Борьба с TicTacToe в C

Я попытался запрограммировать простой TicTacToe в C. Сама программа компилирует и не показывает ошибок. Итак, программа рисует поле, читает имена и позволяет игроку помещать свой символ в определенное поле. Все это происходит в цикле while, его следует запускать до тех пор, пока не выиграет ничья или кто-то победит. Но программа просто запускает цикл один раз, поэтому есть только один ход, затем программа останавливается.Борьба с TicTacToe в C

Так вот мой код:

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 Headerfile:

#include <stdio.h> 
#include <stdlib.h> 
#include <string.h> 
#include <time.h> 
#define NAMELENGTH 20 
#pragma warning(disable:4996) 

extern void drawField(char *field); 
extern void getnames(char nameField[][NAMELENGTH]); 
extern void initField(char *field); 
extern void turn(char actualPlayer, char names[][NAMELENGTH], char *field); 
extern char isWinner(char actualPlayer, char *field); 
extern void printwinner(char winnerNumber, char names[][NAMELENGTH]); 
extern void printDrawGame(char names[][NAMELENGTH]); 
extern double get_random_number();

, а затем мой game.c где я определил свои функции:

#include <stdio.h> 
#include <stdlib.h> 
#include <string.h> 
#include <time.h> 
#include "game.h" 
#define NAMELENGTH 20 
#pragma warning(disable:4996) 

void drawField(char *field) { 

printf("________________________\n"); 
printf("|  |  |  |\n"); 
printf("| %c | %c | %c |\n", field[0], field[1], field[2]); 
printf("|_______|_______|______|\n"); 
printf("|  |  |  |\n"); 
printf("| %c | %c | %c |\n", field[3], field[4], field[5]); 
printf("|_______|_______|______|\n"); 
printf("|  |  |  |\n"); 
printf("| %c | %c | %c |\n", field[6], field[7], field[8]); 
printf("|_______|_______|______|\n"); 

} 

void getnames(char nameField[][NAMELENGTH]) { 

printf("Name of the first player: "); 
scanf("%s", nameField[0]); 
printf("Name of the second player: "); 
scanf("%s", nameField[1]); 

} 

void initField(char *field) { 

for (int i = 0; i <= 8; i++) 
{ 
    field[i] = i + '1'; 
} 

} 

void turn(char actualPlayer, char names[][NAMELENGTH], char *field) { 

char symbol = ' '; 
int p1fieldnumber; 
int p2fieldnumber; 


if (actualPlayer == 0) 
{ 
    do { 

     printf("\nIts Player %s's turn.", names[0]); 
     char symbol = 'X'; 
     printf("\nNumber of the field which you want to put your symbol in: "); 
     scanf("%d", &p1fieldnumber); 
     if (field[p1fieldnumber] == 'X' || field[p1fieldnumber] == 'O') 
     { 
      printf("\nField is already occupied!"); 
      p1fieldnumber = 10; 
     } 
    } while (p1fieldnumber < 1 || p1fieldnumber > 9); 

    field[p1fieldnumber-1] = 'X'; 

} 
else { 

    do { 
     printf("\nIts Player %s's turn.", names[1]); 
     char symbol = 'O'; 
     printf("\nNumber of the field which you want to put your symbol in: "); 
     scanf("%d", &p2fieldnumber); 
     if (field[p2fieldnumber] == 'X' || field[p2fieldnumber] == 'O') 
     {

      p2fieldnumber = 10; 
     } 
    } while (p2fieldnumber < 1 || p2fieldnumber > 9); 

    field[p2fieldnumber-1] = 'O'; 

} 

}

Существует множество е вопросы

isWinner возвращает символы '0', '1', '2' и '3'. Замените их цифрами 0, 1, 2, 3, потому что вы сравниваете их с цифрами в main.
В main вместо проверки if (winner >= 1) {, что верно, даже если 3 возвращается isWinner, проверьте if (winner == 1 || winner == 2) {.
Предлагаем использовать круглые скобки в isWinner вокруг каждого условия, разделенного ||.

Скобки, как показано ниже для первого условия

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')))
