Need help in assigning char values to a deque...

I am having some trouble in assigning and printing values from a deque list (if that is the correct way of saying it).
Here's what the program should be doing; it reads a text file with a bunch of words in it, the first word being "Aarhus". It then stores all these values in elements of a deque container named d1. Last, it calls the first element and prints it to the console screen.
Here is the problem I am encountering. Although the whole program compiles correctly, all it displays as the first element is "A" when it should actually be "Aarhus". It would be nice if someone was to help in explaining why this is happenning or other alternatives. Below is the source code to my program:
Language: C++
-Thanks in Advance
That's because deque<char> holds single characters. You might want to change that to deque<std::string> or deque<char*>, although I'm not sure if char* are going to work.

Thanks guys! I figured it out!
Like deathcrush said, all I had to do was declare deque as:
deque<std::string> d1;
I also had to take the * off of input_line in the push_back() call.
