Hi folks,

one question:

I try to create a list of lists, using

std::list<std::list> testlist;

but BCC 6 complains:

cannot generate template-specialization from __STL::list<_Tp,_Alloc>

How ist it done coreectly? My knowledge of C++ is still growing...

You want to create a list of lists of WHAT? For example,
a list of lists of integers is created this way:

std::list<std::list<int> > listoflistsofints;

'std::list' requires a template argument.
The second one doesn't have one.

std::list<std::list<type> > a_list_of_lists;
