storage class errors

I've a quite a few functions in my project. so made a header file

Code:

#ifndef _check_H
#define _check_H

int BruteForceAlgo (void)
int check (int i, int j, int n);
int check_row (int i, int j, int n);
int check_column (int i, int j, int n);
int check_box_9x9 (int i, int j, int n);
int check_box_6x6 (int i, int j, int n);
int output (void);

#endif //_check_H

and my main.c file looks like this..

Code:

# include <stdio.h>
# include "check.h"

# define size 9 //array size
# define nmax 10 // max number in array [ 10 for 9x9, 7 for 6x6 ]

//global declaration
extern int sudoku[size][size];
extern int TempArr[size][size];
extern int I, J, N;
extern int dyN;
     
int main(void)
{
   int i,j;

   // Input 
   printf("Enter Sudoku\n");
   for (i=0; i<size; i++)
   {
       for (j=0; j<size; j++) 
       {
            scanf("%d",&sudoku[i][j]);
            //copy to TempArr
            TempArr[i][j] = sudoku[i][j];
...............

I've even specified # include "check.h" in function all function files...

- As I require scope of some identifiers in other function files, I mentioned extern

This problem is I'm getting the following errors:

PHP Code:

storage class specified for parameter `sudoku' 
storage class specified for parameter `TempArr' 
storage class specified for parameter `I' 
storage class specified for parameter `J' 
storage class specified for parameter `N' 
storage class specified for parameter `dyN' 

syntax error before '{' token 
[Build Error]  [main.o] Error 1 


Atleast I had idea about 'storage class' errors but I couldn't understand the last two errors..

I don't know why "syntax error before '{' token " is coming ...

help me.

I'm currently using Windows XP with Dev-C++ IDE

Based on your error messages, I believe that the errors are in code that you did not show. You probably have one or more functions where you used extern in the parameter list. Remove those uses of extern.

By last two errors you probably mean:

Code:

syntax error before '{' token 
[Build Error]  [main.o] Error 1

The first line is an error message, the second line is just an IDE generated notification that the build failed. The error message itself is self-explanatory: there was a syntax error before the '{' token.

Also, note that your error messages probably have line numbers that you removed when posting.

I could resolve all other errors.. but not this..
22 D:\Dev-Cpp\sudoku\main.c syntax error before '{' token

I am not able to understand where the error is exactly above {

this is my main file..

Code:

# include <stdio.h>
# include "check.h"

# define size 9 //array size
# define nmax 10 // max number in array [ 10 for 9x9, 7 for 6x6 ]

// global variables.
   int sudoku[size][size];
   int TempArr[size][size];
   int I, J, N;
   int dyN;
   
int main(void)
{
   int i,j;
   // Input 
   printf("Enter Sudoku\n");
   for (i=0; i<size; i++)
   {
       for (j=0; j<size; j++) 
       {
            scanf("%d",&sudoku[i][j]);
            //copy to TempArr
            TempArr[i][j] = sudoku[i][j];
       }    
   }
   printf("Thanks for entering\n");

   BruteForceAlgo();     
   output();
   
   system ("pause");
   return 0;
}// main
