Question

I am trying to allocate memory for an array of unknown size that is a datamember of a class.
The datamember is:

PassengerCompartment** pass_comp;

In the copy constructor of the class (Plane) that I want to allocate the array, I have this:
(“given” is a const Plane&)

pass_comp = new PassengerCompartment*[given.NOofAlloc_PasCom];
for (int i=0; i < NOofAlloc_PasCom; i++)
{
     pass_comp = new PassengerCompartment( given.(*pass_comp[i]) );
}

And I am getting this compiler error:

error: expected unqualified-id before ‘(’ token

at this line:

pass_comp = new PassengerCompartment( given.(*pass_comp[i]) );

( the “(” that is mentioned, is the 1st one, after PassengerCompartment)

What have I done wrong?

Thank you for your time!

Answer 1

It is surely not the first bracket, but the second, as given.(*pass_comp[i]) is not valid syntax. Maybe you meant *given.pass_comp[i] (which dereferences given.pass_comp[i])?

Oh, and you probably also want pass_comp[i] instead of pass_comp before the assignment operator.
