No. It is specified in the definition of the copy constructor itself. It should generate an error if a programmer specifies a copy constructor with a first argument that is an object and not a reference.

Agreed- Question more clearely is,weather we can pass by value rather than reference in a copy constructor. No we can not pass data by value in a copy constructor.Since by its defination it must except a reference to copy both the locations byte by byte.
