more help...2d arrays in structures - sscanf

I'm reading in this file:

Code:

---

0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0
0  3  3  3  3  0  0  7  7  7  7  0  0 11 11 11 11  0  0 15 15 15 15  0
0  3  0  0  0  0  0  7  0  0  0  0  0 11  0  0  0  0  0 15  0  0 15  0

And i need to output it to my image.coords[][] 2d array. For example image.coords[0][k] would all be 0. image.coords[1][1] should be 3. Here's my code to do so, why is it outputting all 0's? I've been looking at it for a while, and the longer I look at it, the farther away I get to figuring it out. I'm guessing its some simple little error, but i can't figure it out.

Code:

---

    k = j = 0;
    while( fgets(buffer, MAXLINE, in) )
    {
        k=i=0;
        while(1)
        {
            while(!isspace(buffer[i]))
            {
                sscanf(buffer, "%d", &image.coords[j][k]);
                k++;
                i++;
            }
            while(isspace(buffer[i]))
            {
                i++;
            }
            if(buffer[i]=='\0')
            {
                break;
            }

            printf("%d ", image.coords[j][k]);

        }

        printf("\n");
        j++;
    }

Why are you incrementing both row and column any time you find a number?

I'm incrementing the buffer (i) and the column (k) whenever I find a number. I increment the row (j) at the very end, when the first while loop has to go to the top again.

Ah, right. I must have missed that due to your overly descriptive variable names. At any rate:

Code:

---

while(!isspace(buffer[i]))
            {
                sscanf(buffer, "%d", &image.coords[j][k]);

While we don't have a space at this particular character, read the first entry of the buffer over and over again into various spots in my 'coords' array.

Yeah that's my problem, I dunno how to assign say buffer[0], buffer[1], and buffer[2] to one array value instead of three. What should I do?

...a hint?...

Code:

---

#include <stdio.h>
#include <ctype.h>

int main(void) {
  int coords[7][24];
  char buffer[] = "0  3  3  3  0  0  0  7  7  7  0  0  0 11 11 11  0  0  0 15 15 15 15  0";

  char *pbuffer = buffer;
  int j,k;

      /* for row "j" */
      j = 3;
      for ( k=0 ; k<24 ; k++) {
        while(isspace(*pbuffer)) pbuffer++;
        sscanf(pbuffer, "%d", &coords[j][k]);
        while(isdigit(*pbuffer))  pbuffer++;
      }

      for ( k=0 ; k<24 ; k++) {
        printf(" %d",coords[j][k]);
      }

  return 0;
}

no b/c i'm going to be reading in different files, so i can't initialize the array to anything
