I need to dynamically initialize a fixed number of entries of the form: (start, length) and iterate over them.

Hence, I think a struct makes sense:

struct S {
  s1, l1
, s2, l2
, s3, l3
}

Now I need to initialize the values like this:

S myS = {s1:0, l1:10, s2:(2*s1), ...};

So I somehow would like to reference the prior values to initialize the other members. I haven't found a way to do it. Is this possible at all? Or do I just init the struct empty and then set the entries?

I don't think so.

I recommend using a factory function or ctor.
