What are some practical examples of graph theory in C++?

Graph theory has many applications in C++. For instance, you can use it for network routing, social network analysis, and even in game development.

Can you explain how Dijkstra's algorithm works in C++?

Sure! Dijkstra's algorithm finds the shortest path from a source node to all other nodes in a graph. It uses a priority queue to explore the nearest unvisited node.

Could you provide a simple C++ code example for Dijkstra's algorithm?

Absolutely! Here's a basic implementation:

#include <iostream>
#include <vector>
#include <queue>
#include <climits>

using namespace std;

void dijkstra(int graph[][V], int src) {
    // Implementation here
}

This sets up the structure; let me know if you want the full code!

What are some other algorithms related to graph theory?

Other important algorithms include Prim's algorithm for minimum spanning trees, Bellman-Ford for shortest paths with negative weights, and Floyd-Warshall for all-pairs shortest paths.
