Const& parameter?

Const& parameter?

Const& parameter?

(OP)
Hello,

I am using a class whose constructor takes a parameter as follows:

CODE

Class(const OtherClass& param1)

My code is basically:

CODE

OtherClass oc = new OtherClass();

Class c = new Class(oc);

...which generates errors. How do I properly pass the OtherClass instance to this constructor?

RE: Const& parameter?

The constructor takes a const reference, not a pointer.
C++ != Java

Do this instead:

CODE

OtherClass oc;
Class c( oc );

or if you really want to use pointers for some reason, then do this:

CODE

OtherClass* oc = new OtherClass;
Class* c = new Class( *oc );
but then don't forget to delete those pointers when you don't need them anymore...

CODE

delete oc;
oc = NULL;
delete c;
c = NULL;
