    Creating Linked List using inheritance or composition?

    I know I can create a stack or queue from my base class of a linked list through composition or inheritance. My question is can I do this the other way around, I know most functions can be done, but I m particularly intrigued by removefromback since both stacks and queues remove from front. Would I have to create this function from scratch or is there a work around using inheritance or composition.

    A linked list is neither a stack nor a queue, and I do not see why a linked list would have a stack or a queue, so this does not make sense to me.

    I know, I'm talking about the use of its functions. A push function from stack could be used for insertatfront for a linked list etc... Am i making sense?

    If you're asking if you can simulate a LL using a stack, the answer would be no (well not easily anyway).

    A LL supports insertion at any point in the list.

    I suppose you could fake random insertion by popping everything off one stack until you reach the insert point, put the new item in, then push everything back again.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
