Thread: Initialising a 3D array - Segmentation fault

Can anyone tell me where the error is here? I get a Segmentation Fault error upon running the code (it compiles fine). Cheers.

The variable "size" and the constants are all initialised/defined properly.

Code:

   int array[MAX_HOUR - MIN_HOUR + 1][MAX_MINUTE - MIN_MINUTE + 1][size];

   for (i = 0; i <= MAX_HOUR - MIN_HOUR; i++) {
      for (j = 0; j <= MAX_MINUTE - MIN_MINUTE; j++) {
         for (k = 0; k < size; k++) {
            array[i][j][k] = 0;
         }
      }
   }

What do you have for the values of MAX_HOUR, etc. ? Are these defines or what?

3D arrays really eat up a lot of memory fast. May be crashing the stack.

Yeah, they are defines.

#define MAX_HOUR 12
#define MIN_HOUR 6
#define MAX_MINUTE 30
#define MIN_MINUTE 0

size is just an integer variable. By the time this code is run, size = 10.

I'm running your code with no problems - but I had to make size a define or constant - required for my compiler to make static arrays.

Are you getting any warnings? Maybe size is NOT 10 at this point in the program?

You're right, the error occurs because "size" is being accessed. Not because of the code itself. I tried printing the value of size but get the same segmentation error.

I'll investigate further.

Thanks heaps for your help.

You're welcome, and good hunting.

and don't cross-post.
