"WebDirected Graph Implementation. Following is the C implementation of a directed graph using an adjacency list: As evident from the above code, in a directed graph, we only create an edge from src to dest in the adjacency list. Now, if the graph is undirected, we also need to create an edge from dest to src in the adjacency list, as shown below: 2. " - Graph adjacency list implementation c++
