I think you do not understand how to use pointer.
I propose to try to find some easier way to get what you want to do
instead of using pointer.

#include <stdio.h>
#define columns  8
#define rows  8

int map [columns][rows] ={0};
int mask[columns][rows] ={0};

void initarray(int [columns][rows]); 
void display  (int [columns][rows]);

int main(int argc, char *argv[])
{
   int x,y;
   for ( y = 0; y < rows;y++)
     for (x=0;x<columns;x++){
       map [x][y] = x;
       mask[x][y] =x*2;
     }
   display(map);
   display(mask);
   return 0;
}
 
void display(int arr [columns][rows])
{
 int x,y;
 for (y=0; y<rows; y++){
   for (x=0; x < columns; x++) printf("%3d",arr[x][y]);
   puts("");
 }
 puts("");
