  1. void gpio_set_output( struct MENU_ENTRY *menu_entry )
  2. {
  3.   if( menu_entry->user_data < 10 )
  4.     gpio_digital_outputs[menu_entry->user_data].state = true;
  5.   else
  6.     gpio_digital_outputs[menu_entry->user_data - 10].state = false;
  7.  
  8.   // Display state of the output
  9.   if( gpio_digital_outputs[(menu_entry->user_data < 10 ? menu_entry->user_data : menu_entry->user_data - 10)].state == true )
  10.     menu_edit_output[1].data = (void *) "ON";
  11.   else
  12.     menu_edit_output[1].data = (void *) "OFF";
  13. }

what a piece of code did i wrote now

oh. deer. god.

i placed a ternary operator in array element number

also check this out:

  1.         case MENU_COMMAND:
  2.         {
  3.           // Some hard core C hacking here
  4.           //
  5.           // The code below takes address to a function and type casts it
  6.           // from (void *) to a function which can be invoked
  7.  
  8.           void (*function_ptr)(struct MENU_ENTRY *) = (void (*)(struct MENU_ENTRY *)) menu_current[menu_cursor_position].data;
  9.           (*function_ptr)( &menu_current[menu_cursor_position] );
  10.           break;
  11.         }
