Question

The struct is defined like this:

 struct Edge {
    int weight;
    Vertex* v1;
    Vertex* v2;
  };

I need to do something like

new Edges(v1, v2, v3);

but that could only be done with a “class” and using ctor. How can I create a new element of struct and initialize it at the same time?

Thanks!

You can write a constructor for a struct as well in C++. A C struct is very limited, but in C++ there exists only 2 differences between struct and class.

1. In class all members are by default private, in struct all members are by default public.
2. Inheritance from struct defaults to public while class defaults to private
