array printing

Hey guys i want to be able to print whatever is inside that array how many times the user inputs. For example user types in 2 i want it to display 2 rows and 2 columns. Or types in 3 i want it to display 3 rows and 3 columns. The array holds '?' up to 16 of them. i sorta done a little bit of it but stuck

if user selects 3

? ? ?
? ? ?
? ? ?

if user selects 2
? ?
? ?

Code:

#define MAX_GRID 16
#define BLANK ''
#define UNKNOWN '?'

void printGridMineSize(char displayGrid[MAX_GRID][MAX_GRID], unsigned size, int getMineSize)
{
    int i=0;
    int k=0;
    
    
  
    printf("-------------------\n");
    
    for(i=0; i<size; i++)
    {
    
        for(k=0; k<size; k++)
	{
	   
	  printf("  %c     \n",displayGrid[i][k]); 
	  
	  printf(" +---+\n");      
	
	}
	printf("\n");
    
    }
   

}

void init(char minefield[MAX_GRID][MAX_GRID], 
          char displayGrid[MAX_GRID][MAX_GRID])
{
   int i;
   int j;

   for(i=0; i<MAX_GRID; i++)
   {

      for(j=0; j<MAX_GRID; j++)
      {
         minefield[i][j] = BLANK;
         displayGrid[i][j] = UNKNOWN;
         
         
      }

   }


}

what are you "stuck" on? It looks ok to me. It may not be a very readable format, but the grid elements should be ok.

Code:

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


#define MAX_GRID 16
#define BLANK ''
#define UNKNOWN '?'

void printGridMineSize(char displayGrid[][MAX_GRID], unsigned size, int getMineSize)
{
    int i=0;
    int k=0;
    
    
  
    printf("-------------------\n");
    
    for(i=0; i<size; i++)
    {
    
        for(k=0; k<size; k++)
	{
	   
	  printf("  %c     ",displayGrid[i][k]); 
	  
	 // printf(" +---+\t");      NOTE
	
	}
	printf("\n");
    
    }
   

}

void init( char minefield[][MAX_GRID], 
          char displayGrid[][MAX_GRID])
{
   int i;
   int j;

   for(i=0; i<MAX_GRID; i++)
   {

      for(j=0; j<MAX_GRID; j++)
      {
         minefield[i][j] = BLANK;
         displayGrid[i][j] = UNKNOWN;
         
         
      }

   }


}

main(){
char minefield[MAX_GRID][MAX_GRID];
char displayGrid[MAX_GRID][MAX_GRID];
init(minefield,displayGrid);
printGridMineSize(displayGrid,4,2);
}
