Suppose the base class and the derived class each have a member function with the same signature. When you have a pointer to a base class object and call a function member through the pointer, discuss what determines which function is actually called—the base class member function or the derived-class function.

C++ Write a public member function incrementNodes for a BinaryTree class that will add 1 to each item in the binary tree. If this function calls any other function, you must write the code for that function as well. Note that the class BinaryTree has a private member variable root which is a Node pointer.

a) Write the member function void deleteNode() that will delete
the first node from the linked list.
b) Modify the LList to create a data member Node *cur that
points to the current node. Write the following member
functions:
• void forward() that moves the cur pointer to the next
node.
• void backward() that moves the cur pointer to the previous
node.
