I am trying to create a sudoku generator in turbo c++ for a project. This code is not working for some reason....Please help!

#include<iostream.h>
#include<conio.h>
#include<stdlib.h>

int chkcol(int u[x][y]);

int chkrow(int v[x][y]);

int chkbox(int w[x][y]);



void main()
{
  textcolor(WHITE);
  textbackgroundcolor(MAGENTA);
  clrscr();
  int sudoku[9][9];
  for(int i=0; i<9; i++)
   {
    for(int j=0; j<9; j++)
     {
      int check=0;
      randomize();
      while(check==0)
      {
       sudoku[i][j]==(random(9)+1)
       if (chkcol(A[i][j])=1 && chkrow(A[i][j])=1 && chkbox(A[i][j])=1)
       check++;
      }
     }
    }
  int puzzle[9][9];
  for(int k=0; k<=20; k++)
   {
    int count==0;
    randomize();

    if (puzzle[x][y]='\0')
    {puzzle[x][y]=sudoku[x][y];
    count++;}
    }
   }

try passing the arrays by pointer, and change == to =

ok ok sorry for lack of info....

#include<iostream.h>
#include<conio.h>
#include<stdlib.h>

int chkcol(int u[x][y]);[B]//size of the type is unknown or zero[/B]

int chkrow(int v[x][y]);[B]//size of the type is unknown or zero[/B]

int chkbox(int w[x][y]);[B]//size of the type is unknown or zero[/B]

Remove the x and y, leave the [] though.
