前言 ：用c语言实现三子棋可分为六个步骤！
1：首先是小游戏开始的准备工作-----
首先我们要进入小游戏至少要选择一次，我们用一个do--while语句来实现！
然后建立一个简易菜单-----
void menu() { printf("***************************\n"); printf("****** 1.play ******\n"); printf("****** 0.exit ****\n"); printf("***************************\n"); }
之后再用一个选择语句供玩家选择-----
do { menu(); printf("请输入选项->\n"); 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);
此时已经成型，进入下一个步骤即可！
2：创建棋盘（一个二维数组),对其初始化----
//初始化棋盘 init(board, ROW, COL);
对棋盘上的棋子都赋予空格
void init(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] = ' '; } } }
进行下一个步骤！
3：打印棋盘----
//打印棋盘 display(board, ROW, COL);
顾名思义，要打印一个3*3的“井”类图样，并且对其棋子赋值----
表格示例----
| | ---|---|--- | | ---|---|--- | |
代码实现如图：
void display(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"); if (i < row - 1) { for (j = 0; j < col; j++) { printf("---"); if (j < col-1) printf("|"); } printf("\n"); } } }
进入下一个步骤！
4：玩家开始下棋，且打印棋盘---
//玩家下棋 playermove(board, ROW, COL); display(board, ROW, COL);
代码实现如图-----
void playermove(char board[ROW][COL], int row, int col) { int x = 0; int y = 0; while (1) { printf("玩家下棋->\n"); scanf("%d%d", &x, &y); if (x <= row && y <= col) { if (board[x - 1][y - 1] == ' ') { board[x - 1][y - 1] = '*'; break; } else printf("位子被占，请重新输入->\n"); } else printf("输入非法，请重新输入->\n"); } }
进入下一个步骤！
5：轮到电脑开始下棋，且打印棋盘---
//电脑下棋 compmove(board, ROW, COL); display(board, ROW, COL);
代码实现如图----
void compmove(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; y = rand() % col; if (board[x][y] == ' ') { board[x][y] = '#'; break; } } }
因为电脑是无规则下棋，所以其中采用了---“时间戳”！
rand()----会生成随机数。
rand函数的使用使用需要引----"srand"!
srand((unsigned int)time(NULL));
使用“rand”函数只需引用一次"srand"----所以将其放首位即可！
int main() { srand((unsigned int)time(NULL));
同时需要引头文件----
#include<stdlib.h> #include<time.h>
完成即进入下一步！
6：玩家或电脑每次下完棋都要判断输赢---
//判断输赢 ret=iswin(board, ROW, COL);
共有4种结果---平局---玩家赢---电脑赢---继续---
使用不同的返回值来进行判断---
while (1) { //玩家下棋 playermove(board, ROW, COL); display(board, ROW, COL); //判断输赢 ret=iswin(board, ROW, COL); if (ret != 'c') break; //电脑下棋 compmove(board, ROW, COL); display(board, ROW, COL); ret = iswin(board, ROW, COL); if (ret != 'c') break; } if (ret == '*') printf("玩家赢\n"); else if (ret == "#") printf("电脑赢\n"); else printf("平局\n");
函数代码实现如图所示--
int flat(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++) { if (board[i][j] == ' ') return 0; } } return 1; } char iswin(char board[ROW][COL], int row, int col) { int i = 0; //行 for (i = 0; i < row; i++) { if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ') return board[i][1]; } //列 int j = 0; for (j = 0; j < col; j++) { if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[1][j] != ' ') return board[1][j]; } //对角 if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ') return board[1][1]; else if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ') return board[1][1]; else if (flat(board, ROW, COL) == 1) return 'q'; else return 'c'; }
然后就ok了！
主要还是细心，一步一步来，切记不可出错！
可以在写作的过程中多运用几个文件分工会更加明确！
此代码我分为了三个文件！
以下是总代码的实现---
-----test.c---文件名--起始文件-
#define _CRT_SECURE_NO_WARNINGS 1 #include"game.h" void menu() { printf("***************************\n"); printf("****** 1.play ******\n"); printf("****** 0.exit ****\n"); printf("***************************\n"); } void game() { char board[ROW][COL] = { 0 }; //初始化棋盘 init(board, ROW, COL); //打印棋盘 display(board, ROW, COL); int ret = 0; while (1) { //玩家下棋 playermove(board, ROW, COL); display(board, ROW, COL); //判断输赢 ret=iswin(board, ROW, COL); if (ret != 'c') break; //电脑下棋 compmove(board, ROW, COL); display(board, ROW, COL); ret = iswin(board, ROW, COL); if (ret != 'c') break; } if (ret == '*') printf("玩家赢\n"); else if (ret == "#") printf("电脑赢\n"); else printf("平局\n"); } int main() { srand((unsigned int)time(NULL)); int input = 0; do { menu(); printf("请输入选项->\n"); 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; }
----game.h----头文件名--负责函数的声明
#pragma once #include<stdio.h> #include<stdlib.h> #include<time.h> #define ROW 3 #define COL 3 void init(char board[ROW][COL],int row,int col); void display(char board[ROW][COL], int row, int col); void playermove(char board[ROW][COL], int row, int col); void compmove(char board[ROW][COL], int row, int col); char iswin(char board[ROW][COL], int row, int col);
-----game.c----文件名---负责函数的实现
#define _CRT_SECURE_NO_WARNINGS 1 #include"game.h" void init(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 display(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"); if (i < row - 1) { for (j = 0; j < col; j++) { printf("---"); if (j < col-1) printf("|"); } printf("\n"); } } } void playermove(char board[ROW][COL], int row, int col) { int x = 0; int y = 0; while (1) { printf("玩家下棋->\n"); scanf("%d%d", &x, &y); if (x <= row && y <= col) { if (board[x - 1][y - 1] == ' ') { board[x - 1][y - 1] = '*'; break; } else printf("位子被占，请重新输入->\n"); } else printf("输入非法，请重新输入->\n"); } } void compmove(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; y = rand() % col; if (board[x][y] == ' ') { board[x][y] = '#'; break; } } } int flat(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++) { if (board[i][j] == ' ') return 0; } } return 1; } char iswin(char board[ROW][COL], int row, int col) { int i = 0; //行 for (i = 0; i < row; i++) { if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ') return board[i][1]; } //列 int j = 0; for (j = 0; j < col; j++) { if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[1][j] != ' ') return board[1][j]; } //对角 if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ') return board[1][1]; else if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ') return board[1][1]; else if (flat(board, ROW, COL) == 1) return 'q'; else return 'c'; }
以上就是用c语言对三子棋的实现---如果对你有启发的话------就给哥们来个一键三连！
拜拜了您嘞！
