Exemple

class Enclosing { private: int field; public: class Nested { void function(Enclosing *ptr) { ptr->field = 10; } }; };

Solution

Déclarez la classe imbriquée comme étant amie. class Enclosing { private: int field; public: friend class Nested; class Nested { void function(Enclosing *ptr) { ptr->field = 10; } }; };
