1、创建2个.c文件分别为text.c和game.c和一个头文件game.h

text.c代码如下：

#include "game.h"
void game() {//存储数组 - 二维数组char board[ROW][COL];//初始化棋盘InitBoard(board, ROW, COL);//打印棋盘 - 就是打印数组DisplayBoard(board,ROW,COL);char ret = 0;while (1) {//玩家走PlayerMove(board,ROW,COL);DisplayBoard(board, ROW, COL);ret = IsWin(board, ROW, COL);if (ret != 'c') {break;}ComputerMove(board, ROW, COL);DisplayBoard(board, ROW, COL);ret = IsWin(board, ROW, COL);if (ret != 'c') {break;}//电脑走} if (ret == '*') {printf("玩家贏了\n");}else if (ret == '#') {printf("电脑赢了\n");}else {printf("平局\n");}DisplayBoard(board, ROW, COL);
}void menu() {printf("################################\n");printf("########1、开始游戏#############\n");printf("########0、退出游戏#############\n");printf("################################\n");
}int main()
{int input = 0;srand((unsigned int)time(NULL));do {menu();printf("请选择");scanf("%d", &input);switch (input) {case 1:game();break;case 0:printf("退出游戏");break;default:printf("请选择菜单中有的项");break;}} while (input);return 0;
}

game.c文件代码如下：

#define _CRT_SECURE_NO_WARNINGS 1#include "game.h"
void InitBoard(char board[ROW][COL], int row, int col)
{int i = 0;int j = 0;for (i = 0; i < row; i++) {for (j = 0; j < col; j++) {board[i][j] = ' ';}}
}
//
//void DisplayBoard(char board[ROW][COL], int row, int col) {
//	int i = 0;
//	for (i = 0; i < row; i++) {
//		printf("%c  | %c | %c \n", board[i][0], board[i][1], board[i][2]);
//		if (i < row - 1) {
//			printf("---|---|---\n");
//		}
//	}
//}void DisplayBoard(char board[ROW][COL], int row, int col) {int i = 0;for (i = 0; i < row; i++) {int j = 0;for (j = 0; j < col; j++) {printf(" %c ",board[i][j]);if (j < col - 1) {printf("|");}}printf("\n");if (i < row - 1) {int j = 0;for (j = 0; j < col; j++) {printf("---");if (j < col - 1) {printf("|");}}printf("\n");}}
}void PlayerMove(char board[ROW][COL], int row, int col)
{int x = 0;int y = 0;printf("玩家走：\n");while (1) {printf("请输入下棋的坐标");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;}else {printf("坐标已经输入");}}else {printf("坐标非法，请重新输入");}}}//
void ComputerMove(char board[ROW][COL], int row, int col)
{printf("电脑走：\n");while (1) {int x = rand() % row;int y = rand() % col;if (board[x][y]==' ') {board[x][y] = '#';break;}}
}int Isfull(char board[ROW][COL], int row, int col) {int i = 0;int j = 0;for (i = 0; i < row; i++) {for (j = 0; j < col; j++) {if (board[i][j] == ' ') {return 0;}}}return 1;
}char IsWin(char board[ROW][COL], int row, int col) {int i = 0;//判断三行for (i = 0; i < row; i++) {if (board[i][0] == board[i][1] && board[i][1]== board[i][2] && board[i][1] != ' ') {return board[i][1];}}//判断三列for (i = 0; i < col; i++) {if (board[0][i] == board[1][i] && board[1][i]== board[2][i] && board[1][i] != ' ') {return board[1][i];}}//判断对角线if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ') {return  board[1][1];}if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ') {return board[1][1];}//判断平局int ret = Isfull(board, row, col);if (ret == 1) {return 'q';}return 'c';
}

game.h文件代码如下:

#pragma once
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ROW 3
#define COL 3//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col);void PlayerMove(char board[ROW][COL], int row, int col);void ComputerMove(char board[ROW][COL], int row, int col);char IsWin(char board[ROW][COL], int row, int col);
