Jun 13, 2024 · In C++, graphs are non-linear data structures that are used to represent the relationships between various objects. A graph is defined as a collection of vertices and edges. In this article, we will learn how to implement the graph data structure in C++.

Simply, define a graph as a map between nodes and lists of edges. If you don't need extra data on the edge, a list of end nodes will do just fine. Thus a succinct graph in C++, could be implemented like so: using graph = std::map<int, std::vector<int>>; Or, if you need additional data,

Apr 1, 2025 · This tutorial explains implementation of Graphs in C++. You will also learn about different types, representation, and applications of graphs.

We stay close to the basic definition of a graph - a collection of vertices and edges {V, E}. For simplicity, we use an unlabeled graph as opposed to a labeled one i.e. the vertices are identified by their indices 0,1,2,3. Let's dig into the data structures at play here. struct node* next; . struct Graph{ int numVertices;
