What are some tricks I can use with macros? [closed]

Answer 1

When i work on huge c/c++ nested structures like the one used for 3GPP RRC/NBAP/RNSAP, i follow this trick to make the code look clean.

struct leve1_1
{
  int data;

  struct level2
  {
    int data;

    struct level3
    {
      int data;
    } level_3_data;

  } level_2_data;

} level_1_data;

level_1_data.data = 100;

#define LEVEL_2 leve1_1_data.level_2_data
LEVEL_2.data = 200;

#define LEVEL_3 LEVEL_2.level_3_data
LEVEL_3.data = 300;

#undef LEVEL_2
#undef LEVEL_3

This will make life easier during maintenance time..also in design time and code will be readable.
