三子棋是我们小时候经常玩的游戏,今天就分享一下如何用c语言简单实现三子棋吧
编译软件VS2019
c语言实现三子棋运用到了二维数组的知识,在编写三子棋程序时用到了多文件编译(不是必须的,但是使用多文件编译会增加代码的可读性),首先我们先建立一个头文件和两个源文件·:
test.c//主程序 函数实现
game.c//主要用于自定义函数的定义
game.h//声明自定义函数
主要代码实现
test.c
调用各个功能的函数
#define _CRT_SECURE_NO_WARNINGS 1
#include<stdio.h> //#include<>:编译器直接从系统类库目录里查找头文件:
#include"game.h" //#include"":默认从项目当前目录查找头文件,所谓项目当前目录,就是项目工程文件所在的目录
void menu() {
printf("*********************************\n");
printf("************* 1.play **********\n");
printf("************* 0.exit **********\n");
printf("*********************************\n");
}
void game() {
//三子棋过程
char board[row][col];//棋盘数组
//初始化棋盘--board的元素都给成空格
InitBoard(board, row, col);
//打印棋盘
DisplayBoard(board, row, col);
//下棋
char ret = 0;
while (1) {
PlayMove(board,row,col);
DisplayBoard(board, row, col);
//判断输赢
ret=IsWin(board, row, col);
if (ret != 'C') {
break;
}
ComputerMove(board,row,col);
DisplayBoard(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("和局\n");
DisplayBoard(board, row, col);
}
int main() {
int input = 0;
srand((unsigned int)time(NULL));
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("选择错误\n");
break;
}
} while (input);
return 0;
}
game.c
主程序当中的自定义函数的定义
#define _CRT_SECURE_NO_WARNINGS
#include "game.h"
void InitBoard(char board[row][col], int ROW, int COL) {
for (int i = 0; i < ROW; i++) {
for (int j = 0; j < COL; j++) {
board[i][j] = ' ';
}
}
}
void DisplayBoard(char board[row][col], int ROW, int COL) {
for (int i = 0; i < ROW; i++) {
//打印数据
for (int j = 0; j < COL; j++) {
printf(" %c ", board[i][j]);
if (j < COL - 1)
printf("|");
}
printf("\n");
//打印分割行
if (i < ROW - 1) {
for (int j = 0; j < COL; j++) {
printf("---");
if (j < COL - 1)
printf("+");
}
}
printf("\n");
}
}
void PlayMove(char board[row][col], int ROW, int COL) {
printf("玩家下棋:>\n");
int x = 0;
int y = 0;
while (1) {
printf("请输入坐标:>");
scanf("%d%d", &x, &y);
if (x >= 1 && x <= ROW && y >= 1 && y <= COL) {
if (board[x - 1][y - 1]==' ') {
board[x - 1][y - 1] = '*';
break;
}
else {
printf("坐标被占用,请重新输入\n");
}
}
else
printf("坐标非法,超出范围\n");
}
}
void ComputerMove(char board[row][col], int ROW, int COL) {
int x = 0;
int y = 0;
printf("电脑走:>\n");
while (1) {
x = rand() % ROW;
y = rand() % COL;
if (board[x][y] == ' ') {
board[x][y] = '#';
break;
}
}
}
//判断棋盘是否已满
int full(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) {
//1.判断输赢
//三行
int i = 0;
for (i = 0; i < ROW; i++) {
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ') {
return board[i][0];
}
}
//三列
for (i = 0; i < COL; i++) {
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ') {
return board[0][i];
}
}
//对角线
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[0][0] != ' ') {
return board[0][0];
}
else if (board[2][0] == board[1][1] && board[1][1] == board[0][2] && board[2][0] != ' ')
return board[1][1];
//2.判断平局
else if (full(board, ROW, COL) == 1)
return 'Q';
//3.游戏继续
else
return 'C';
}
game.h
用于声明自定义函数
#pragma once
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define row 3
#define col 3
//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 PlayMove(char board[row][col], int ROW, int COL);
//电脑下棋
void ComputerMove(char board[row][col], int ROW, int COL);
//判断输赢
//要返回四种不同的状态
//玩家赢-返回“*”,电脑赢返回“#”,和局返回“Q”
//继续游戏返回'C'
char IsWin(char board[row][col], int ROW, int COL);
//判断棋盘是否已满
int full(char board[row][col], int ROW, int COL);
