说到三子棋,我想大家一定不陌生吧,它也是我童年中的一部分,今天我们用C语言来实现一下简易版的三子棋。
首先,介绍一下游戏规则:
1.在一个九宫格上进行下棋;
2.玩家两名,双方先后落子;
3.若在一条直线上有三颗同一玩家的棋子,则该玩家赢,若棋盘下满也没有出现三颗棋子在一条直线上,则为平局。
1.用do…while循环可以保证玩完一把还能接着玩,玩家可以自行选择继续玩还是退出。
2.用一个3x3的二维数组来存放玩家和电脑下的棋子,再进行判断输赢。
3.进行游戏的棋盘如下:
头文件game.h:
#include<stdio.h> #include<stdlib.h> #include<time.h> #define ROW 3 #define COL 3 //棋盘初始化 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 PlayerMove(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 char IsWin(char board[ROW][COL], int row, int col); //判断游戏输赢 //要返回4种不同的状态 //玩家赢 - '*' //电脑赢 - '#' //平局 - ‘Q' //继续 - 'C'
测试文件test.c:
#include"game.h" void menu() { printf("*****************************************\n"); printf("************ 1.play ***************\n"); printf("************ 0.exit ***************\n"); printf("*****************************************\n"); } void game() { char board[ROW][COL]; InitBoard(board, ROW, COL); //初始化棋盘 DisplayBoard(board, ROW, COL); //打印棋盘 char ret = 0; while (1) { PlayerMove(board, ROW, COL); DisplayBoard(board, ROW, COL); 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("平局\n"); } } int main() { int input = 0; srand((unsigned)time(NULL)); do { menu(); printf("请输入:"); 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函数里的函数,game.c文件:
#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 PlayerMove(char board[ROW][COL], int row, int col) { printf("玩家走:>\n"); int x = 0; int y = 0; while (1) { printf("请输入坐标:>"); scanf("%d%d", &x, &y);//2 1 表示第二行第一列 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; } } } int IsFull(char board[ROW][COL], int row, int col) { for (int i = 0; i < row; i++) { for (int j = 0; j < col; j++) { if (board[i][j] == ' ') { return 0;//不满 } } } return 1;//棋盘满 } char IsWin(char board[ROW][COL], int row, int col) { //行 for (int 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]; } } //列 for (int 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[1][1] != ' ') return board[1][1]; if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ') return board[1][1]; //判断平局 if (IsFull(board, row, col)) { return 'Q'; } //游戏继续 return 'C'; }
