Lab #12
Linked lists are cool data structures that offer several significant benefits to arrays. Since they grow as
they’re needed and don’t need to be allocated ahead of time, they’re really efficient in size and speed of
creating and adding items to it. However, since you have to iterate through them from the start to get
any data inside, they are slower to search through.
In lecture, you have been learning how to create one from scratch. This lab will introduce you to the
Standard Template Library’s (STL) list class, which implements the linked list for you.
STL Containers
You have learned about vectors and maps in the past. These are two of the container classes available to
you built into C++. More types are deques (doubly-ended queues, or basically a dynamic array), lists (a
doubly-ended linked list), and a forward_list (singly-ended linked list). Just like with vectors and maps,
lists have many of the same function names that the previous containers have:
begin()
returns the pointer to the beginning of the container
clear()
empties a container
empty()
returns a Boolean if the container is empty
end()
returns the pointer past the end of the container
erase()
removes an element at a given position (passed in by an iterator)
pop_back()
removes/pops an element from the back of the container
pop_front()
removes/pops an element from the front of the container
push_back()
inserts/pushes an element into the back of the container
push_front() inserts/pushes an element into the front of the container
size()
returns an integer of the number of elements in the container
and so on. To get the functionality, make sure you #include at the beginning.
Iterators also work the same:
vector::iterator
map::iterator
list::iterator
Strings also are containers of characters. They can be used exactly like the types above, and they also
include built-in iterators.
What You Will Do
This program should create linked lists from strings, and then remove all of the vowels.
1) Create the file Lab12.cpp.
2) Write a function called fillList that takes parameters for a list and the string to add. The function
should iterate through the string and add each to the list. (So a string “ABC” should be inserted
into a list which will consist of elements [A]->[B]->[C]). Test this function before continuing.
3) Write a function called printList which takes in a list and an ostream (output stream). It should
iterate through a list and print out each element, showing the order they are connected. (From
step 2 above, it should print out like “[A] -> [B] -> [C] -> 0”, where 0 is the NULL
pointer at the end.) Test this function before continuing.
4) Write a function called removeCharacter that takes parameters for the list and a character to
move. It should iterate through the list, moving each instance of the character. Think about what
happens when you remove characters in a list, and what different types of conditions might
occur after doing this. Test this function before continuing.

5) In main, read in input.txt, one line at a time. It should stop when it gets to the line “END”. Call
fillList to fill the list with the line from the file. After that, make calls to removeCharacter to
remove all of the vowels. Then, call printList to print it out to a file called output.txt.
If it helps, draw out some sample lists, and as you trace through your code, think through what the lists
look like at any given time. As you step through your program, does your list look like you’re expecting it
to?
Grading and Turning In
Turn in your program before the end of the lab. Upload only Lab12.cpp unzipped. Grading will be
performed using an automated grading program with a different input file (still input.txt) and will be
compared to an output file (output.txt). The lab instructor will still manually look at your code for the
other grading criteria (functional composition, style, etc.)
