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//#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#include #include #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);
