Struct array and class functions to work with the array

Using Arduino Programming Questions
#1

Hi guys,

what i’m trying to do is:

I have a struct defined in this way:

struct menuItem{
short parent_id;
String title;
char* function;
}

Then i want to load items into the menu as so:

menuItem items = {{-1, “Home”, “showMenuHome”},{0, “Target points”, “showMenuTargetPoints”},{1, “New target point”, “editTP”}};

then i need a class where to define some functions… one of them should be:

void showTitles()
{
for(int i=0;i< sizeof items/sizeof items[0];i++)
Serial.println(items*.title);*
}
please help me out to do this…

#2 
struct menuItem
{
  short parent_id;
  String title;
  char* function;
};

menuItem items[] =
{
  { -1, "Home", "showMenuHome"},
  {0, "Target points", "showMenuTargetPoints"},
  {1, "New target point", "editTP"}
};

void setup()
{
  Serial.begin(115200);
  showTitles();
}

void loop()
{
}

void showTitles()
{
  for (int i = 0; i < sizeof items / sizeof items[0]; i++)
    Serial.println(items[i].title);
}

Yes but what I am trying to do is to have showTitles inside a class... would that be possible?

Absolutely, but your above code does not even try.

#5

Create a method in the class called 'showTitles'. Pass it a pointer or reference to an object whose class inherits from the 'Print' class. 'Serial' is one such object.

#6

please can you show me some demo code for that? i've been trying for 2 days now to make it work and i can't seem to find the right way to do it...

#7 
class myClass {
  private:
    uint8_t privateVariable;

  public:
    myClass (uint8_t p) : privateVariable(p) {}
    void printPrivateVariable(Print *printPtr);
};

void myClass::printPrivateVariable(Print *printPtr) {
  printPtr->print(privateVariable);
}

myClass myObject(4);

void setup() {
  Serial.begin(115200);
  Serial.println("Starting");
  myObject.printPrivateVariable(&Serial);
  Serial.println();
}

void loop()
