C++same class as member in class

Question

I have a class that should have a class of the same type as its member.

My declaration is the following:

class clsNode
{
private:
     clsNode m_Moth         


        

Answer 1

You can't have a member of the same type inside the class. The compiler tries to calculate the size of the object and sort of "gets into a loop." You can get around that by using indirection. For example, you can store the pointer to the mother node.

class clsNode
{
private:
     clsNode* m_Mother;
public:
     void setMother(const clsNode &uNode, int index);
};
