How can I implement graphs in C programming?

You can implement graphs in C using adjacency lists or adjacency matrices. Which method would you like to explore?

What's the difference between adjacency lists and matrices?

Adjacency lists use less space for sparse graphs, while matrices are easier for dense graphs. Do you have a specific graph in mind?

I want to create a graph for a social network. What should I consider?

Consider the number of users, connections, and the type of operations you'll perform, like adding or removing users.

Can you show me a simple code example for an adjacency list?

Sure! Here's a basic example:

#include <stdio.h>
#include <stdlib.h>

struct Node {
    int data;
    struct Node* next;
};

struct Graph {
    int numVertices;
    struct Node** adjLists;
};

struct Node* createNode(int);
struct Graph* createGraph(int);
