How do you copy a file into a 2-dimensional array?

How do you copy a file into a 2-dimensional array?

How do you copy a file into a 2-dimensional array?

(OP)
Anybody know how to do that?

RE: How do you copy a file into a 2-dimensional array?

Can you be more specific?
What does the file contains?

RE: How do you copy a file into a 2-dimensional array?

You shuld be more specific on this.
Suppose if the file contains number like this,
1 2
3 4
5 6
You can use a loop like this.

while( !feof(fileptr))
{
  fscanf(fileptr, "%d %d", &arr[0], &arr[1]);
  ++i;
}

I hope this helps.

Cheers,

RE: How do you copy a file into a 2-dimensional array?

Basking got caught by the TGML processor which wiped out his [i]'s ;) -- I added a little more detail to it his code as well:

#define NUM_ROWS    3
#define NUM_COLS    2

...

int i=0;
int arr[NUM_ROWS][NUM_COLS];

while(i<NUM_COLS && !feof(fileptr))
{
  /* check here to make sure fscanf agrees with us */
  if (fscanf(fileptr, "%d %d", &arr[i][0], &arr[i][1])!=NUM_COLS) {
    fprintf(stderr,"Bad file\n");
    break;
  }
  ++i;
}

This is a naive implementation (the array is of a fixed size, limiting the # of columns and rows allowed) but since you didn't provide very much information on what you want to do, it's probably better left that way.

HTH,
