一.菜单。
二.游戏代码。
三.胜负判断。
四.三子棋实现。
下列代码所需要的头文件及宏定义
{ #define ROW 3 #define COL 3 #include <stdio.h> #include <stdlib.h> #include <time.h> } 一.菜单（菜单的实现，是否玩游戏） int menu() { printf("--------------------------\n"); printf("--------1.开始游戏--------\n"); printf("--------0.退出游戏--------\n"); printf("--------------------------\n"); int choice = 0; printf("请输入你的选择："); scanf("%d", &choice); return choice; }
二.游戏代码
1.棋盘的打印
3*3的数组定义为空格：
void init(char chessBoard[ROW][COL])
{
for (int row = 0; row < ROW; row++)
{
for (int col = 0; col < COL; col++)
{
chessBoard[row][col] = ' ';
}
}
}
棋盘格子打印：
void chessBoard_print(char chessBoard[ROW][COL])
{
for (int row = 0; row < ROW; row++)
{
printf(" %c | %c | %c |\n", chessBoard[row][0], chessBoard[row][1], chessBoard[row][2]);
printf("---+---+---+\n");
}
}
2.玩家下棋
void playerMove(char chessBoard[ROW][COL])
{
while (1)
{
int row = 0;
int col = 0;
scanf("%d %d", &row, &col);
if (row < 0 || row >= ROW || col < 0 || col >= COL)
{
printf("您的坐标不在合法范围内 [0, 2],请重新输入：\n");
continue;
}
if (chessBoard[row][col] != ' ')
{
printf("请重新下旗子!\n");
continue;
}
chessBoard[row][col] = 'x';
break;
}
}
3.电脑下棋
void computerMove(char chessBoard[ROW][COL])
{
while (1)
{
int row = rand() % ROW;
int col = rand() % COL;
if (chessBoard[row][col] != ' ')
{
continue;
}
chessBoard[row][col] = 'o';
break;
}
}
4.判断是否此处可以落子
int isFull(char chessBoard[ROW][COL])
{
for (int row = 0; row < ROW; row++)
{
for (int col = 0; col < COL; col++)
{
if (chessBoard[row][col] == ' ')
{
return 0;
}
}
}
return 1;
}
5.主体
void game() { char chessBoard[ROW][COL] = { 0 }; init(chessBoard); char winner = ' '; while (1) { chessBoard_print(chessBoard); playerMove(chessBoard); winner = isWin(chessBoard); if (winner != ' ') { break; } computerMove(chessBoard); winner = isWin(chessBoard); if (winner != ' ') { break; } } chessBoard_print(chessBoard); if (winner == 'x') { printf("恭喜您, 您赢了!\n"); } else if (winner == 'o') { printf("你输了!\n"); } else { printf("平局\n"); } }
三.胜负判断
char isWin(char chessBoard[ROW][COL]) { for (int row = 0; row < ROW; row++) { if (chessBoard[row][0] != ' ' && chessBoard[row][0] == chessBoard[row][1] && chessBoard[row][0] == chessBoard[row][2]) //（判断行） { return chessBoard[row][0]; } } for (int col = 0; col < COL; col++) { if (chessBoard[0][col] != ' ' && chessBoard[0][col] == chessBoard[1][col] && chessBoard[0][col] == chessBoard[2][col])//（判断列） { return chessBoard[0][col]; } } if (chessBoard[0][0] != ' ' && chessBoard[0][0] == chessBoard[1][1] && chessBoard[0][0] == chessBoard[2][2])//（左交叉） { return chessBoard[0][0]; } if (chessBoard[2][0] != ' ' && chessBoard[2][0] == chessBoard[1][1] && chessBoard[2][0] == chessBoard[0][2])//（右交叉） { return chessBoard[2][0]; } if (isFull(chessBoard))//（和棋） { return 'heqi'; } return ' '; }
四.三子棋实现。
1.主函数
int main() { srand((unsigned int)time(NULL)); while (1) { int choice = menu(); if (choice == 1) { game(); } else if (choice == 0) { printf("退出游戏!\n"); break; } else { printf("输入错误！请重新输入！\n"); continue; } } return 0; }
2.实现图示。
