What is wrong with the following overloaded extraction operator declaration? istream& operator >>(istream& in, const myClass &object);

c. Object should not be a const parameter

a. You cannot put the & on the return type

b. Object should not be a pass by reference parameter

As defined in the text, the pointer variable head

b. is the first node in the list.

a. points to the first node in the list.

c. while(iter!=NULL) iter=iter->link

a. for(iter=NULL; iter != NULL; iter=iter->link)

b. for( iter=head; iter != NULL; iter=iter->link)
