Thread: 2 Dimensional Array Nightmare.

This is going to be a time consuming long post. I apologise. But this has been a problem that has plagued me for days.

This is my grid:

Code:

...........#.#.
.#.#.#.#.#.....
...........#.#.
.#.#.#.###.#.#.
.....#.........
.#.#.#.#.###.##

I am supposed to count and number both the columns and the rows.

* Rule for Column:
There has to be 3 consecutive dots on the grid in a column.
So this is the output i should get.

Code:

1.2.3.4.5.6#7#8
.#.#.#.#.#.....
...........#.#.
9#10#11#12###.#13#.
.....#.........
.#.#.#.#.###.##

* Rule for Rows:
There has to be 3 or more consecutive dots from left to right for there to be a row (bound by hashes or end of line. Here's the output that i get.

Code:

1..........#.#.
.#.#.#.#.#2....
3..........#.#.
.#.#.#.###.#.#.
4....#5........
.#.#.#.#.###.##

Everything's cool so far. But the problem is that i need an output that is a combination of BOTH the GRIDS shown above. The Row Grid and the Column Grid. This is the output i need to get:

Code:

1.2.3.4.5.6#7#8
.#.#.#.#.#9....
10..........#.#.
11#12#13#14###.#15#.
16....#17........
.#.#.#.#.###.##

I don't know how to GET THIS output and get the numbers right.

Should i be using another array to do this? Any Help Appreciated.

Thanks guys.



Here's part of my code used to number the grids:

Code:

// For numbering COLUMNS

  countcolumn = 1;
  for(row=0; row<tall; row++){
    for(col=0; col<wide; col++){
      if ((row%3==0) && (grid[row][col]=='.') && (grid[row+1][col]=='.') && (grid[row+2][col]=='.')){
	printf("%d", countcolumn++);
      }
      else{
	printf("%c", grid[row][col]);
      }
    }
    printf("\n");
  }

  printf("\n");
  printf("\n");

// for Numbering ROWS.

  countrow = 1;
  row      = 0;
  col      = 0;
  onoroff     = 0;

  for(row=0; row<tall; row++){
    for(col=0; col<wide; col++){
  
      if ((grid[row][col]=='.') && (grid[row][col+1]=='.') && (grid[row][col+2]=='.')){
	if (onoroff==0){
	  printf("%d", countrow++);
	  onoroff = 1;
	  continue;
	}
	printf("%c", grid[row][col]);
      }
      else{
	printf("%c", grid[row][col]);
	flag = 0;
      }
    
    }
    printf("\n");
  }

Hey thanks for that. That was really neat code. Except for one

The code below makes it so that the only thing that Column counting is only done in r%3 and row counting is done in all the other rows.

Whereas what i need to do is to have row counting done in all rows including r%3 and column counting only in r%3.

Code:

for ( r = 0 ; r < ROWS ; r++ ) {
        if ( r % 3 == 0 ) label_columns(r);
        else label_rows(r);
        printf( "\n" );

I tried to change the code to

Code:

if (r%3== 0){
label_columns(r);
label_rows(r);
printf("\n");

But this messes up entirely. adds new characters the numbers get messed up etc.


To Test this. I have made up a new grid.

Code:

NEW GRID

...............
............##.
#.#.#.##.#.##.#
...............
###############
..#..#..#..#..#

The Output that i get from my code for this grid:

Code:

COLUMNS:

.1.2.3..4.5....
............##.
#.#.#.##.#.##.#
...............
###############
..#..#..#..#..#

ROWS:

1..............
2...........##.
#.#.#.##.#.##.#
3..............
###############
..#..#..#..#..#

The Output that i get from your code:

Code:

.1.2.3..4.5....
6...........##.
#.#.#.##.#.##.#
...............
###############
..#..#..#..#..#

The output that i desired (COMBINED Row and Column Numbering):

Code:

12.3.4..5.6....
7...........##.
#.#.#.##.#.##.#
8..............
###############
..#..#..#..#..#

I am not really sure how to accomplish this. hmmmm..
