C++ STL...what are these containers?

[venkatacplpl]

Hi All,

I have introductory knowledge in STL and I am aware of stack ,quee,deck,set,map,vector,list...etc.

When I was going through one book I have come across below.

ArrayStack 
ArrayDeque
DualArrayDeque 
RootishArrayStack

Are they also some type of STL containers,if yes then how they will differ from their counterparts?

Thanks in advance

It is another bunch of data structures. They lack generality and are effective only in special cases, so this is probably why they were not included in standard library.

You can easily google information about each of it in Google.
