基本框架
三个文件:
需要用到的头文件：
#include <stdio.h>
#include <stdlib.h>//rand&srand
#include <time.h>//时间相关框架运行
#include"game.h"
void menu()
{
printf("*********************************\n");
printf("******** 1. play ********\n");
printf("******** 0. exit ********\n");
printf("*********************************\n");
}
void game()
{
}
int main()
{
int input;
do
{
menu();
printf("请选择:>");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("退出游戏\n");
break;
default:
printf("选择错误，重新选择!\n");
break;
}
}
while (input);
return 0;
}运行结果：
棋盘
#define COL 3
#define ROW 3打印：
初始化函数
void init_board(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] = ' ';
}
}
}
可以发现这次棋盘很标准了，但有点刻意的风味，如果想要一个10*10的棋盘，又要重新设计吗？应对此种情况，我们试着改进棋盘。
棋盘改进
void display_board(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]);
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)//末行不用分割
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
{
printf("|");
}
}
printf("\n");
}
}
}看着挺复杂其实很简单，只要找出重复的部分再进行循环和判断就能打印出你想要的样子！
玩家下棋
void player_move(char board[ROW][COL], int row, int col)
{
int x;
int y;
while (1)
{
printf("请输入要下棋的坐标:>");
scanf("%d %d", &x, &y);
if (y <= col && x <= row)
{
if (board[x-1][y-1] == ' ')
{
board[x-1][y-1] = '*';
break;
}
else
{
printf("该坐标被占用，请重新输入\n");
}
}
else
{
printf("坐标非法，重新输入\n");
}
}
}测试：
电脑下棋
srand放在主函数里，循环体前，只需执行一次。
void computer_move(char board[ROW][COL], int row, int col)
{
while (1)
{
int x = rand() % 3;//0~2
int y = rand() % 3;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}
胜负评判
char is_win(char board[ROW][COL], int row, int col)
{
//行
int i = 0;
for (i = 0; i < row; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ')
{
return board[i][1];
}
}
//列
for (i = 0; i < col; i++)
{
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ')
{
return board[0][i];
}
}
//对角
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
if (is_full(board, row, col) == 1)
{
return 'Q';
}
//继续
return 'C';
}这里有个取巧的方法，可以直接用我们棋子所代表的字符作为返回值进行判断。
是否平局
static int is_full(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++)
{
if (' ' == board[i][j])
{
return 0;
}
}
}
return 1;
}这里的static是只对本文件可见，因为它只用于我们的胜负评判。
