Attached Files: graph1txt (61 B) D graph2.txt (45 B) Due 4/18 before the start of class Attach the source and header file of the graph class in addition to the driver to test the functionality. Create a simple graph class. The graph class should have the following items . an adjacency list or matrix to hold the graph data variables to hold the current size and max size of the graph . default constructor o create empty adjacency list/matrix max size = 10 . overloaded constructor o create empty adjacency list/matrix omax size -int parameter o check if current size is zero o read a formatted file and fill adjacency list/matrix .isEmpty createGraph o The first line in the file contains a number that indicates the number of vertices (n) The vertices are labeled as 1, 2, 3,-- , n-1 Each subsequent line describes the edges from each vertex (see sample file) . dis-depth first search isConnected To determine if a graph is connected, execute a depth first search and mark which nodes were visited. If all nodes are not visited with a dfs, the graph is not connected. Write a driver program to test the class
