C语言版实现三子棋游戏
如何用C语言来实现三子棋（井字棋），供大家参考，具体内容如下
大致思路如下
1.先打印出菜单供用户进行游戏还是退出游戏
2.编写打印棋盘的函数
3.编写用户和电脑下棋的函数
4.最后对玩家或用户下棋后进行判断输赢

实现打印菜单的函数
void menu()
{
printf("******************************************\n");
printf("************* 1. play *************\n");
printf("************* 2.exit *************\n");
printf("******************************************\n");
}
主函数的实现
int main()
{
int input;
srand((unsigned int)time(NULL));
do
{
menu();
printf("请选择>");
scanf("%d", &input);
switch (input)
{
case 0:
printf("退出\n");
break;
case 1:
game();
break;
default:
printf("输入错误，");
break;
}
} while (input);
return 0;
}
根据用户的选择是玩游戏还是退出，玩完一局后也可以在玩一局
game函数的实现
void game()
{
char board[ROW][COL];
//初始化棋盘
InitBoard(board, ROW, COL);
//打印棋盘
PrinBoard(board, ROW, COL);
char flag = 0;
//下棋
while (1)
{
PlayMove(board, ROW, COL);
PrinBoard(board, ROW, COL);
//判断当前状态
flag = IsWin(board, ROW, COL);
if (flag != 'c')
break;
//电脑下棋
CompMove(board, ROW, COL);
PrinBoard(board, ROW, COL);
//判断当前状态
flag = IsWin(board, ROW, COL);
if (flag != 'c')
break;
}
if (flag == '*')
printf("恭喜玩家获胜\n");
else if (flag == '#')
printf("恭喜电脑获胜\n");
else
printf("平局啦\n");
}
在每次玩家或电脑下完棋后都应该进行判断，判断当前棋盘的状态.
打印棋盘
首先应先打印棋盘，而且在每次下完棋后也应在打印一下棋盘
void PrinBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
int j = 0;
for (int j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
printf("|");
}
printf("\n");
if (i < row - 1)
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
}
printf("\n");
}
}
判断函数
IsWin函数应该有四种状态分别为：玩家赢（*）、电脑赢（#）、平局（d)和继续©。
char IsWin(char board[ROW][COL], int row, int col)
{
int i = 0;
//判断行
for (i = 0; i < row; i++)
{
int j = 0;
for (j = 0; j < col - 1; j++)
{
if (board[i][j] == ' ' || board[i][j] != board[i][j + 1])
break;
}
if (j == col - 1)
return board[i][j - 1];
}
//判断列
for (i = 0; i < col; i++)
{
int j = 0;
for (j = 0; j < row - 1; j++)
{
if (board[j][i] == ' ' || board[j][i] != board[j + 1][i])
break;
}
if (j == row - 1)
return board[j][i];
}
//右斜
for (i = 0; i < row - 1; i++)
{
if (board[i][i] == ' ' || board[i][i] != board[i + 1][i + 1])
break;
}
if (i == row - 1)
return board[i][i];
int x = 1, y = col - 2;
while (x < row&&y >= 0)
{
if (board[x][y] == ' ' || board[x][y] != board[x - 1][y + 1])
break;
x++;
y--;
}
if (x == row && y < 0)
return board[x - 1][y + 1];
//判断是否平局
for (i = 0; i < row; i++)
{
int j = 0;
for (j = 0; j < col; j++)
{
if (board[i][j] == ' ')
return 'c';
}
}
//平局
return 'd';
}
下棋函数
电脑下棋时通过时间戳来生成随机数，并判断当前位置是否合法。每次下完棋后应该对棋盘进行判断，通过调用函数IsWin根据返回值，判断是继续还是跳出。
void PlayMove(char board[ROW][COL], int row, int col)
{
printf("请玩家下棋>");
while (1)
{
int x, y;
printf("输入您要下的位置");
scanf("%d %d", &x, &y);
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
//判断当前位置是否有棋子
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = '*';
break;
}
else
printf("此位置重复\n");
}
else
printf("此坐标不合法，超出棋盘大小\n");
}
}
void CompMove(char board[ROW][COL], int row, int col)
{
printf("电脑下棋>\n");
printf("\n");
while (1)
{
int x = rand() % row;
int y = rand() % col;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}
到这各个函数的实现已完成。
完整代码如下
text.c
#include"game.h"
void menu()
{
printf("******************************************\n");
printf("************* 1. play *************\n");
printf("************* 2.exit *************\n");
printf("******************************************\n");
}
void game()
{
char board[ROW][COL];
//初始化棋盘
InitBoard(board, ROW, COL);
//打印棋盘
PrinBoard(board, ROW, COL);
char flag = 0;
//下棋
while (1)
{
PlayMove(board, ROW, COL);
PrinBoard(board, ROW, COL);
//判断当前状态
flag = IsWin(board, ROW, COL);
if (flag != 'c')
break;
//电脑下棋
CompMove(board, ROW, COL);
PrinBoard(board, ROW, COL);
//判断当前状态
flag = IsWin(board, ROW, COL);
if (flag != 'c')
break;
}
