Write a C++ class definition for an abstract data type called Graph that models an undirected graph. Vertices are labeled by number from 0 to n-1 where n is the number of vertices in the graph. Implement the following public member functions. • Graph(char *fileName): A constructor that creates the graph using the file passed into the function. o The format of the file is described later in the document. • ~Graph(): An appropriate destructor. • void display() const: Displays the graph's adjacency matrix to the screen using this format (see examples later): o Single space between digits. o First row (top) and first column (left) is vertex 0, second row and column is vertex 1, ..., last row (bottom) and last column (right) is vertex n – 1. • void displayDFS(int vertex) const: Displays the result of a depth first search starting at the provided vertex. o When you have a choice between selecting two vertices, pick the vertex with the lower number. • void displayBFS(int vertex) const: Displays the result of a breadth first search starting at the provided vertex. o When you have a choice between selecting two vertices, pick the vertex with the lower number. • bool isBipartite() const: Returns true if the graph is bipartite and false otherwise.
