在 C 中与 TicTacToe 斗争
Struggling with TicTacToe in C
我尝试用 C 编写一个简单的 TicTacToe。程序本身编译并且没有显示错误。
所以程序绘制场地，读取名称并让玩家将他的符号放在特定的场地中。所有这一切都发生在一个 while 循环中，应该是 运行 直到它平局或有人赢了。
但是程序只是 运行 循环一次所以只有一圈然后程序停止。
所以这是我的代码：
main.c:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "game.h"
#define NAMELENGTH 20
int main(void) {
char names[2][NAMELENGTH];
// field positions
char field[9];
int winner = -1;
getnames(names);
printf("\n\n");
initField(field);
// set field positions to 'empty'
char actualPlayer = (char)(get_random_number()*10.0) % 2;
while (1) {
drawField(field);
turn(actualPlayer, names, field);
winner = isWinner(actualPlayer, field);
drawField(field);
if (winner >= 1) {
printwinner(winner, names);
return 0;
}
else if (winner == 0) {
printDrawGame(names);
return 0;
}
actualPlayer = (actualPlayer + 1) % 2;
}
return 0;
}
game.h 头文件：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#define NAMELENGTH 20

存在多个问题
isWinner returns 个字符“0”、“1”、“2”和“3”。将它们替换为数字 0、1、2、3，因为您正在与 main.
在 main 而不是检查 if (winner >= 1) {，即使 isWinner 返回 3 也是如此，检查 if (winner == 1 || winner == 2) {.
建议在isWinner中用括号括起每个条件，用||分隔。
第一个条件括号如下所示
if (((field[0] == 'O') && (field[1] == 'O') && (field[2] == 'O')) ||
((field[3] == 'O') && (field[4] == 'O') && (field[5] == 'O')) ||
((field[6] == 'O') && (field[7] == 'O') && (field[8] == 'O')) ||
((field[0] == 'O') && (field[4] == 'O') && (field[8] == 'O')) ||
((field[2] == 'O') && (field[4] == 'O') && (field[6] == 'O')) ||
((field[0] == 'O') && (field[3] == 'O') && (field[6] == 'O')) ||
((field[1] == 'O') && (field[4] == 'O') && (field[7] == 'O')) ||
((field[2] == 'O') && (field[5] == 'O') && (field[8] == 'O')))
