Create object of class inside (same) class

[kyrresc]

Hello,


In C++, is it possible to create an object of a class X inside class X? For example inside a member function.

Here is an object of class X creating another object of class X in a member function

#include <iostream>

class X
{
public:
  X makeAnX();
};

X X::makeAnX()
{
  X aNewX;
  return aNewX;
}

int main()
{
  X firstX;
  std::cout << "Address of first X: " << &firstX << '\n';
  auto another = firstX.makeAnX();
  std::cout << "Address of another X: " << &another << '\n';
}

};
