Thread: Syntax error before ']' token (2D array for tic tac toe simulation)

Hi guys,
I am working with a 2D array in C for the first time. I have the following syntax error 4 times in code:

Code:

Syntax error before ']' token

Here is part of the code (I don't want to post all of it because it is a HW assignment)

Code:

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>

//Declare Global Constants
#define ROWS 3
#define COLS 3

//Declare Functions
bool getInput(int* inpt);
void generateBoard(int inpt, int board [][COLS]);
void printBoard(int board [] [COLS]);
bool isValid(int board [] [COLS]);
bool isWinner (int board [][COLS], int* winpat, int* winsum);
void printWinner(int board [][COLS], int winpat, int winsum);
int main (void)
{
   //Declare Local Variables
   int inpt, winpat, winsum = 0; 
   int board [2][2];
   bool isGdInpt, isBrdVld, isAWinner;
   
   //Call fuctions
   FILE *fpIn, *fpOut;
   isGdInpt = getInput(&inpt);
   if(isGdInpt)
   {
      generateBoard(inpt, board [][]);
      isBrdVld = isValid(board [][]);
      if(isBrdVld)
      {
         isAWinner = isWinner(board[][], &winpat, &winsum);
         if(isAWinner)
            printWinner(board [][], winpat, winsum);
         else
            fprintf(fpOut, "There is no winner this round.");
      }
      fclose(fpOut);
   }
   else
   printf("\n\n");
   
   //End program
   return 0;
}

I just need to know how to fix the syntax errors. Thanks in advance to anyone who helps me out.

You do NOT call a function with empty square braces.
You either fill them or remove them.

Code:

generateBoard(inpt, board [][]);

What is board[][]? When you use board as an actual parameter, you send the function an address of an element of the 2D array. board or board[0][0], the two are essentially equivalent.

Thanks for your help; I was able to fix the code and it works great!
