MHB I have a question on constructor and overload?

[needOfHelpCMath]

Can overload and constructor be in private? for example my overload constructor:

class Node {
      
      private:
             int  Nodedata;
             Node *next;
             Node() {next =  NULL; Nodedata = 0;}
             
             Node(int data = 0, Node *nextNode) { //overloaded constructor
             Nodedata = data;
             next = nextNode;
           }
		   };
     public:
           void insertToFront();
           void insertBack();
           void insertMiddle();

What happens if you try to create an object of the type Node in the main? Or some class other than the Node class.

 

[HallsofIvy]

Setting a function, in an object, "private" means that it can only be seen or used by that object. Setting a constructor "private" means that object can only be constructed by the object itself- which hasn't been constructed yet!

doesn't work ahaha XD but i was just curious if it works

Good that you tried! Now read HallsofIvy's post for why.

Never forget the four key principles of object orientated programming!

Quiz: Which key principle does your question mostly relate to?

hmmm...i think the principle is to understand constructors and class and how they work together?

That's not quite what i was getting at :p :D. But good point nonetheless.

Have you learned about the four principles of OO;

Encapsulation, inheritance, polymorphism, and abstraction?

nope never heard of them and i am taking a class on data structures.
