How do I use public member variable outside class?

class A {
   public:
     int VARIABLE = 0;
};

How do I use the public variable inside the function of another class? In Java a public variable can be accessed by using the class name and the dot-operator. Is there something similar in C++?

I think you are referring to static members. In C++ it is done as:

// A.h
class A {
   public:
     static int VARIABLE = 0;
};


// B.h
#include "A.h"

class B {
  public:
    void foo() {
      A::VARIABLE = 5; // < here
    }
};

To summarize comments, the operator you are looking for is the Scope Resolution Operator:
