Does `Node` have a constructor? If it does there is no difference. – drescherjm Aug 18 '20 at 14:07

yes, it has default and parameterized constructor. – Sakshi Singhal Aug 18 '20 at 14:09

The constructor will be called in either form. – drescherjm Aug 18 '20 at 14:09

Only default will be called.. Then why do we have two syntax for the same thing? – Sakshi Singhal Aug 18 '20 at 14:10

Actually there are more.. `TreeNode* n = new Node{};` – drescherjm Aug 18 '20 at 14:14
