nested class access control in C++
I'm a little confused as to what access a nested class has to the members of an enclosing class. What is the relationship it shares with the outer class?

The nested class does not have any special access to the enclosing class that would not be available to any other class - it can see public members, etc. The nesting only provides a useful scoping mechanism for nested class, but doesn't change its behavior or capabilities.

What about typenames such as vector>int<::iterator, can the iterator class use typename int to type objects inside it's class? I revered the >< because it hides them. – rubixibuc Apr 29 '11 at 03:57

In the general case, no, the nested class wouldn't have special information. In the specific case of vector's iterator class, that class is actually a class template instance that takes the same type parameter as the container class. It's also the case, though, that vector has a value_type typedef of it's type parameter, and that's often used in generic programming. – jwismar Apr 29 '11 at 05:17

@rubixibuc: To format code, put it in backticks: `\`vector
::iterator\`` – MSalters Apr 29 '11 at 07:36
