Keener_Tic_Tac_Toe（井字棋游戏）代码(c语言）

遇到的问题:

1.中间有需要清楚键盘缓冲区,具体(?)

2.number char型,强制int型转换是利用ASCII码,相差48.

3.string型c++支持,c并没有,利用char型字符数组解决,char player1[20];scanf("%s",player1);printf("%s",player1);

代码如下:

1. 
   
2. #include <stdio.h>
3. #include <ctype.h>
4. #include <stdbool.h>
5. #include <stdlib.h>
6. #include <time.h>
9. int main(){
11. //初始化
12. char another_game = 'Y';
13. char game[3][3] = {{'1','2','3'},{'4','5','6'},{'7','8','9'}};
14. bool win = true;
15. int choose_player = 0;
16. char number = '0';
17. int row = 0 , col = 0;
18. bool take_turns = false;
19. char player1[20],player2[20];
20. int c;
22. //循环_1
23. do{
24. //初始化游戏
25. printf("井字棋游戏初始化...");
26. char game[3][3] = {{'1','2','3'},{'4','5','6'},{'7','8','9'}};
27. win = false;
29. //输入玩家1,2姓名
30. printf("(不要使用空格,回车键结束)");
31. printf("请输入玩家1姓名:");
32. scanf("%s",player1);
33. printf("请输入玩家2姓名:");
34. scanf("%s",player2);
36. //随机选择先落子玩家
37. srand((unsigned)time(NULL));
38. choose_player = rand()%2 + 1;
39. if(choose_player == 1){
40. take_turns = true;
41. printf("%s(玩家1)首先落子(1~9).",player1);
42. }else{
43. take_turns = false;
44. printf("%s(玩家2)首先落子(1~9).",player2);
45. }
47. //循环_2
48. while(!win){
49. //输出3x3游戏格
50. printf("");
51. printf(" %c | %c | %c ",game[0][0],game[0][1],game[0][2]);
52. printf("---+---+---");

59. //玩家1,玩家2分别下棋
60. //落子是否有效
61. do{
62. printf("%s落子:",take_turns?player1:player2);
63. //这里需要清楚缓冲区(why?)
64. if(feof(stdin) || ferror(stdin)){
65. break;
66. }
67. while((c = getchar()) != '' && c != EOF);
68. scanf("%c",&number);
70. //why:ASCII码表对应的数字差48~
71. row = ((int)number-48-1)/3;
72. col = ((int)number-48-1)%3;
73. //printf("%d.%d.%c.",row,col,game[row][col]);
74. //printf("%c",number);
75. }while( game[row][col] != number);
77. //更新棋盘
78. if(take_turns){
79. game[row][col] = 'X';
80. }else{
