Question

class Base
{
    private: bool mEnabled;
    public: bool getEnabled() { return mEnabled; }
};

class First : public Base;
{
  // ...
};

class Second : public Base
{
   Second() {
      // I have to check First::mEnabled
   }
};

class Manager
{
    First obj1;
    Second obj2;
};

I have some class manager which handles 2 another classes. And I have to check mEnabled variable in one such object from another. What’s the right way? Would it be right if I’ll make

static bool mEnabled;
static bool getEnabled();

p.s. There would be only 1 objects of this classes.

Answer 1

Instead of static you probably would check for getEnabled in your class manager:

if( obj1.getEnabled() )
{
    Second obj2;
}

The problem is that you want to get access to another class without any relation between them. So a more top-level class needs to create this relation.
