C program to implement Breadth First Search(BFS).Breadth First Search is an algorithm used to search a Tree or Graph.BFS search starts from root node then traverses into next level of graph or tree, if item found it stops other wise it continues with other nodes in the same level before moving on to the next level. The algorithm starts at the root node (selecting some arbitrary node as the root node in the … Determine the degree of all vertices. Adjacency: A vertex is said to be adjacent to another vertex if there is an edge connecting them.Vertices 2 and 3 are not adjacent because there is no edge between them. C.

This C program generates graph using Adjacency Matrix Method. struct Graph* graph = (struct Graph*)malloc(sizeof(struct Graph)); // initialize head pointer for all vertices. Related post Scatter Plots in C++. C++ Server Side Programming Programming The adjacency list representation of a graph is linked list representation. C/C++ Program for Greedy Algorithms | Set 6 (Prim’s MST for Adjacency List Representation) But any software program is considered in written is simple and understandable manner. In adjacency list representation of the graph, each vertex in the graph is associated with the collection of its neighboring vertices or edges i.e every vertex stores a list of adjacent vertices. 2 -> 1 (4) 2 -> 0 (5) For each edge {a, b}, check if a is connected to b or not. In this tutorial we will discuss about Breadth First Search or BFS program in C with algorithm and an example. edge with minimum weight). This C program generates graph using Adjacency Matrix Method. In this representation we have an array of lists The array size is V. Add the ones which aren't in the visited list to the back of the queue.
