用C语言实现简单的三子棋
三子棋代码的实现需要一个简单的思路做指引,所以我们先来做一下思路的整理,代码的实现主要分为以下几个步骤:
1.初始化数组
2.显示数组
3.电脑走
4.玩家走
5.判断输赢
所以,先写出源文件game.h,如下。
#ifndef __GAME_H__ #define __GAME_H__ #define ROWS 3 //定义行 #define COLS 3 //定义列 //初始化数组 void init_board(char board[ROWS][COLS], int rows, int cols); //显示数组 void display_board(char board[ROWS][COLS], int rows, int cols); //电脑走 void computer_move(char board[ROWS][COLS], int rows, int cols); //玩家走 void player_move(char board[ROWS][COLS], int rows, int cols); //判断输赢 char check_win(char board[ROWS][COLS], int rows, int cols); #endif//__GAME_H__
接下来再写出主体的main函数,使这个三子棋的大体先做出来。以下为main.c函数。要实现的主要为选择界面以及大体的顺序。
#define _CRT_SECURE_NO_WARNINGS #include"game.h" #include<stdio.h> #include<stdlib.h> #include<time.h> void menu() { printf("*******************************\n"); printf("*****1.paly 2.exit *********\n"); printf("*******************************\n"); } void game() { char ret = 0; char board[ROWS][COLS] = { 0 }; init_board(board, ROWS, COLS); while (1) { printf("电脑走:\n"); computer_move(board, ROWS, COLS); display_board(board, ROWS, COLS); ret = check_win(board, ROWS, COLS); if (ret != 'q') { break; } printf("玩家走:\n"); player_move(board, ROWS, COLS); display_board(board, ROWS, COLS); ret = check_win(board, ROWS, COLS); if (ret != 'q') { break; } } if (ret == '*') { printf("玩家赢了!\n"); } else if (ret == 'o') { printf("电脑赢了!\n"); } else if (ret == ' ') { printf("平局!\n"); } } int main() { int input = 0; srand((unsigned)time(NULL)); do { menu(); printf("请选择:"); scanf("%d", &input); switch (input) { case 1: game(); break; case 2: return 0; break; default: printf("输入错误,请重新输入!\n"); break; } } while (input); system("pause"); return 0; }
以下为函数模块功能的的分布实现:
#define _CRT_SECURE_NO_WARNINGS #include"game.h" #include<stdio.h> #include<stdlib.h> #include<time.h> void init_board(char board[ROWS][COLS], int rows, int cols) { int i = 0; int j = 0; for (i = 0; i < rows; i++) { for (j = 0; j < cols; j++) { board[i][j] = ' '; } } } void display_board(char board[ROWS][COLS], int rows, int cols) //显示棋盘 { int i = 0; for (i = 0; i < rows; i++) { printf("| %c | %c | %c |\n", board[i][0], board[i][1], board[i][2]); if (i <= rows - 1) { printf("|----|----|----|\n"); } } } void computer_move(char board[ROWS][COLS], int rows, int cols) //电脑走 { while (1) { int x = rand() % 3; int y = rand() % 3; if (board[x][y] != '*' && board[x][y] != 'o') { board[x][y] = 'o'; return; } } } void player_move(char board[ROWS][COLS], int rows, int cols) //玩家走 { int x = 0; int y = 0; printf("玩家请输入位置,如:x y》"); do { scanf("%d %d", &x, &y); if (board[x - 1][y - 1] == 'o') { printf("该位置已经被占用,请重新输入:》"); } else if (((x - 1)>3) || ((y - 1)>3) || (x - 1 < 0) || (y - 1 < 0)) { printf("输入位置错误,请重新输入:》"); } else { board[x - 1][y - 1] = '*'; break; } } while (1); } static int is_full(char board[ROWS][COLS], int rows, int cols) //判断棋盘满没有 { int i = 0; int j = 0; for (i = 0; i < rows; i++) { for (j = 0; j <cols; j++) { if (board[i][j] == ' ') { return 0; } } } return 1; } char check_win(char board[ROWS][COLS], int rows, int cols) //判断输赢 { int k = 1; int i = 0; for (i = 0; i < rows; i++) //判断行 { if ((board[i][0] == board[i][1]) && (board[i][1] == board[i][2]) && board[i][0] != ' ') { return board[i][0]; } } for (i = 0; i < cols; i++) //判断列 { if ((board[0][i] == board[1][i]) && (board[1][i] == board[2][i]) && (board[0][i] != ' ')) { return board[0][i]; } } if ((board[0][0] == board[1][1]) && (board[1][1] == board[2][2]) && (board[0][0] != ' ')) //判断正斜 { return board[1][1]; } if ((board[0][2] == board[1][1]) && (board[1][1] == board[2][0]) && (board[0][2] != ' ')) //判断反斜 { return board[0][2]; } if (is_full(board, rows, cols)) { return ' '; } return 'q'; }
以下为程序运行的三种结果:
