五子棋c语言实现
菜单打印函数
使用这个函数来接收用户选择的模式，并通过返回值返回。
逻辑是使用一个死循环来打印，根据玩家输入的数来判断进入什么模式，输入错误数字就不出循环，正确就出循环。
int menu() { int choice = -1; while (1) { printf("----------------欢迎使用五子棋------------------------\n"); printf("- 请选择模式 -\n"); printf("- 1.人-人对战游戏 -\n"); printf("- 2.人-机对战游戏 -\n"); printf("- 0.退出游戏 -\n"); printf("------------------------------------------------------\n"); printf("------------------------------------------------------\n"); scanf("%d", &choice); if (choice > 4 || choice < 0) printf("错误输入"); else break; } return choice; } 棋盘的初始化和打印
在这个函数中将表示棋盘的二维数组初始化为空状态，并通过棋盘数组的只来打印棋盘。打印棋盘时用到的符号：┏ ┳ ┓┣ ╋ ┫┗ ┻ ┛。要注意有些地方添加━和空格来控制打印的棋盘是正确的。
里面每一次打印都调用draw_chessman这个函数，在这个函数中将根据数组值来判断如何打印。
//绘制棋子 void draw_chessman(int type, char* tableline) { if (type == WHITE) printf(" ●"); if (type == BLACK) printf(" ○"); if (type == NO) printf("%s", tableline); } 打印棋盘的逻辑就是因为没能设置光标坐标那就只有一行一行打印然后根据边界行列值来判断。
如果要看如何打印改变光标可以参考这篇文章win32 API
void initMap(int map[N + 1][N + 1]) { //第一行和第一列显示数字 for (int i = 0; i < N + 1; i++) { map[0][i] = i; map[i][0] = i; if (i >= 10) { map[0][i] = i - 10; map[i][0] = i - 10; } } for (int i = 0; i < N + 1; i++) { //打印第一行数字 if (i == 0) { for (int j = 0; j < N + 1; j++) { printf("%-2d", map[0][j]); } printf("\n"); } //打印第一行棋盘 else if (i == 1) { for (int j = 0; j < N + 1; j++) { if (j == 0) printf("%d", map[i][j]); else if (j == 1) draw_chessman(map[i][j], " ┏"); else if (j == N) draw_chessman(map[i][j], "━┓"); else draw_chessman(map[i][j], "━┳"); } printf("\n"); } //打印最后一行 else if (i == N) { for (int j = 0; j < N + 1; j++) { if (j == 0) printf("%d", map[i][j]); else if (j == 1) draw_chessman(map[i][j], " ┗"); else if (j == N) draw_chessman(map[i][j], "━┛"); else draw_chessman(map[i][j], "━┻"); } printf("\n"); } else { for (int j = 0; j < N + 1; j++) { if (j == 0) printf("%d", map[i][j]); else if (j == 1) draw_chessman(map[i][j], " ┣"); else if (j == N) draw_chessman(map[i][j], "━┫"); else draw_chessman(map[i][j], "━╋"); } printf("\n"); } } } 人人对战
人人对战逻辑中就是先让黑方下棋，输入坐标，输入错误就再次输入（死循环实现），将该坐标的二维数组值变为黑，然后让其选择悔不悔棋，我实现的是只要1是悔棋其他数字就是不悔棋。执行完不悔棋后就判断是否胜利，如果胜就跳出选择是否重来一局，如果没胜就白棋下执行相同逻辑。
落子判空函数
在这个函数中判断坐标代表的二维数组值是不是空，不是就重新输入坐标。
void judgeEmpty(int map[][N + 1], int x, int y, int goal) { while (1) { if (map[x][y] != NO) { printf("已有棋子，重新输入\n"); scanf("%d%d", &x, &y); } else { map[x][y] = goal; initMap(map); break; } } } 悔棋函数
该函数里面就是根据用户选择，如果悔棋然后将刚才的地方的数组值变回空。
int retract(int map[][N + 1], int x, int y) { int choice = -1; printf("是否悔棋：是1\n"); scanf("%d", &choice); if (choice == 1) { map[x][y] = NO; initMap(map); } return choice; } 执行完不悔棋后就判断是否胜利
判胜负函数
这个函数就是将下的这个棋子的横竖斜方向判胜负。（没有判断和棋情况），如果要判断就是二维数组全不为空状态，使用遍历判断就行。
int judgeWin(int map[][N + 1], int x, int y) { for (int i = 1; i < N + 1; i++) { for (int j = 1; j < N + 1; j++) { if (j < N + 1 - 4 && (map[i][j] == BLACK || map[i][j] == WHITE))//横 { if (map[i][j] == map[i][j + 1] && map[i][j + 1] == map[i][j + 2] && map[i][j + 2] == map[i][j + 3] && map[i][j + 3] == map[i][j + 4]) return map[i][j]; } if (i < N + 1 - 4 && (map[i][j] == BLACK || map[i][j] == WHITE))//竖 { if (map[i][j] == map[i + 1][j] && map[i + 1][j] == map[i + 2][j] && map[i + 2][j] == map[i + 3][j] && map[i + 3][j] == map[i + 4][j]) return map[i][j]; } if (i < N + 1 - 4 && j < N + 1 - 4 && (map[i][j] == BLACK || map[i][j] == WHITE))//右下_ { if (map[i][j] == map[i + 1][j + 1] && map[i + 1][j + 1] == map[i + 2][j + 2] && map[i + 2][j + 2] == map[i + 3][j + 3] && map[i + 3][j + 3] == map[i + 4][j + 4]) return map[i][j]; } if (i > 4 && j > 4 && (map[i][j] == BLACK || map[i][j] == WHITE))//右上 { if (map[i][j] == map[i - 1][j - 1] && map[i - 1][j - 1] == map[i - 2][j - 2] && map[i - 2][j - 2] == map[i - 3][j - 3] && map[i - 3][j - 3] == map[i - 4][j - 4]) return map[i][j]; } } } return NO; } 人人对战
void peopleFight(int map[][N + 1]) { printf("--------人-人对战---------------\n"); initMap(map); while (1) { int x = -1; int y = -1; black: while (1) { printf("黑方落子\n"); printf("请输入要落下的坐标现在棋盘为%d*%d\n", N, N); scanf("%d%d", &x, &y); if (x < 0 || x > N || y < 0 || y > N) printf("错误输入\n"); else break; } judgeEmpty(map, x, y, BLACK); if (retract(map, x, y) == 1) goto black; //判断胜利 int ret = judgeWin(map, x, y); if (ret == BLACK) { printf("黑方获胜\n"); return; } else if (ret == WHITE) { printf("白方获胜\n"); return; } white: while (1) { printf("白方落子\n"); printf("请输入要落下的坐标现在棋盘为%d*%d\n", N, N); scanf("%d%d", &x, &y); if (x < 0 || x > N || y < 0 || y > N) printf("错误输入\n"); else break; } judgeEmpty(map, x, y, WHITE); if (retract(map, x, y) == 1) goto white; //判断胜利 ret = judgeWin(map, x, y); if (ret == BLACK) { printf("黑方获胜\n"); return; } else if (ret == WHITE) { printf("白方获胜\n"); return; } } } 人机对战
在这个函数中用户选择落子方，然后执行逻辑与人人对战一样。
但是电脑生成棋子提供两种选择：
一是将直接调用rand生成随机值，这就不可控
方法一这样写对棋子的位置生成是很不可控的，会让机器随机乱落子。
void machine(int map[][N + 1]) { printf("--------人-机对战---------------\n"); srand(time(NULL)); int choice = -1; printf("请输入你执黑棋还是白棋，黑1，白2\n"); scanf("%d", &choice); if (choice == 1) { while (1) { int x = -1; int y = -1; black: while (1) { printf("黑方落子\n"); printf("请输入要落下的坐标现在棋盘为%d*%d\n", N, N); scanf("%d%d", &x, &y); if (x < 0 || x > N || y < 0 || y > N) printf("错误输入\n"); else break; } judgeEmpty(map, x, y, BLACK); //判断胜利 int ret = judgeWin(map, x, y); if (ret == BLACK) { printf("黑方获胜\n"); return; } else if (ret == WHITE) { printf("白方获胜\n"); return; } if (retract(map, x, y) == 1) goto black; next: x = rand() % 15 + 1; y = rand() % 15 + 1; if (map[x][y] != NO) goto next; judgeEmpty(map, x, y, WHITE); //判断胜利 ret = judgeWin(map, x, y); if (ret == BLACK) { printf("黑方获胜\n"); return; } else if (ret == WHITE) { printf("白方获胜\n"); return; } } } else if (choice == 2) { while (1) { int x = -1; int y = -1; next2: x = rand() % 15 + 1; y = rand() % 15 + 1; if (map[x][y] != NO) goto next2; judgeEmpty(map, x, y, BLACK); //判断胜利 int ret = judgeWin(map, x, y); if (ret == BLACK) { printf("黑方获胜\n"); return; } else if (ret == WHITE) { printf("白方获胜\n"); return; } white: while (1) { printf("白方落子\n"); printf("请输入要落下的坐标现在棋盘为%d*%d\n", N, N); scanf("%d%d", &x, &y); if (x < 0 || x > N || y < 0 || y > N) printf("错误输入\n"); else break; } judgeEmpty(map, x, y, WHITE); //判断胜利 ret = judgeWin(map, x, y); if (ret == BLACK) { printf("黑方获胜\n"); return; } else if (ret == WHITE) { printf("白方获胜\n"); return; } if (retract(map, x, y) == 1) goto white; } } } 二是根据棋子赢面来判断哪里落子最好
这样实现就会让机器落子一直是去围堵你的棋子，虽然还是很垃圾，但是比方法一好多了。

主函数调用逻辑
用死循环调用，然后根据menu返回值通过switch-case来调用相应模式函数，最后在让用户选择是否再来一局，如果再来一局就不出循环，不再来就出循环。
int main() { while (1) { int map[N + 1][N + 1] = { 0 }; int choice = menu(); switch (choice) { case 1: //调用人人对打 peopleFight(map); break; case 2: //调用人机对打 machine(map); break; case 0: printf("退出成功\n"); exit(0); break; } int a = 0; printf("是否再来一盘：是1，不是0\n"); scanf("%d", &a); if (a == 0) break; } return 0; } 源代码
