三子棋游戏
问题描述：
3*3的棋盘中，只要一条线上出现三个一样的棋子就获胜（玩家或电脑）；如果棋盘已经放满还未出现三个棋子一条线则打成平手。
具体细节：
-
初始化棋盘(用空格初始化)
//初始化棋盘 void initChess(char chessbox[ROW][COL]){
1for (int row = 0; row < ROW; row++){ 2 3 4 for (int col = 0; col < COL; col++){ 5 6 7 chessbox[row][col] = ' '; 8 } 9}}
-
打印棋盘
//打印棋盘 void printChess(char chessbox[ROW][COL]){
1system("cls"); 2printf("+---+---+---+\n"); 3for (int row = 0; row < ROW; row++){ 4 5 6 printf("| %c | %c | %c |\n", 7 chessbox[row][0], chessbox[row][1], 8 chessbox[row][2]); 9 printf("+---+---+---+\n"); 10}}
-
电脑落子(用o表示电脑落子)
//电脑落子(用o表示) void computerMove(char chessbox[ROW][COL]){
1srand(time(0)); 2while (1){ 3 4 5 int row = rand() % 3; 6 int col = rand() % 3; 7 if (chessbox[row][col] == ' '){ 8 9 10 chessbox[row][col] = 'o'; 11 break; 12 } 13 14}}
-
玩家落子
//玩家落子(用x表示) void playerMove(char chessbox[ROW][COL]){
1int row, col; 2while (1){ 3 4 5 printf("请输入您的落子地点:"); 6 scanf("%d %d", &row, &col); 7 if (row >= 3 || col >= 3){ 8 9 10 printf("您输入的落子位置有误,请重新输入:"); 11 continue; 12 } 13 if (chessbox[row][col] == ' '){ 14 15 16 chessbox[row][col] = 'x'; 17 break; 18 } 19 printf("该位置已有棋子,请重新输入:"); 20}}

三个棋子一条线
-
在一行或一列实现三个棋子一条线
//行 for (int row = 0; row < ROW; row++){
1 if (chessbox[row][0] != ' ' 2 &&chessbox[row][0] == chessbox[row][1] 3 && chessbox[row][0] == chessbox[row][2]){ 4 5 6 return chessbox[row][0]; 7 } 8} 9//列 10for (int col = 0; col < COL; col++){ 11 12 13 if (chessbox[0][col] != ' ' 14 &&chessbox[0][col] == chessbox[1][col] 15 && chessbox[0][col] == chessbox[2][col]){ 16 17 18 return chessbox[0][col]; 19 } 20} -
对角线实现三个棋子一条线
if (chessbox[0][0] != ' ' &&chessbox[0][0] == chessbox[1][1] && chessbox[0][0] == chessbox[2][2]){
1 return chessbox[0][0]; 2} 3if (chessbox[2][0] != ' ' 4 &&chessbox[2][0] == chessbox[1][1] 5 && chessbox[2][0] == chessbox[0][2]){ 6 7 8 return chessbox[2][0]; 9}
- 和棋
-
棋盘放满还未获胜，则为和棋，打成了平手。
在这里插入代码片 //和棋 if(isFull(checkbox)){
1 return 'a'; 2 }
- 输赢约定：
-
返回x代表玩家获胜
if (isWinner(chessbox) == 'x'){
1 printf("恭喜您赢啦!\n"); 2 break; 3 } -
返回o代表电脑获胜
if (isWinner(chessbox) == 'o'){
1 printf("很遗憾,您输了!\n"); 2 break; 3 } -
返回a代表和棋（打成平手）
if (isWinner(chessbox) == 'a'){
1 printf("你和电脑同一水平呦!\n"); 2 break; 3 }
- 判断棋盘是否放满：
-
返回1代表棋盘已满
-
返回0代表棋盘未满
//判断棋盘是否摆满 //1表示满;0表示不满。 int isFullChess(char chessbox[ROW][COL]){
1for (int row = 0; row < ROW; row++){ 2 3 4 for (int col = 0; col < COL; col++){ 5 6 7 //找到空格,说明未满 8 if (chessbox[row][col] == ' '){ 9 10 11 return 0; 12 } 13 } 14} 15return 1;}
