this doesnt do what i want it to do

Code:

---

#include<stdio.h>


int
main(void)
{
 char tic_tac_toe[3][3] =
        {{' ', ' ', ' '}, {' ', ' ', ' '}, {' ', ' ', ' '}};

 char i, j;

  for (i=1; i<=3; i=i+1){
      for (j=1; j<=3; j=j+1)
      {
          printf("Please enter symbol in position %d, %d\n",i,j);
          scanf("%", &tic_tac_toe[i][j]);
          scanf("%*[^\n]");
          scanf("%1[\n]");
      }
      }

void print_board (char tic_tac_toe[3][3]){
  int i,j;
  for (i = 0; i < 3; i++){
    for (j = 0; j < 3; j++){
      printf("%c\t", tic_tac_toe[i][j]);
    }
    printf("\n");
  }

}


int has_won (char tic_tac_toe[3][3]){

  if (tic_tac_toe[0][0] == tic_tac_toe[0][1] &&
      tic_tac_toe[0][1] == tic_tac_toe[0][2]){
    printf("%c has won!\n", tic_tac_toe[0][0]);
    return 1;
  }
  else if (tic_tac_toe[2][0] == tic_tac_toe[2][1] &&
          tic_tac_toe[2][1] == tic_tac_toe[2][2]){

*what did you want it to do
*where do you think it's going wrong
*you need a better thread title
*why are you posting c code on the C++ board?

Psst, this isn't the C++ board.

i need it to print out a tictactoe board

i have no clue where i went wrong, it just doesnt print the board after the player puts in letters at the coordinates

> for (i=1; i<=3; i=i+1)
Arrays start at 0, not 1

> scanf("%", &tic_tac_toe[i][j]);
You need to work on your use of scanf - two of the calls are broken.
This one for example does NOT read a char (or anything else)

> void print_board (char tic_tac_toe[3][3])
1. It seems to be declared inside main - C doesn't have nested functions
2. You don't have a prototype for it.
3. You don't call it from main.

there are still random things that i dont understand about some of the parts in this program so for those parts i copied from basic examples in my textbook and made my own ideas on how to apply them to this program

tell me if im getting warmer

Your input function writes past the bounds of the array.
Arrayindexes in c/c++ range from 0 to num-1 ( 0..2 in your case ).
Your print_board() function would print only a 2x2 board ( you use indexes from 1 to 2 )

EDIT: just noticed Salem has already told you all of this

> tell me if im getting warmer
Nope - you're getting further away.
Sure you fixed the nested function problem, but you added some more problems along the way, like breaking the print_board() function.

Code:

---

scanf("%", &tic_tac_toe[i][j]);

---

% what?

theman29, Please

1) give an explanation what these 4 lines do in general, then
2) what each line specifically does -- in detail. I'd like to know what you are thinking:

Code:

---

printf("Please enter symbol in position %d, %d\n",i,j);
scanf("%", &tic_tac_toe[i][j]);
scanf("%*[^\n]");
scanf("%1[\n]");

---

3) Have youe ever heard of the function getchar()?

Quote:

---

3) Have youe ever heard of the function [i]getchar()?

---

Code:

---

user@0[~]$ man [i]getchar
No manual entry for [i]getchar
user@0[~]$

---

Nope. :D

Code:

---

          printf("Please enter symbol in position %d, %d\n",i,j);
          scanf("%", &tic_tac_toe[i][j]);
          scanf("%*[^\n]");
          scanf("%1[\n]");

---

I suspect you're trying to do something like this:

Code:

---

          printf("Please enter symbol in position %d, %d\n",i,j);
          scanf("%c", &tic_tac_toe[i][j]);
