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

[UG]

Anybody know how to do that?

 

[monical]

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

 

[Basking]

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.

Basking got caught by the TGML processor which wiped out his '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, &quot;%d %d&quot;, &arr[0], &arr[1])!=NUM_COLS) {
fprintf(stderr,&quot;Bad file\n&quot;
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.
