小小三子棋

本文主要是介绍小小三子棋，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

写呀写呀写终于写了个三子棋

定义规则及判定的test.c

#include "test.h"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] = ' ';}}
}void ShowBoard(char board[][COL], int row, int col)//显示棋盘
{printf(" \\ | [ 1 ] | [ 2 ] | [ 3 ] |\n");int i = 0;for (; i < row; i++){printf("----------------------------\n");printf(" %d | [ %c ] | [ %c ] | [ %c ] |\n", i + 1, board[i][0], board[i][1], board[i][2]);}printf("----------------------------\n");
}int PlayerMove(char board[][COL], int row, int col)
{int x = 0;int y = 0;printf("Please Enter Your Pos<x, y># ");scanf("%d %d", &x, &y);if (x >= 1 && x <= 3 && y >= 1 && y <= 3){if (board[x - 1][y - 1] != ' '){return 2;}board[x - 1][y - 1] = BLACK_PIECE;return 0;}return 1; //用户输入坐标有误
}//用户赢了 BLACK_PIECE 'X'
//电脑赢了 WHITE_PIECE 'O'
//平局, 'E'
//next, 'N'
char JudgeResult(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[0][0];}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';
}void ComputerMove(char board[][COL], int row, int col)
{while (1){int i = rand() % row;int j = rand() % col;if (board[i][j] == ' '){board[i][j] = WHITE_PIECE;break;}}printf("Computer ... Done\n");Sleep(1000);
}
void Game()
{char board[ROW][COL];InitBoard(board, ROW, COL);char result = 'N';srand((unsigned long)time(NULL));while (1){ShowBoard(board, ROW, COL);int type = PlayerMove(board, ROW, COL);if (1 == type){printf("坐标有误，请重输\n");continue;}else if (2 == type){printf("你输入的坐标已经被占用，请重新输入！\n");continue;}else{printf("Player  ... Done!\n");}result = JudgeResult(board, ROW, COL);if (result != 'N'){break;}ComputerMove(board, ROW, COL);result = JudgeResult(board, ROW, COL);if (result != 'N'){break;}}ShowBoard(board, ROW, COL);switch (result){case 'E':printf("平局!\n");break;case BLACK_PIECE:printf("u win!\n");break;case WHITE_PIECE:printf("u lost!\n");break;default://bug!!break;}
}

简略来讲如下

• 初始化棋盘
• 显示棋盘
• 人走
• 判定（显示）
• 机走
• 判定（显示）
• 。。。
• 判定输赢（显示）

设立界面的main.c

#include "test.h"void Menu()//建立菜单
{printf("######################\n");printf("######  三子棋  ######\n");printf("### 1.Play   2.Exit ##\n");printf("######################\n");printf("please select: >> ");
}int main()
{int quit = 0;while (!quit){int select = 0;Menu();scanf("%d", &select);switch (select){case 1:Game();break;case 2:quit = 1;break;default:printf("Enter Error!\n");break;}}system("pause");return 0;
}

包含菜单等
