前言

今天带来的内容是五子棋项目的具体实现，其实咱们上回已经实现了三子棋，
链接如下：
【C语言】三子棋详解(包教包会的那种)
但是呢，上回咱们的三子棋其实还有非常多需要优化的地方，我们今天就来优化一下并把它改为五子棋。

一.上回三子棋的源码

• 上回讲过的东西就不再缀叙了，详情请看上方链接，这里就只把上回的源码贴出来方便大家更好的理解之后的内容。
• 以下为三子棋具体的每个文件中的源码哦,需要自取

1.game.h(头文件)

#include#include#include#define Col 3#define Row 3void InitBoard(char board[Row][Col], int row, int col);//初始化棋盘void PrintBoard(char board[Row][Col], int row, int col);//打印棋盘void PlayBoard(char board[Row][Col], int row, int col);//玩游戏void ComputerBoard(char board[Row][Col], int row, int col);//电脑下int IsFull(char board[Row][Col], int row, int col);//棋盘是否已满int Is_Win(char board[Row][Col], int row, int col);//判断谁赢

2.game.c（定义函数的文件）

#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 PrintBoard(char board[Row][Col], int row, int col){int i = 0;//打印数据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 PlayBoard(char board[Row][Col], int row, int col){int x, y = 0;while (1){printf("玩家下棋>:\n");printf("请输入要下的坐标，中间用空格隔开\n");scanf("%d %d", &x, &y);//判断输入坐标的合法性if (x >= 1 && x <= row && y >= 1 && y <= col){if (board[x - 1][y - 1] == ' '){board[x - 1][y - 1] = '*';break;}elseprintf("坐标已被占用，请重新输入\n");}elseprintf("坐标非法，请重新输入\n");}}void ComputerBoard(char board[Row][Col], int row, int col){int x = 0;int y = 0;printf("电脑下棋:>\n");while(1){x = rand() % row;//生成0-row-1的数y = rand() % col;//生成0-col-1的数if (board[x][y] == ' '){board[x][y] = '#';break;}}}int IsFull(char board[Row][Col], int row, int col){int i ,j;for (i = 0; i < row; i++){for (j = 0; j < col; j++){if (board[i][j] == ' ')return 0;}}return 1;}int Is_Win(char board[Row][Col], int row, int col){int x = 0;int y = 0;//竖着if (board[x][0] == board[x][1] && board[x][1] == board[x][2] && board[x][0] !=' '){return board[x][0];}//横着if (board[0][y] == board[1][y] && board[1][y] == board[2][y] && board[0][y] != ' '){return board[0][y];}//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];if (IsFull(board, row, col) == 1){return 'Q';}return 'C';}

3.test.c（主文件）

#include"game.h"void menu()//打印菜单{printf("*****************************\n");printf("*********** 1.play **********\n");printf("*********** 0.exit **********\n");printf("*****************************\n");}void game(){char board[Row][Col] = { 0 };InitBoard(board, Row, Col);PrintBoard(board,Row, Col);char ret = 0;while (1){PlayBoard(board, Row, Col);PrintBoard(board, Row, Col);ret = Is_Win(board, Row, Col);if (ret != 'C')break; ComputerBoard(board, Row, Col);PrintBoard(board, Row, Col);ret = Is_Win(board, Row, Col);if (ret != 'C')break;}if (ret == '*')printf("玩家赢\n");if (ret == '#')printf("电脑赢\n");if (ret == 'Q')printf("平局\n");}int main(){srand((unsigned int)time(NULL));int input = 0;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("输入错误，请重新输入\n");break;}}while(input);return 0;}

• 看看游戏效果

二.五子棋

1.棋盘大小

• 三子棋的棋盘大小是3*3的，对于五子棋来说显然不够，这下咱们之前定义的Row与Col就发挥了作用，当我们想改变棋盘大小时，只需要改变它俩的值即可！

#define Col 10#define Row 10

• 效果如图，如果你还想改的更大一点，当然也可以
• 15*15的棋盘
  
• 这一步完成

2.判断胜负条件

• 我们现在既然是五子棋，那么判断胜负的条件自然也要变化一下啦，我们先回顾一下三子棋中判断胜负的函数

int IsFull(char board[Row][Col], int row, int col){int i ,j;for (i = 0; i < row; i++){for (j = 0; j < col; j++){if (board[i][j] == ' ')return 0;}}return 1;}int Is_Win(char board[Row][Col], int row, int col){int x = 0;int y = 0;//竖着if (board[x][0] == board[x][1] && board[x][1] == board[x][2] && board[x][0] !=' '){return board[x][0];}//横着if (board[0][y] == board[1][y] && board[1][y] == board[2][y] && board[0][y] != ' '){return board[0][y];}//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];if (IsFull(board, row, col) == 1){return 'Q';}return 'C';}

• 首先我们的判定要从三子改为五子
• 其次，我们发现，上面的代码不具有灵活性，注意这里：

//竖着if (board[x][0] == board[x][1] && board[x][1] == board[x][2] && board[x][0] !=' '){return board[x][0];}//横着if (board[0][y] == board[1][y] && board[1][y] == board[2][y] && board[0][y] != ' '){return board[0][y];}//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];

• 这中间我们发现它的判定方式是直接与棋盘挂钩的，只能在3*3的棋盘中使用，最明显的地方是对角线，上面代码的判定方式是直接判定(1,1)(2,2)(3,3)或者（1,3）(2,2)(3,1)中存放的元素是否相等，一旦我们把棋盘的大小改变，就无法正确判定输赢了。比如这样：
  
• 此时我们已经获胜了，但是程序却没有判定我们胜利
• 改进代码如下：

int Is_Win(char board[Row][Col], int row, int col){int i = 0;int j = 0;//竖着if (j < col - 4)//防止越界if (board[i][j] == board[i][j + 1] && board[i][j] ==board[i][j + 2]&& board[i][j] == board[i][j + 3] && board[i][j]== board[i][j + 4])return board[i][j];//横着if (i < row - 4)if(board[i][j] == board[i][j + 1] && board[i][j] ==board[i][j + 2]&& board[i][j] == board[i][j + 3] && board[i][j]== board[i][j + 4]) return board[i][j];//左对角线连成五子if (i < row - 4 && j < col - 4)if (board[i][j] ==board[i + 1][j + 1] && board[i][j] ==board[i + 2][j + 2]&& board[i][j] == board[i + 3][j + 3] && board[i][j] == board[i + 4][j + 4])return board[i][j];// 右对角线连成五子 if (i < row - 4 && j > 4)if (board[i][j] == board[i + 1][j - 1] &&board[i][j] ==board[i + 2][j - 2]&& board[i][j] == board[i + 3][j - 3] && board[i][j] == board[i + 4][j - 4])return board[i][j];if (IsFull(board, row, col) == 1){return 'Q';}return 'C';}

• 把三子变成了五子，同时增加了代码的灵活性，方便我们以后玩六子棋等什么的。

3.试玩一下

• 游戏效果如图
  
• 虽然格子简陋一点，但是我们需要的功能完美实现！

4.五子棋的源码

• 下面把源码给大家分享一下，方便大家试玩以及修改自己在编写时可能出现的错误

总结

• 结合咱们上回三子棋实现的详解，其实五子棋也没啥难的，如果你上次的三子棋没有自己独立的编写过，真的墙裂建议你试试五子棋的，毕竟代码只有自己亲手编写过了才能真正做到对它的理解。
