前言
此次我们来进行三子棋的C语言编写。三子棋是在一个在3*3的方格中,将自己的三个棋子连成一条线,即可获胜。
一、所需函数
1.初始化棋盘函数(InitBoard)
2.打印棋盘函数(ShowBoard)
3.判断棋子是否连线成功函数(IsEnd)
4.玩家落子函数(PlayerMove)
5.电脑落子函数(ComputerMove)
6.菜单函数(Menu)
7.主函数
二、函数实现
1.基本流程
1).进入菜单界面
2).创建棋盘并初始化
3).打印棋盘
4).玩家落子
5).判定胜负关系
6).电脑落子
7).判定胜负关系
8).回到步骤3继续执行,直到不能继续落子
2.代码展示
采用多文件的形式展示
game.h代码如下:
#pragma once
#include<stdio.h>
#include <time.h>
#include <stdlib.h>
#include <windows.h>
#define ROW 3
#define COL 3
#define INIT ' '
#define WHITE 'X' //玩家赢
#define BLACK 'O' //电脑赢
#define DRAW 'D' //平局
#define NEXT 'N' //继续
#pragma warning(disable:4996)
extern void Game();
game.c代码如下:
#include "game.h"
static void InitBoard(char board[][COL], int row, int col) //初始化棋盘
{
for (int i = 0; i < row; i++){
for (int j = 0; j < col; j++){
board[i][j] = INIT;
}
}
}
static void ShowBoard(char board[][COL], int row, int col) //打印棋盘
{
system("cls");
printf(" ");
for (int i = 0; i < col; i++){
printf("%4d", i + 1);
}
printf("\\n--------------\\n");
for (int i = 0; i < row; i++){
printf("%-2d", i + 1);
for (int j = 0; j < col; j++){
printf("| %c ", board[i][j]);
}
printf("\\n--------------\\n");
}
}
//判断棋盘当前的局面,共四种可能
//#define WHITE 'X' //玩家
//#define BLACK 'O' //电脑
//#define DRAW 'D' //平局
//#define NEXT 'N' //继续
static char IsEnd(char board[][COL], int row, int col){
for (int i = 0; i < row; i++){ //判断行是否一样
if (board[i][0] == board[i][1] && \\
board[i][1] == board[i][2] && \\
board[i][2] != INIT){
return board[i][0];
}
}
for (int j = 0; j < col; j++){ //判断列是否一样
if (board[0][j] == board[1][j] && \\
board[1][j] == board[2][j] && \\
board[0][j] != INIT){
return board[0][j];
}
}
if (board[0][0] == board[1][1] && \\ //判断主对角线是否一样
board[1][1] == board[2][2] && \\
board[1][1] != INIT){
return board[1][1];
}
if (board[0][2] == board[1][1] && \\ //判断副对角线是否一样
board[1][1] == board[2][0] && \\
board[1][1] != INIT){
return board[1][1];
}
for (int i = 0; i < row; i++){ //判断没有一样的,继续
for (int j = 0; j < col; j++){
if (board[i][j] == INIT){
return NEXT;
}
}
}
return DRAW; //平局
}
static void PlayerMove(char board[][COL], int row, int col) //玩家移动
{
int x = 0;
int y = 0;
while (1){
printf("Please Enter Postion<x,y>:");
scanf("%d %d", &x, &y);
if (x < 1 || y < 1 || x > 3 || y > 3){
printf("Enter Postion Error!\\n");
continue;
}
if (board[x - 1][y - 1] == INIT){
board[x - 1][y - 1] = WHITE;
break;
}
else{
printf("Postion Is Not Empty!\\n");
}
}
}
static void ComputerMove(char board[][COL], int row, int col) //电脑移动
{
while (1){
int x = rand() % row;
int y = rand() % col;
if (board[x][y] == INIT){
board[x][y] = BLACK;
break;
}
}
}
void Game(){
char board[ROW][COL];
InitBoard(board, ROW, COL);
srand((unsigned long)time(NULL));
char result = 0;
while (1){
ShowBoard(board, ROW, COL);
PlayerMove(board, ROW, COL);
result = IsEnd(board, ROW, COL);
if (result != NEXT){
break;
}
ShowBoard(board, ROW, COL);
ComputerMove(board, ROW, COL);
result = IsEnd(board, ROW, COL);
if (result != NEXT){
break;
}
}
ShowBoard(board, ROW, COL);
switch (result){
case WHITE:
printf("You Win!\\n");
break;
case BLACK:
printf("You Lose!\\n");
break;
case DRAW:
printf("You == Computer!\\n");
break;
default:
printf("BUG!\\n");
break;
}
}
main.c代码如下:
#include"game.h"
void Menu(){
printf("+-------------------------+\\n");
printf("|1.Play 0.Exit|\\n");
printf("+-------------------------+\\n");
}
int main(){
int select = 0;
int quit = 0;
while (!quit){
Menu();
printf("Please select 1 or 0 :");
scanf("%d", &select);
switch (select){
case 1:
Game();
break;
case 0:
quit = 1;
break;
default:
printf("Enter Error,Please Try Again.\\n");
break;
}
}
printf("You are welcomed to come back next time to play!\\n");
system("pause");
return 0;
}
