“Generic” iterator in c++

Question

I have:

void add_all_msgs(std::deque::iterator &iter);

How can I make that function \"generic\", so it can take any kind

Answer 1

template 
void add_all_messages(Iterator first, Iterator last)

usage :

vector v;
add_all_messages(v.begin(), v.end());

You need to specify the end, otherwise you won't know when to stop! It also gives you the flexibility of adding only a subrange of a container.
