ECE250: Lab Project 1

1. Project Description
The goal of this project is to write a C++ program that manages a playlist of songs. The
program allows the user to add songs to this list (at the end of the list), and select a song
to be played. We will use the vector template class of the C++ Standard Template
Library (STL) to store the entries of the playlist. Each entry will contain the name of the
song and the corresponding artist.
For this exercise, we ask you to use the object-oriented paradigm to implement your
solution. You will create a design in which the playlist and the entries in the list are
represented by classes that: (i) store their properties (data members) and (ii) provide
services (function members).
2. The Vector Template Class
The vector template class is similar to a C++ array, with the added feature of
performing bounds checking and the ability to expand. Since vector is a C++ class
template, you can use this class to represent vectors of different data types (e.g., int,
double) or a vector of your own data type.
3. Program Design
Write a short description of your design. You will submit this document along with your
C++ solution files for marking. This document must include your design decisions.
Please refer to the course website for “Programming Guidelines” and the expected
content for your design document.
4. Input/Output Requirements
Write a test program named playlisttest.cpp that reads commands from standard
input and writes the output to standard output. This program will respond to the
commands described in this section.
Command Parameters Description Output
i s;a Adds a song (with the title s and
the artist a) at the end of the
playlist if the song is not already
in the list
success
or
can not insert s;a
p n Plays the song at position n
played n s;a
or
could not play n
e n Erases the song at position n
success
or
could not erase n

• Test Files
The course website contains example input files with the corresponding output. The files
are named test01.in, test02.in and so on with their corresponding output files named
test01.out, test02.out and so on.
5. How to Submit Your Program
Once you have completed your solution and tested it comprehensively in your computer
or on the lab computers, you have to transfer your files to the eceUbuntu server and test
there since the automated testing is done using this environment. Once you finish
testing in the eceUbuntu server, you will create a compressed file (tar.gz) that should
contain:
• A document (maximum two pages) describing your design. This document must
be typed for marking and should be submitted in PDF (e.g., design.pdf).
• A test program (playlisttest.cpp) containing your main() function
• Required header files and classes (ending in .h .cpp)
• If your implementation requires more than one file (playlisttest.cpp) listed in g++
line for compilation, you will need to add to the design document the complete
g++ command line, or provide a make file (named Makefile).
The name of your compressed file should be xxxxxxxx_pn.tar.gz, where xxxxxxxx is
your UW user id (e.g., jsmith) and n is the project number that is 1 (one) for this
submission.
