A class A declaring another class B as a friend will: a. Have wine and cheese with that other friend. b. Allow class A to access the declared private variables in class B. c. Allow class B to access the declared private variables in class A. d. None of above. In preorder traversal: a. The externals of a subtree are visited first. b. A node is visited after its left subtree and before its right subtree. c. The root is visited first and then the subtrees rooted at its children are traversed recursively. d. All of above.

Write a C++ a class definition for an abstract data type called Graph that models anundirected graph. Some implementation details: Create code for a .cpp file with main function and code for a .h file with classes • Loops are allowed but multiple edges are not allowed.• Vertices are labeled by number from 0 to n-1 where n is the number of vertices in thegraph.Implement the following public member functions.• A constructor that creates an empty graph.• An appropriate destructor.• void load(char *filename): Creates the graph using the file passed into thefunction. The format of the file is described later. You may assume load is only calledonce for a graph. • void display(): Displays the graph's adjacency matrix to the screen.• void displayDFS(int vertex): Displays the result of a depth first searchstarting at the provided vertex. When you have a choice between selecting two vertices,pick the vertex with the lower number.• void displayBFS(int vertex): Displays the result of a breadth…
Given the following specification of a front operation for queue:ItemType Front Function: Returns a copy of the front item on the queue. Precondition: Queue is not empty. Postcondition: Queue is not changed. 1. Write this operation as client code, using operations from the QueType class. (Remember,the client code has no access to the private variables of the class). 2. Write this function as a new member function of the QueType class. help me with complete code
Tree.java: This is a simple binary tree class that should be used to represent the data in your Huffman tree. You only need to implement two of the methods (_printTree and compareTo).
