alias

The ____________________ operator causes a member-wise copy of the member variables of the class.

assignment

assignment

The ____________________ of an array is the address (that is, the memory location) of the first array component.

base address

The ____________________ operator function as a member of a class has only one parameter; as a nonmember of a class, it has two parameters.

parallel
