Thread: Where do I put my curly brackets for array

Code:

#include <stdio.h>


int main()
{
    int i = 0;
    
    int array[3][2][4] = {
            {{ 1,  2,  3,  4}, { 5,  6,  7,  8}}, 
            {{ 9, 10, 11, 12}, {13, 14, 15, 16}}, 
            {{17, 18, 19, 20}, {21, 22, 23, 24}} 
         };
   
    return 0;
}

Note that the definition for the array has changed - those commas shouldn't be in there!

I'm pretty sure that technically you don't need them, but should, and will get a warning without them:

Code:

a.c: In function ‘main’:
a.c:8:26: warning: missing braces around initializer [-Wmissing-braces]
    8 |     int array[3][2][4] = {
      |                          ^
    9 |              1,  2,  3,  4,  5,  6,  7,  8,
      |              {{           }  {            }}
   10 |              9, 10, 11, 12, 13, 14, 15, 16,
      |              {{           } {             }}
   11 |             17, 18, 19, 20, 21, 22, 23, 24
      |             {{            } {
   12 |          };
      |          }}
