April 04, 2020 Dynamically init a struct with values calculated from other values in the struct? | ||||

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?
