    Trouble printing tic tac toe

    Hello guys i have trouble printing tic tac toe display board.I am using putty to connect to my uni computers which run debian.
    Code:
    printf("\n");
    printf(" %c | %c | %c\n", a[0][0], a[0][1], a[0][2]);
    printf("---+---+---\n");
    printf(" %c | %c | %c\n", a[1][0], a[1][1], a[1][2]);
    printf("---+---+---\n");
    printf(" %c | %c | %c\n", a[2][0], a[2][1], a[2][2]);
    This is the way i use to print(the array includes 'X' and 'O' and in codeblocks it works the way i want but on terminal it doesnt.Any help appreciated.

    What is the output of the program when you run it from putty?

    it asks where to place the 'X' and the computer responds with 'O'.

    Sounds like it has nothing to do with the code posted then.

    So in what way does it "not work"? By output I mean something like what it looks like and why it is wrong

    Code:
    .X.|...|...
    ---+---+---
    ...|.O.|...
    ---+---+---
    ...|...|...
    That is an example output of the program snippet you showed, given appropriate values for the array - i'll use '.' to represent spaces. So what's wrong with it?

    Sorry,i found the problem.It is beacause i used '\0' for blank and it didnt work.Instead ' ' worked.If anyone could explain that would be nice.Thanks for the replys.

    Characters with values lower than 32 are control characters and trying to print them out may produce terminal-dependent behaviour. For example I notice that on Windows printing out a character with value 0 prints a space, but I don't see why all terminals would interpret it that way. If you want to print a space to the terminal, then print a space.

    Well '\0' means null, I believe null is a character that can occupy a space. (I'd suggest printing it out to test)

    By the way, isspace('\0') returns false, so at least the C standard library does not consider this character to be a valid space. It seems like only Windows considers it a valid space character. But like I said, if you want a space, then just print ' ' - what's the point of using something that only gives valid output on certain types of terminals when you can easily make it work on all terminals.
