本篇內容介紹了“怎么利用C語言實現AI五子棋游戲”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！
一.如何實現
二.實現代碼及分析
（1）菜單的制作
（2）棋盤的初始化和打印
（3）玩家下子
（4）電腦下子
（5）判斷輸贏
三.整個代碼
（1）test.c文件下代碼：
（2）game.c下的代碼
（3）game.h下的代碼
四.具體效果
1.棋盤打印以及選擇先后手
2.玩家和電腦下子
3.判斷輸贏
1.說明：由于本文只是對初學C語言的人學習，所以將不會涉及任何算法，電腦將采用隨機下子的方式。（后期會為大家介紹Alpha-Beta剪枝算法實現人工智能AI）
2.主要部分：
（1）菜單
（2）打印棋盤
（3）玩家下子
（4）電腦下子
（5）判斷輸贏
運用do…while循環調用菜單，根據用戶選擇實現玩游戲和退出游戲
棋盤采用標準的15*15的格子，我們可以宏定義ROW和COL分別為15和15來表示行和列。
分別封裝兩個函數對棋盤進行初始化和打印
初始化：（這里將棋盤初始化為空格，可初始化為其他）
打印棋盤：
效果如下：
void PlayerMove(char board[ROW][COL], int row, int col) {
int x, y;
while (1) {
printf("玩家走：\n");
printf("請輸入坐標：\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] = 'O';
break;
}
else {
printf("坐標被占用，請重新輸入\n");
}
}
else {
printf("坐標非法，請重新輸入\n");
}
}
}玩家下子主要采用的思路是，判斷棋盤上是否有子，已經輸入的坐標是否合法。
void ComputerMove(char board[ROW][COL], int row, int col) {
int x, y;
printf("電腦走\n");
while (1) {
x = rand() % row;
y = rand() % col;
if (board[x][y] == ' ') {
board[x][y] = 'X';
break;
}
}
}與玩家下子相同，此處采用的隨機下子，后期可進行優化（比如：極大極小值算法、Alpha-Beta剪枝算法等）
通過遍歷整個棋盤，觀察是否有連五子情況出現，代碼如下：
char iswin(char board[ROW][COL], int row, int col) {
//行
int ren=0,dian=0,i,j;
for (i = 0;i < row;i++) {
ren = 0;
for (j = 0;j < col;j++) {
if (board[i][j] == 'O')
ren++;
else
ren = 0;
if (ren >= 5)
return 'o';
}
}
for (i = 0;i < row;i++) {
dian = 0;
for (j = 0;j < col;j++) {
if (board[i][j] == 'X')
dian++;
else
dian = 0;
if (dian >= 5)
return 'x';
}
}
//列
ren = dian = 0;
for (i = 0;i < row;i++) {
ren = 0;
for (j = 0;j < col;j++) {
if (board[j][i] == 'O')
ren++;

}

此處我們看到玩家贏了，可是電腦實在太蠢了，所以還有很多地方需要添加的
