do I need to specify an = operator for this

[Gernot Frisch]

class A
{
struct DATA
{
std::vector<std::string> descriptions, units;
std::vector<double> values;
std::string type, name;
} elalin;
}

Do I need to explicitly write an = operator for 'A' and/or for 'DATA'
?
The operator should call the '=' operator for each member.

Thank you,

No.

Yes, it should.

If this is all your op= needs to do, then no, yo udon't need
to write one yourself. The compiler generated one will do
exactly that:
call op= for the base classes (if they exists)
call op= for all members
