i < row; i++){if (Board[i][0] == Board[i][1] && Board[i][0] == '#' && Board[i][2] == ' '){Board[i][2] = '*';return;}else if (Board[i][0] == Board[i][2] && Board[i][0] == '#' && Board[i][1] == ' '){Board[i][1] = '*';return;}else if (Board[i][1] == Board[i][2] && Board[i][1] == '#' && Board[i][0] == ' '){Board[i][0] = '*';return;}}for (int j = 0; j < col; j++){if (Board[0][j] == Board[1][j] && Board[0][j] == '#' && Board[2][j] == ' '){Board[2][j] = '*';return;}else if (Board[0][j] == Board[2][j] && Board[0][j] == '#' && Board[1][j] == ' '){Board[1][j] = '*';return;}else if (Board[1][j] == Board[2][j] && Board[1][j] == '#' && Board[0][j] == ' '){Board[0][j] = '*';return;}}if (Board[0][0] == Board[1][1] && Board[0][0] == '#' && Board[2][2] == ' '){Board[2][2] = '*';return;}else if (Board[0][0] == Board[2][2] && Board[0][0] == '#' && Board[1][1] == ' '){Board[1][1] = '*';return;}else if (Board[1][1] == Board[2][2] && Board[1][1] == '#' && Board[0][0] == ' '){Board[0][0] = '*';return;}else if (Board[0][2] == Board[1][1] && Board[0][2] == '#' && Board[2][0] == ' '){Board[2][0] = '*';return;}else if (Board[0][2] == Board[2][0] && Board[0][2] == '#' && Board[1][1] == ' '){Board[1][1] = '*';return;}else if (Board[2][0] == Board[1][1] && Board[2][0] == '#' && Board[0][2] == ' '){Board[0][2] = '*';return;}}else{if (Board[1][1] == ' '){Board[1][1] = '*';return;}else{x = rand() % row;y = rand() % col;if (Board[x][y] == ' '){Board[x][y] = '*';break;}}}}}判断电脑是否有位置可以获胜

我们在game.h头文件中进行函数的声明。
void meun();#define ROW 3#define COL 3//游戏主函数void game();//初始化二维数组void InitBoard(char Board[ROW][COL], int row, int col);//打印棋盘void DisplayBoard(char Board[ROW][COL], int row, int col);//玩家下棋void PlayMove(char Board[ROW][COL], int row, int col);//电脑下棋void ComputerMove(char Board[ROW][COL], int row, int col);//判断赢否char IsWin(char Board[ROW][COL], int row, int col);//判断棋盘满了吗//int IsFull(char Board[ROW][COL], int row, int col);//判断电脑下一部是否可以直接赢//int JudgeComputer(char Board[ROW][COL], int row, int col);//判断玩家下一步是否会赢//int JudgePlayer(char Board[ROW][COL], int row, int col);测试代码
我们在test.c文件中测试该游戏。
#include "game.h"void game(){char ret = 0;char Board[ROW][COL] = { 0 };//初始化数组InitBoard(Board, ROW, COL);//打印棋盘printf("棋盘如下：\n");DisplayBoard(Board, ROW, COL);while (1){//玩家下棋printf("玩家落子：\n");PlayMove(Board, ROW, COL);//每下一步打印一次棋盘DisplayBoard(Board, ROW, COL);//每下一步判断一次胜负ret = IsWin(Board, ROW, COL);if (ret != 'C'){break;}//电脑下棋printf("电脑落子：\n");ComputerMove(Board, ROW, COL);//每下一步打印一次棋盘DisplayBoard(Board, ROW, COL);ret = IsWin(Board, ROW, COL);if (ret != 'C'){break;}}if (ret == '#')printf("玩家获胜\n");else if (ret == '*')printf("电脑获胜\n");else if (ret == 'o')printf("卧龙凤雏\n");}void test(){int input = 0;srand((size_t)time(NULL));do{meun();printf("请选择:>");scanf("%d", &input);switch (input){case 1:game();break;case 0:printf("游戏结束\n");break;default:printf("输入错误，请重新输入：\n");break;}} while (input);}int main(){test();return 0;}以上是“C语言如何开发实现井字棋”这篇文章的所有内容，感谢各位的阅读！相信大家都有了一定的了解，希望分享的内容对大家有所帮助，如果还想学习更多知识，欢迎关注编程网行业资讯频道！
