Can anyone clear this up for me?

Question

This is a pre-test study question for an upcoming test that deals with pointer variables.

Know whether or not a name is associated with the pointer data type in C++.

I don't quite understand what this is referring to...i mean every pointer has to have a variable name..(ex int *varname), but is that what this question is to referring to?

Answer 1

Not necessarily.

You can have a pointer to a pointer.

char **pp;

*p points to an unnamed pointer.

In c, pointer to a pointer is a required construct, as the ref parameter (&) does not exist.

HTH-

Answer 2

hope this helps
