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 give me a specific example of a graph algorithm implemented in C++?

Sure! One common example is Dijkstra's algorithm, which finds the shortest path between nodes in a graph. Would you like to see a code snippet?

Yes, please share the code snippet for Dijkstra's algorithm.

Here's a simple implementation of Dijkstra's algorithm in C++:

#include <iostream>
#include <vector>
#include <queue>
#include <climits>
using namespace std;

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

Let me know if you need further explanation!

What are the time complexities of different graph algorithms?

The time complexity varies: Dijkstra's algorithm is O(V^2) with a simple array, but O(E + V log V) with a priority queue. BFS and DFS are O(V + E).
