C++ programming coding

Assume that we want to create a linked list structure to items.  We are given 

struct item

{

  string data;  item *next;

  item(string x, item* t)

    { 

      data = x; next = t;

    } 

};

In our implementations we used first and last pointers to keep first items and last item of linked list. Once we add new item, a new structure is created and add as last item. 

In this quiz, assume that we have only first pointer, and do not have last pointer. Complete the following function to add an item to at the beginning (front) of Linked Listed using only "first" pointer.  Just submit function implementation, not the whole program.

bool Bag::insertFront(string str)
{

}
