Include code for Graph.h and Graph.cpp

Write a C++ or Java class definition for an abstract data type called Graph that models an undirected graph. Implement the following public member functions: A constructor that creates an empty graph An appropriate destructor. No need if you use Java. void load (char *filename): Creates the graph using the file passed into the function. The format of the file is described later. You may assume load is only called once for a graph. You may modify the argument type of this function if you use Java. void display ():Displays the graph's adjacency matrix to the screen. void displayDFS (int vertex): Displays the result of a depth first search starting 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 first search starting at the provided vertex. When you have a choice between selecting two vertices, pick the vertex with the lower number You are permitted to add extra member functions you feel are helpful. DFS must be implemented using recursion. You can use "queue" in STL in the implementation of BFS Other forms of using STL are not permitted Additional requirements and reminders: Loops are allowed but multiple edges are not allowed. Vertices are labeled numerically from 0 to n-1 where n is the number of vertices in the graph If using C++, name your files Graph.h, Graph.cpp and HW4.cpp. If using Java, name your files Graph.java and HW4.java. Input File Format The function load is responsible for reading in a file corresponding to a graph. The format is as follows: The first line contains a single integer indicating how many vertices are present in the graph. You may make no assumptions on how many vertices in the graph - this means that your constructor will have to use dynamic allocation. All remaining lines contain two integers that indicate an edge connects the two vertices. You can assume that the file exists and is well formed. grapho - Notepa File Edit Format 7 1 2 4 1 5 2 6 3 0 2 1 3 3 5 4 5 6 4 Output: graph0.txt: Adjacency Matrix 001100 0 001 11 0 0 11 0 00 1 1 010 00 11 000 11 0 0 DFS at vertex 0:0 21 3 54 6 BFS at vertex 0:0 23 1 5 6 4
