How do I call a method in an owning object in c++? -

what syntax calling method in owning object owned object in c++?

parent class:

class parent { private:     child child;  public:     parent()     {         addchild(child);     }      void methodtobecalled(int someargument)     {      } }; 

child class:

class child { private:     void myvoid()     {         //call parent method somehow     }  public:     child()     {      } }; 

i tried make question simple , generic possible (to of benefit many possible). let me know if can make clearer.

thank you!

here's example. had modify code bit compile:

class component {};  class parent;  class child   : public component { private:     inline void myvoid();     parent &parent_ref;  public:     child(parent &pr) : parent_ref{pr} {} };  class parent   : public component { private:     child child;  public:     parent() : child{*this}     {         // addchildcomponent(child);     }      void methodtobecalled(int someargument)     {      } };  inline void child::myvoid() {     parent_ref.methodtobecalled(1); }
