C語言 二維陣列實現三子棋的思路及程式碼

首先需要列印棋盤，用橫線和豎線去拼湊一個三行三列的棋盤

在這一步中需要用到for迴圈對二維陣列進行初始化，及將棋盤列印成型

棋盤列印出來後需要開始遊戲的進行，分為玩家的操作和電腦隨機生成的座標

在每次有人進行操作後都需要一個方法去判斷是否有人贏，或者是否棋盤滿了達到平局

完整程式碼如下

分為三個檔案（game.h,game.c,Tab.c）

<game.h>

void CmptMove(char board[][COL], int row, int col);
char IsWin(char board[][COL], int row, int col);
int IsFull(char board[][COL], int row, int col);
