Need help to write alternative and shorter version of this code.

Good day to everyone,

First of all i would like to thank you everyone in this forum, it is really great and helpful. i,ve got help every time when i needed. THANK YOU to everyone.
okay, so i am writing a code for a menu, and it is working completely fine, nothing wrong with the code. i am beginner and not really smart about this programming, so i just made a flowchart and converted every block of it to appropriate step of the following code. They are working as they should be. but they are very lengthy.
i got a query that there must be a shorter version or some some logical steps to do what following codes are doing. kindly help me with this.
Best Regards.

Just a quick look suggests an array for the booleans, where:

bool menu[9];

where the elements are interpreted as:

boolean_of_menu = menu[0];
boolean_of_select_set_point = menu[1];
boolean_of_dose_timing = menu[2];
boolean_of_dose_interval = menu[3];
boolean_of_pH_lw_up = menu[4];
boolean_of_forced_dose = menu[5];
boolean_of_alarm_deviation = menu[6];
boolean_of_alarm_per_hr = menu[7];
boolean_of_alarm_on_off = menu[8];

Now do your digitalRead() calls, then:

   memset(menu, false, sizeof(menu));     // Sets all members of the array to False

   if ( menu_button_state == LOW && select_button_state == LOW) {
      menu[to_be_print] = true;
   }

Untested, but should be close.

Where you have a series of things and all but one needs to be set false just have a function that turns them all false and then turn one of them to true. The same function can be called for each menu button, That function will, of course, be easiest to implement with an array. Something like

void clearSettings() {
  for (byte n = 0; n < numButtons; n++) {
     menu[n] = false;
  }
}
