思路

首先三子棋的规则是在3*3的棋盘上，三子连珠则为获胜，因此该游戏可以分为五个部分：电脑下棋，玩家下棋，棋盘判断，展示棋盘，棋盘初始化。

1. 电脑下棋：C语言学习初期，为了简单易编译，这里使用随机位置生成。
2. 玩家下棋：由玩家规定行列数，输入行列数下棋。
3. 棋盘判断：从行，列，斜对角线三个位置进行遍历判断，如果不满足胜利条件，就返回N继续进行。
4. 展示棋盘：将二维数组以棋盘形式输出。
5. 棋盘初始化：二维数组建立后，里面的值是不确定的，最好初始化为空格。

头文件创建

#ifndef _CHESS_H_
#define _CHESS_H_#include <stdio.h>
#include <Windows.h>
#include <time.h>#define ROW 3
#define COL 3
#define PLAYER_COLOR 'X'
#define COMPUTER_COLOR 'O'#pragma warning(disable:4996)void Game();
void InitBoard(char board[][COL], int row,int col);
void ShowBoard(char board[][COL], int row, int col);
void PlayerMove(char board[][COL], int row, int col);
char Judge(char board[][COL], int row, int col);
void ComputerMove(char board[][COL], int row, int col);#endif

菜单选择界面

#include "chess.h"void ShowMenu()
{printf("################################\n");printf("## 1.Play              2.Exit ##\n");printf("################################\n");printf("Please Select:");
}int main()
{int select = 0;int quit = 0;while (!quit) {ShowMenu();scanf("%d", &select);switch (select) {case 1:Game();break;case 2:printf("Bye be!\n");quit = 1;break;default:printf("select error,try again!\n");break;}}system("pause");return 0;
}

电脑下棋

void PlayerMove(char board[][COL], int row, int col)
{while (1) {int x = 0;int y = 0;printf("Please Enter Pos:");scanf("%d,%d", &x, &y);if (x >= 1 && x <= 3 && y >= 1 && y <= 3) {if (board[x - 1][y - 1] == ' ') {board[x - 1][y - 1] = PLAYER_COLOR;break;}else {printf("Enter Error,Try again!1\n");}}else {printf("Enter Error,Try again!2\n");}}
}

玩家下棋

void PlayerMove(char board[][COL], int row, int col)
{while (1) {int x = 0;int y = 0;printf("Please Enter Pos:");scanf("%d,%d", &x, &y);if (x >= 1 && x <= 3 && y >= 1 && y <= 3) {if (board[x - 1][y - 1] == ' ') {board[x - 1][y - 1] = PLAYER_COLOR;break;}else {printf("Enter Error,Try again!1\n");}}else {printf("Enter Error,Try again!2\n");}}
}

棋盘判断

char Judge(char board[][COL], int row, int col)
{int i = 0;for (; i < row; i++) {if(board[i][0] != ' ' && board[i][0] == board[i][1] && board[i][1]==board[i][2]){return board[i][0];}}for (i = 0; i < col; i++) {if (board[0][i] != ' ' && board[0][i] == board[1][i] && board[1][i] == board[2][i]){return board[0][i];}}if (board[0][0] != ' ' && board[0][0] == board[1][1] && board[1][1] == board[2][2]){return board[1][1];}if (board[0][2] != ' '&&board[0][2] == board[1][1] && board[1][1] == board[2][0]) {return board[1][1];}for (i = 0; i < row; i++) {int j = 0;for (; j < col; j++) {if (board[i][j] == ' ') {return 'N';}}}return 'E';
}

展示棋盘

void ShowBoard(char board[][COL], int row, int col)
{printf("   | 1 | 2 | 3\n");printf("----------------\n");int i = 1;for (; i <= 3; i++) {printf(" %d | %c | %c | %c \n", \i, board[i - 1][0], board[i - 1][1], board[i - 1][2]);if (i != 3) {printf("----------------\n");}}
}

棋盘初始化

void InitBoard(char board[][COL], int row, int col)
{int i = 0;for (; i < row; i++) {int j = 0;for (; j < col; j++) {board[i][j] = ' ';}}
}

游戏主程序

void Game()
{char board[ROW][COL];char result = 0;InitBoard(board,ROW,COL);ShowBoard(board, ROW, COL);while (1) {PlayerMove(board, ROW, COL);ShowBoard(board, ROW, COL);result = Judge(board, ROW, COL);if (result != 'N') {break;}ComputerMove(board, ROW, COL);ShowBoard(board, ROW, COL);result = Judge(board, ROW, COL);if (result != 'N') {break;}}switch (result) {case 'X'://you winprintf("你赢了\n");break;case 'O'://computer winprintf("你输了\n");break;case 'E'://Equalprintf("平局\n");break;default:printf("Throwable Exception?!?!\n");break;}printf("Play again?\n");
}
