I have a very basic problem with OOP. I have two classes and i want to access a variable in one class which is defined in the other class.

header.h

class1
{
  String a_string;
};

class2
{
 ..
};

class1.cpp

#include "header.h"

class1::class1()
{
  a_string = "TEST";
}

class2.cpp

#include "header.h"

class2::class2()
{
  PromptOK(a_string);
}

How can i use the value of a_string in class2 which is defined in class1?

It's surely very basic noob stuff, but i didn' get it after reading different tutorials.

Hi,

you have to define an object of class1 somewhere, maybe with global scope,

class1 a;

and then use it, for example a.a_string in class2.
