1.整体思路
用C语言实现三子棋，首先你要明确实现思路，实现过程。
a.目录实现-->b.下棋数据的存储-->c.初始化棋盘-->d.打印棋盘-->e.玩家下棋-->f.电脑下棋-->g.判断输赢-->h.宏观调整逻辑实现
2.分模块实现
a.目录实现
#define _CRT_SECURE_NO_WARNINGS 1 #include<stdio.h> void menu() { printf("*******三子棋人机对战*******\n"); printf("****************************\n"); printf("******* 1.play *******\n"); printf("******* 0.exit *******\n"); printf("****************************\n"); } void test() { int input = 0; menu(); do { 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); } int main() { test(); return 0; }
b.游戏整体实现
#include "game.h" void game() { char ret = 0; //存储下棋的数据（3x3的二维数组） char board[ROW][COL] = { 0 }; //初始化棋盘 InitBoard(board, ROW, COL); //打印棋盘 DisplayBoard(board, ROW, COL); while (1) { //玩家下棋 player_move(board, ROW, COL); DisplayBoard(board, ROW, COL); //判断输赢 ret = is_win(board, ROW, COL); if (ret != 'C') { break; } //电脑下棋 computer_move(board, ROW, COL); DisplayBoard(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"); } }
c.宏定义 功能函数的声明
#pragma once #define ROW 3 #define COL 3 #include<stdio.h> #include<stdlib.h> #include<time.h> //初始化棋盘 void InitBoard(char board[ROW][COL], int row, int col); //打印棋盘 void DisplayBoard(char board[ROW][COL], int row, int col); //玩家下棋 void player_move(char board[ROW][COL], int row, int col); //电脑下棋 void computer_move(char board[ROW][COL], int row, int col); //判断输赢 char is_win(char board[ROW][COL], int row, int col);
d.功能函数
#define _CRT_SECURE_NO_WARNINGS 1 #include"game.h" void InitBoard(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++) { board[i][j] = ' '; } } } void DisplayBoard(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++) { printf(" %c ", board[i][j]); if (j < col - 1) { printf("|"); } } printf("\n"); for (j = 0; j < col; j++) { if (i < row - 1) { printf("---"); if (j < col - 1) { printf("|"); } } } printf("\n"); } } void player_move(char board[ROW][COL], int row, int col) { int x = 0; int y = 0; printf("玩家下棋\n"); while (1) { printf("请输入坐标;>"); scanf("%d %d", &x, &y); if (x >= 1 && x <= row && y >= 1 && y <= col && board[x-1][y-1] == ' ') { board[x - 1][y - 1] = '*'; break; } else { printf("输入错误，请重新输入\n"); } } } void computer_move(char board[ROW][COL], int row, int col) { while (1) { int x = rand() % row; int y = rand() % col; if (board[x][y] == ' ') { board[x][y] = '#'; break; } } } 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; } char is_win(char board[ROW][COL], int row, int col) { int i = 0; //判断行 for (i = 0; i < row; i++) { if (board[i][0] == board[i][1] && board[i][0] == board[i][2] && board[i][1] != ' ') { return board[i][0]; } } //判断列 for (i = 0; i < col; i++) { if (board[0][i] == board[1][i] && board[0][i] == board[2][i] && board[1][i] != ' ') { return board[0][i]; } } //对角线 if (board[1][1] == board[2][2] && board[0][0] == board[2][2] && board[0][0] != ' ') { return board[0][0]; } if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ') { return board[1][1]; } if (is_full(board, ROW, COL) == 1) { return 'Q'; } return 'C'; }
效果呈现
