这篇文章主要为大家展示了“C语言如何开发实现井字棋”,内容简而易懂,条理清晰,希望能够帮助大家解决疑惑,下面让小编带领大家一起研究并学习一下“C语言如何开发实现井字棋”这篇文章吧。
井字棋棋盘我们总体可以当成一个二维数组来操作,我们分别需要实现初始化二维数组,打印棋盘,玩家下棋,电脑下棋,判断输赢等代码
我们创建了头文件用于放函数的声明,game.c文件放置函数的实现,test.c文件用于测试。
电脑获胜:
玩家获胜:
平局:
我们在game.c文件中实现函数功能的代码
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++) { for (int j = 0; j < col; j++) { printf(" %c ", Board[i][j]); if (j < col - 1) printf("|"); } printf("\n"); if (i < row - 1) { for (int j = 0; j < col; j++) { printf("---"); if (j < col - 1) printf("|"); } } printf("\n"); } }
这里的棋盘我们只打印了井字的形状,如果为了美观,还可以进行封边,这里就留给朋友们自行实现啦。
void PlayMove(char Board[ROW][COL], int row, int col) { while (1) { int x = 0, y = 0; printf("请输入坐标:\n"); 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("该位置已被占,请重新输入:\n"); } else { printf("输入错误,请重新输入:\n"); } } }
在电脑落子之前,先检测有没有下一步可以直接赢的,若有,则落子在此处,电脑获胜,若没有,再检测玩家下一步是否有机会获胜,若玩家下一步可以直接获胜,那么电脑将抢占这一步。
如果上述两种情况均不存在,当发现(1,1)位置是空时,电脑先下这一步。
其他情况均随意落子。
void ComputerMove(char Board[ROW][COL], int row, int col) { int x = 0, y = 0; while (1) { if (JudgeComputer(Board, ROW, COL)) { for (int i = 0; i < row; i++) { if (Board[i][0] == Board[i][1] && Board[i][0] == '*' && Board[i][2] == ' ') { Board[i][2] = '*'; return; } else if (Board[i][0] == Board[i][2] && Board[i][0] == '*' && Board[i][1] == ' ') { Board[i][1] = '*'; return; } else if (Board[i][1] == Board[i][2] && Board[i][1] == '*' && Board[i][0] == ' ') { Board[i][0] = '*'; return; } } for (int j = 0; j < col; j++) { if (Board[0][j] == Board[1][j] && Board[0][j] == '*' && Board[2][j] == ' ') { Board[2][j] = '*'; return; } else if (Board[0][j] == Board[2][j] && Board[0][j] == '*' && Board[1][j] == ' ') { Board[1][j] = '*'; return; } else if (Board[1][j] == Board[2][j] && Board[1][j] == '*' && Board[0][j] == ' ') { Board[0][j] = '*'; return; } } if (Board[0][0] == Board[1][1] && Board[0][0] == '*' && Board[2][2] == ' ') { Board[2][2] = '*'; return; } else if (Board[0][0] == Board[2][2] && Board[0][0] == '*' && Board[1][1] == ' ') { Board[1][1] = '*'; return; } else if (Board[1][1] == Board[2][2] && Board[1][1] == '*' && Board[0][0] == ' ') { Board[0][0] = '*'; return; } else if (Board[0][2] == Board[1][1] && Board[0][2] == '*' && Board[2][0] == ' ') { Board[2][0] = '*'; return; } else if (Board[0][2] == Board[2][0] && Board[0][2] == '*' && Board[1][1] == ' ') { Board[1][1] = '*'; return; } else if (Board[2][0] == Board[1][1] && Board[2][0] == '*' && Board[0][2] == ' ') { Board[0][2] = '*'; return; } } else if (JudgePlayer(Board, ROW, COL)) { for (int i = 0; i < row; i++) { if (Board[i][0] == Board[i][1] && Board[i][0] == '#' && Board[i][2] == ' ') { Board[i][2] = '*'; return; } else if (Board[i][0] == Board[i][2] && Board[i][0] == '#' && Board[i][1] == ' ') { Board[i][1] = '*'; return; } else if (Board[i][1] == Board[i][2] && Board[i][1] == '#' && Board[i][0] == ' ') { Board[i][0] = '*'; return; } } for (int j = 0; j < col; j++) { if (Board[0][j] == Board[1][j] && Board[0][j] == '#' && Board[2][j] == ' ') { Board[2][j] = '*'; return; } else if (Board[0][j] == Board[2][j] && Board[0][j] == '#' && Board[1][j] == ' ') { Board[1][j] = '*'; return; } else if (Board[1][j] == Board[2][j] && Board[1][j] == '#' && Board[0][j] == ' ') { Board[0][j] = '*'; return; } } if (Board[0][0] == Board[1][1] && Board[0][0] == '#' && Board[2][2] == ' ') { Board[2][2] = '*'; return; } else if (Board[0][0] == Board[2][2] && Board[0][0] == '#' && Board[1][1] == ' ') { Board[1][1] = '*'; return; } else if (Board[1][1] == Board[2][2] && Board[1][1] == '#' && Board[0][0] == ' ') { Board[0][0] = '*'; return; } else if (Board[0][2] == Board[1][1] && Board[0][2] == '#' && Board[2][0] == ' ') { Board[2][0] = '*'; return; } else if (Board[0][2] == Board[2][0] && Board[0][2] == '#' && Board[1][1] == ' ') { Board[1][1] = '*'; return; } else if (Board[2][0] == Board[1][1] && Board[2][0] == '#' && Board[0][2] == ' ') { Board[0][2] = '*'; return; } } else { if (Board[1][1] == ' ') { Board[1][1] = '*'; return; } else { x = rand() % row; y = rand() % col; if (Board[x][y] == ' ') { Board[x][y] = '*'; break; } } } } }

我们在game.h头文件中进行函数的声明。
void meun(); #define ROW 3 #define COL 3 //游戏主函数 void game(); //初始化二维数组 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); //判断赢否 char IsWin(char Board[ROW][COL], int row, int col); //判断棋盘满了吗 //int IsFull(char Board[ROW][COL], int row, int col); //判断电脑下一部是否可以直接赢 //int JudgeComputer(char Board[ROW][COL], int row, int col); //判断玩家下一步是否会赢 //int JudgePlayer(char Board[ROW][COL], int row, int col);
我们在test.c文件中测试该游戏。
#include "game.h" void game() { char ret = 0; char Board[ROW][COL] = { 0 }; //初始化数组 InitBoard(Board, ROW, COL); //打印棋盘 printf("棋盘如下:\n"); DisplayBoard(Board, ROW, COL); while (1) { //玩家下棋 printf("玩家落子:\n"); PlayMove(Board, ROW, COL); //每下一步打印一次棋盘 DisplayBoard(Board, ROW, COL); //每下一步判断一次胜负 ret = IsWin(Board, ROW, COL); if (ret != 'C') { break; } //电脑下棋 printf("电脑落子:\n"); ComputerMove(Board, ROW, COL); //每下一步打印一次棋盘 DisplayBoard(Board, ROW, COL); ret = IsWin(Board, ROW, COL); if (ret != 'C') { break; } } if (ret == '#') printf("玩家获胜\n"); else if (ret == '*') printf("电脑获胜\n"); else if (ret == 'o') printf("卧龙凤雏\n"); } void test() { int input = 0; srand((size_t)time(NULL)); do { meun(); printf("请选择:>"); scanf("%d", &input); switch (input) { case 1: game(); break; case 0: printf("游戏结束\n"); break; default: printf("输入错误,请重新输入:\n"); break; } } while (input); } int main() { test(); return 0; }
