Creating Your First Graph

1. In your main.cpp import Graaf:

#include <graaflib/graph.h>

2. Define a directed graph g

graaf::directed_graph<const char, int> g;

3. Add vertices to the graph:

const auto a = g.add_vertex('a');
const auto b = g.add_vertex('b');
const auto c = g.add_vertex('c');

4. Connect the vertices with edges:

g.add_edge(a, b, 1);
g.add_edge(a, c, 1);

5. Putting it all together:

#include <graaflib/graph.h>

int main()
{
    graaf::directed_graph<const char, int> g;

    const auto a = g.add_vertex('a');
    const auto b = g.add_vertex('b');
    const auto c = g.add_vertex('c');

    g.add_edge(a, b, 1);
    g.add_edge(a, c, 1);

    return 0;
}

Congratulations! You just created the following graph 🎉
