三子棋分析与实现——C语言
首先介绍一下三子棋规则：只要将自己的棋连成一条线（行，列，斜线），即为赢
如图：
1.我们可以将棋盘看做是一个三行三列的二维数组，且每行每列用线隔开以便区分
2.分为电脑下棋和玩家下棋（电脑先下和玩家先下）
3.判断输赢（玩家赢，电脑赢和平局）
创建tset.c，game.c和head.h三个文件
1.在test.c中编写主函数并写出游戏菜单在这里我分为电脑先下和玩家先下，代码如下；
void menu(){ printf("***************************************\n"); printf("* 1.play 0.exit *\n"); printf("***************************************\n");}void first_move(){ printf("***************************************\n"); printf("* 1.computer first 2.player first *\n"); printf("***************************************\n");}void game(){ return 0；}int main(){ int choice; srand((unsigned int)time(NULL));//产生随机数 do { menu(); printf("请选择:"); scanf("%d", &choice); switch (choice) { case 1: game(); break; case 0: break; default: printf("输入错误请重新输入.\n"); break; } } while (choice); return 0;}2.下来逐步在game.c中实现所需功能并且在game函数中调用
先打印出棋盘，并将棋盘初始化为空格。代码如下；
void show_board(char board[ROWS][COLS], int rows, int cols)//打印棋盘{ int i; for (int i = 0; i < rows; i++) { printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]); if (i != rows - 1) printf(" ---|---|--- \n"); }}void init_board(char board[ROWS][COLS], int rows, int cols)//将数组初始化为空格{ int i, j; for (i = 0; i < rows; i++) { for (j = 0; j < cols; j++) { board[i][j] = ' '; } }}
效果如图
玩家数输入二维数组的坐标，这时需要判断玩家输入坐标是否合理以及在此坐标上是否有棋子，代码如下；
void player_move(char board[ROWS][COLS], int rows, int cols)//玩家落子{ int x, y; printf("玩家落子:\n"); while (1) { scanf("%d %d", &x, &y); if (x >= 1 && x <= rows && y >= 1 && y <= cols) { if (board[x - 1][y - 1] == ' ') { board[x - 1][y - 1] = '*'; break; } else printf("位置已被占用！请再试一次。\n"); } else printf("输入错误!请重新输入.\n"); }}4.玩成电脑落子
这里实现的是电脑在为空格的数组中随机落子。代码如下；
void computer_move(char board[ROWS][COLS], int rows, int cols)// 电脑落子{ int x, y; printf("电脑落子:\n"); while (1) { x = rand() % rows; y = rand() % cols; if (board[x][y] == ' ') { board[x][y] = '#'; break; } }}5.最后就只剩判断输赢
先讨论玩家或者电脑赢的情况；代码如下；
char check_win(char board[ROWS][COLS], int rows, int cols)//判断输赢{ int i; for (i = 0; i < rows; i++) { if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ') return board[i][1]; } for (i = 0; i < cols; i++) { if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ') return board[1][i]; } if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ') return board[1][1]; else if (board[2][0] == board[1][1] && board[1][1] == board[0][2] && board[1][1] != ' ') return board[1][1]; else if (is_full(board, rows, cols)) return 'q'; return 0;}
这是考虑是平局的情况，平局则为棋盘下满都没有输赢，可以遍历整个数组（棋盘）若没有空格就为平局。代码如下；
static int is_full(char board[ROWS][COLS], int rows, int cols)//检测是否为平局{ int i, j; for (i = 0; i < rows; i++) { for (j = 0; j < cols; j++) { if (board[i][j] == ' ') return 0; } } return 1;}初步测试结果如下
代码如下；
void computer_move(char board[ROWS][COLS], int rows, int cols)//智能化电脑落子{ int x, y, i; printf("电脑落子:\n"); while (1) { x = rand() % rows; y = rand() % cols; for (i = 0; i < rows; i++) { if (board[i][0] == board[i][1] && board[i][0] == '#' && board[i][2] == ' ') { board[i][2] = '#'; goto flag1; } else if (board[i][1] == board[i][2] && board[i][1] == '#' && board[i][0] == ' ') { board[i][0] = '#'; goto flag1; } else if (board[i][0] == board[i][2] && board[i][2] == '#' && board[i][1] == ' ') { board[i][1] = '#'; goto flag1; } else if (board[0][i] == board[1][i] && board[0][i] == '#' && board[2][i] == ' ') { board[2][i] = '#'; goto flag1; } else if (board[1][i] == board[2][i] && board[1][i] == '#' && board[0][i] == ' ') { board[0][i] = '#'; goto flag1; } else if (board[0][i] == board[2][i] && board[2][i] == '#' && board[1][i] == ' ') { board[1][i] = '#'; goto flag1; } else if (board[0][0] == board[1][1] && board[0][0] == '#' && board[2][2] == ' ') { board[2][2] = '#'; goto flag1; } else if (board[1][1] == board[2][2] && board[1][1] == '#' && board[0][0] == ' ') { board[0][0] = '#'; goto flag1; } else if (board[0][0] == board[2][2] && board[0][0] == '#' && board[1][1] == ' ') { board[1][1] = '#'; goto flag1; } else if (board[0][2] == board[1][1] && board[1][1] == '#' && board[2][0] == ' ') { board[2][0] = '#'; goto flag1; } else if (board[1][1] == board[2][0] && board[1][1] == '#' && board[0][2] == ' ') { board[0][2] = '#'; goto flag1; } else if (board[2][0] == board[0][2] && board[2][0] == '#' && board[1][1] == ' ') { board[1][1] = '#'; goto flag1; } } for (i = 0; i < rows; i++) { if (board[i][0] == board[i][1] && board[i][0] == '*' && board[i][2] == ' ') { board[i][2] = '#'; goto flag1; } else if (board[i][1] == board[i][2] && board[i][1] == '*' && board[i][0] == ' ') { board[i][0] = '#'; goto flag1; } else if (board[i][0] == board[i][2] && board[i][2] == '*' && board[i][1] == ' ') { board[i][1] = '#'; goto flag1; } else if (board[0][i] == board[1][i] && board[0][i] == '*' && board[2][i] == ' ') { board[2][i] = '#'; goto flag1; } else if (board[1][i] == board[2][i] && board[1][i] == '*' && board[0][i] == ' ') { board[0][i] = '#'; goto flag1; } else if (board[0][i] == board[2][i] && board[2][i] == '*' && board[1][i] == ' ') { board[1][i] = '#'; goto flag1; } else if (board[0][0] == board[1][1] && board[0][0] == '*' && board[2][2] == ' ') { board[2][2] = '#'; goto flag1; } else if (board[1][1] == board[2][2] && board[1][1] == '*' && board[0][0] == ' ') { board[0][0] = '#'; goto flag1; } else if (board[0][0] == board[2][2] && board[0][0] == '*' && board[1][1] == ' ') { board[1][1] = '#'; goto flag1; } else if (board[0][2] == board[1][1] && board[1][1] == '*' && board[2][0] == ' ') { board[2][0] = '#'; goto flag1; } else if (board[1][1] == board[2][0] && board[1][1] == '*' && board[0][2] == ' ') { board[0][2] = '#'; goto flag1; } else if (board[2][0] == board[0][2] && board[2][0] == '*' && board[1][1] == ' ') { board[1][1] = '#'; goto flag1; } } if (board[x][y] == ' ') { board[x][y] = '#'; goto flag1; } }flag1:;}
效果如图；
