a data array where each element has two values, not just one?

**HAL** · 08-12-2012

Hi. New here. Not new to C programming but have never gone much deeper than the basics.

I have worked with data arrays for embedded DSP algorithms, and although some of them have been of two or three or more dimensions, up until now all these arrays have had a single data value per element. [i hope i am using the correct terms...

]

Now i am working on an algorithm that seems to need two dimensions and two data values that need to change independently, per element.
I'm not sure how to go about this.

I have looked over the tutorials, but so far i haven't found this subject discussed.
Is this easy to do?
Is this going to be possible with arrays or will i need to move up to pointers?
Is this covered in the tutorials somewhere? If not, please advise. Thanks.

Regards,

Sounds like you're looking for an array of structs.

Code:

#include <stdio.h>

#define XSIZE 10
#define YSIZE 10

struct Element {
    int m;
    int n;
};

int main(void) {
    struct Element a[YSIZE][XSIZE];
    a[0][0].m = 1;
    a[0][0].n = 2;
    printf("%d %d\n", a[0][0].m, a[0][0].n);
    return 0;
}

Hi oogabooga! Thanks for the quick response. This looks like just what i need. Structures - awesome! Thanks for the help!
