Question

I’m looking for a method for initializing a complex struct which contains vector in a single row.

For example if I have this structure:

struct A{
  double x;
  double y;
};
struct B{
  double z;
  double W;
};
struct C{
  A a;
  B b;
};

I can initialize C in this way: C c = {{0.0,0.1},{1.0,1.1}};

But what If I have to initialize a struct like this?

struct A{
  double x;
  double y;
};
struct B{
  vector<double> values;
};
struct C{
  A a;
  B b;
};

I have to do it in a single row because I want to allow the users of my application to specify in a single field all the initial values. And of course, I would prefer a standard way to do it and not a custom one.

Thanks!

You can initialise C in a very similar way in C++ to in C:

C c = {{0.3, 0.01}, {{14.2, 18.1, 0.0, 3.2}}};
