Question

I have a class that contains objects of two other classes. I need one of the classes to be able to get data from the other one. Here’s an example.

class Nom{ /*says what we're eating*/ };
class Chew{ /*stuff that needs to know about what we are eating from nom*/ };

class BigBurrito 
{
   Nom n;
   Chew c;
};

Answer 1

How about passing a pointer to the instance of Nom into Chew? Along these lines:

class Nom {};

class Chew
{
private:
    Nom *m_nom;
public:
    Chew(Nom *nom)
    : m_nom(nom)
    {}
};

class BigBurrito
{
private:
    Nom m_nom;
    Chew m_chew;
public:
    BigBurrito()
    : m_chew(&m_nom)
    {}
};
