C++ Adding Linked Lists

[ravana]

Ok I have written a program for class in C++ to add two linked lists overloading the + & += operatorss.

But the method that was explained to me was such that when I add two lists
for example
List1 and List2, results in List1+=List2 & List3=List1+List2

What happens in these cases is that the original lists get destroyed(as in the original lists are empty).

It is not a requirement for the assignment that the lists not be destroyed, I was just curious so I did a little search on the net and I did not find anything relevant. I was just wondering if anyone on here knew anything how to do it.

Thanks in advance.

Ravana.

Can't you just change the tail pointer of list1 to be the head pointer of list 2 and make the head pointer of list 3 the same as the head pointer of list 1?

I assume that is what you want.
