Tic Tac Toe game - c

Question

I was working on learning c code and was making a tic-tac-toe game. The Boolean issue was fixed. Now the issue is that it is looping the printf("There is no empty space!"); and prinf("Invalid !!!"); after it take the player1 name. I also wanted to know if the line where I printed the array with the grid is correct or not.
#include <stdio.h>
#include <stdlib.h>
#include <strings.h>
char space[3][3] = {
{'1', '2', '3'},
{'4', '5', '6'},
{'7', '8', '9'},
};
int row;
int column;
char token = 'x';
bool tie = false;
char n1[256];
char n2[256];
void functionboard()
{
char space[3][3] = {
{'1', '2', '3'},
{'4', '5', '6'},
{'7', '8', '9'},
};
printf(" | | \n");
printf(" ", space[0][0], "| ", space[0][1], "| ", space[0][2], " \n");
printf("______|________|_____\n");
printf(" | | \n");
printf(" ", space[1][0], " | ", space[1][1], " | ", space[1][2], " \n");
printf("______|________|_____\n");
printf(" | | \n");
printf(" ", space[2][0], " | ", space[2][1], " | ", space[2][2], " \n");
printf(" | | \n");
}

Answer 1

If the error you're getting is about the type bool and not the variable itself, see this question: you need to also include <stdbool.h> to be able to use the bool type.

Answer 2

There's no built-in bool type in classic C. You can use it though by using #include <stdbool.h>. The other solution is replacing it with an int since it can be used like a bool
