    Can you have a 2D array of structures?

    I just read that 2D arrays can only be of type char, int, or double.

    I have a structure that has 3 int variables. Is it possible to store this structure in each element of the array?

    Thanks.

    A 2D array of classes is a great deal harder though.

    Yes, though you'll find the syntax has been complicated a bit due to extra levels of membership:
    Code:
    #include <stdio.h>
    
    struct blah {
      int a, b, c;
    };
    
    int main ( void )
    {
      struct blah feh[2][2] = {
        {
          {1,2,3},
          {4,5,6},
        },
        {
          {10,11,12},
          {13,14,15},
        }
      };
      int i, j;
    
      for ( i = 0; i < 2; i++ ) {
        for ( j = 0; j < 2; j++ )
          printf ( "(%d,%d,%d)", feh[i][j].a, feh[i][j].b, feh[i][j].c );
        printf ( "\n" );
      }
    
      return 0;
    }
    My best code is written with the delete key.
