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.

    {'1', '2', '3'},

    {'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'},

CodePudding user response：

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.

CodePudding user response：

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
