I've recently been trying to get to grips with c++. I wrote the following
small programme to implement a list template. However, it does not behave as
I would have expected. If I define a list of chars or ints in main then all is
ok. But defining the list to be of type char* does not work. If I insert a
string item by typing 
   i aaa
then insert another string by typing
   i bbb
then type 
   d
to display the contents of the list, it prints out
   bbb bbb
If I then type
   s ccc
and then
   d
then what is printed out is 
   ccc ccc ccc
It seems that by reading in a string to the local char array item in main
causes the value of each element in list to be changed to the value of the
newly read in string. Could someone please put me out of my misery explain
what is going on.

Thanks in advance.

PS. I am using gcc version 2.2.2
