I guess he has a problem because of the object he's using?
If you created it by 
"Classname *myClass = new Classname(.);",
you'll need to call
 myClass->name(),
but if you did not create a pointer to the object like saying
"Classname myClass(.);"
you'll have to say 
myClass.name()
you could also say 
&myClass->name();
as '&' passes the reference to the object.
If you're referencing from inside the object (class member function, 
Classname::function()) you can simply call "name()" or "this->name()")

However, imho this is not the correct list for those things, as you're asking 
about cpp basics?!
