Description
- This is an individual assignment. Please do not collaborate
- If you think that this document does not clearly describes the assignment, ask questions before its too late.
This assignment is about using C++ STL, exception handling and/or creating Class templates.
- Your program reads two files:
- txt
- txt
- According to content in data.txt, the program utilizes necessary STL classes and/or user-created classes for a catalog representation.
- Your program creates a log file(output.txt) for certain steps of operations performed on catalog. txt
- This file holds information about a catalog. A catalog can be one of the following:
- Book catalog
- Music catalog
- Movie catalog
- The type of the catalog is specified in the first line of data.txt
Book Catalog
- Each line in a book catalog keeps information about a book.
- Format:
<title> <authors> <year> <tags>
- Example: Contents of data.txt for a book catalog
- book
- “Hilbert Spaces With Applications” “Lokenath Debnathl, Piotr Mikusinski” “2005” “Mathematics,
,→ Set Theory”
- “The Neolithic Revolution in the Near East: Transforming the Human Landscape” “Alan H. Simmons”
,→ “2011” “Social Science, Anthropology, Cultural, General, Archaeology”
- “Learning Flask Framework” “Matt Copperwaite, Charles Leifer” “2015” “Computers, Programming
,→ Languages, Python, Internet, Application Development, Web, Web Programming”
- “Graphics Gems V” “Alan W. Paeth” “1995” “”
Music Catalog
- Each line in a music catalog keeps information about a music album.
- Format:
<title> <artists> <year> <genre>
- Example: Contents of data.txt for a music catalog
- music
- “Professor Satchafunkilus and the Musterion of Rock” “Joe Satriani” “2008” “Guitar Virtuoso”
- “Physical Graffiti” “Led Zeppelin” “1975” “Rock”
- “Witchdoctor’s Son” “Okay Temiz, Johnny Dyani” “2017” “Jazz, Fusion”
- “Return Of The Mother Head’s Family Reunion” “Richie Kotzen” “2007” “Rock, Guitar Virtuoso”
Movie Catalog
- Each line in a movie catalog keeps information about a movie.
- Format:
<title> <director> <year> <genre> <starring>
- Example: Contents of data.txt for a movie catalog
- movie
- “The Lord of the Rings: The Fellowship of the Ring” “Peter Jackson” “2001” “Adventure, Drama,
,→ Fantasy” “Elijah Wood, Ian McKellen, Orlando Bloom”
- “Twelve Monkeys” “Terry Gilliam” “1995” “Mystery, Sci-Fi, Thriller” ” Bruce Willis, Madeleine
,→ Stowe, Brad Pitt”
- “Perfume: The Story of a Murderer” ” Tom Tykwer” “2006” “Crime, Drama, Fantasy” “Ben Whishaw,
,→ Dustin Hoffman, Alan Rickman”
- “Cold Mountain” “Anthony Minghella” “2003” “Adventure, Drama, History” ” Jude Law, Nicole
,→ Kidman, Renee Zellweger” commands.txt
This file includes several commands which work on the catalog information you read from data.txt. Each line is a command. The following should be recognized:
- There are two commands.
search <string> in <field> sort <field> search command
- Format: search <string> in <field>
- Output:
This command returns a list of matched(partially or fully) entries (one entry in a line). Search should be limited to the field specified. Not found returns no line.
- Example:
search “Joe” in “artists” This returns the following line:
“Professor Satchafunkilus and the Musterion of Rock” “Joe Satriani” “2008” “Guitar Virtuoso” sort command
- Format: sort <field>
- Output:
This command returns a list of sorted entries (ascending order)
- Example:
sort “title”
This returns the following lines: 1 “Cold Mountain” “Anthony Minghella” “2003” “Adventure, Drama, History” ” Jude Law, Nicole
,→ Kidman, Renee Zellweger”
- “Perfume: The Story of a Murderer” ” Tom Tykwer” “2006” “Crime, Drama, Fantasy” “Ben Whishaw,
,→ Dustin Hoffman, Alan Rickman”
- “The Lord of the Rings: The Fellowship of the Ring” “Peter Jackson” “2001” “Adventure, Drama,
,→ Fantasy” “Elijah Wood, Ian McKellen, Orlando Bloom”
- “Twelve Monkeys” “Terry Gilliam” “1995” “Mystery, Sci-Fi, Thriller” ” Bruce Willis, Madeleine
,→ Stowe, Brad Pitt” output.txt
This file keeps the log of the operations. The following events should be recorded in the specified format:
- catalog read
- output of commands catalog read
- First specify the type of the catalog.
- At the end, state the number of unique entries.
Catalog Read: music 4 unique entries output of commands
- State the command.
- Append its output.
search “Joe” in “artists”
“Professor Satchafunkilus and the Musterion of Rock” “Joe Satriani” “2008” “Guitar Virtuoso”
Exceptions
- Your program should catch certain exceptions and create log entries for them.
- You need to catch the following exceptions:
Missing field exception
- If any of the field in any entries is missing your program should omit that line and create an exception record in the log file.
Exception: missing field
Duplicate entry exception
- If the first field of any entries fully match, your program should create an exception for each repetition and log these instances in the log file.
Exception: duplicate entry
Wrong command exception
- If the command is not in the expected format(unrecognized field name, extra information etc…), log this instance as an exception. Exception: command is wrong
A full example.
- Suppose we are given the following data.txt file and commands.txt file:
- txt
- movie
- “The Lord of the Rings: The Fellowship of the Ring” “Peter Jackson” “2001” “Adventure, Drama,
,→ Fantasy” “Elijah Wood, Ian McKellen, Orlando Bloom”
- “Twelve Monkeys” “Terry Gilliam” “1995” “Mystery, Sci-Fi, Thriller” ” Bruce Willis, Madeleine
,→ Stowe, Brad Pitt”
- “Twelve Monkeys” “” “” “Sci-Fi, Thriller” ” Bruce Willis, Madeleine Stowe, Brad Pitt” 5 “Perfume: The Story of a Murderer” ” Tom Tykwer” “2006” “Crime, Drama, Fantasy” “Ben Whishaw,
,→ Dustin Hoffman, Alan Rickman”
- “Twelve Monkeys” “” “” “Mystery, Sci-Fi, Thriller” ” Bruce Willis, Madeleine Stowe, Brad Pitt”
- “Cold Mountain” “Anthony Minghella” “2003” “Adventure, Drama, History”
- commands.txt
- search “Monkeys” in “title”
- search “Spice” in “type”
- sort “year”
- The first line is movie. This means your application will going to run in movie organiser mode.
- Following is the log file for this example:
- txt 1 Catalog Read: movie
- Exception: duplicate entry
- “Twelve Monkeys” “” “” “Sci-Fi, Thriller” ” Bruce Willis, Madeleine Stowe, Brad Pitt”
- Exception: duplicate entry
- “Twelve Monkeys” “” “” “Mystery, Sci-Fi, Thriller” ” Bruce Willis, Madeleine Stowe, Brad Pitt”
- Exception: missing field
- “Cold Mountain” “Anthony Minghella” “2003” “Adventure, Drama, History”
- 3 unique entries
- search “Monkeys” in “title”
- “Twelve Monkeys” “Terry Gilliam” “1995” “Mystery, Sci-Fi, Thriller” ” Bruce Willis, Madeleine
,→ Stowe, Brad Pitt”
- Exception: command is wrong
- search “Spice” in “type”
- sort “year”
- “Twelve Monkeys” “Terry Gilliam” “1995” “Mystery, Sci-Fi, Thriller” ” Bruce Willis, Madeleine
,→ Stowe, Brad Pitt”
- “The Lord of the Rings: The Fellowship of the Ring” “Peter Jackson” “2001” “Adventure, Drama,
,→ Fantasy” “Elijah Wood, Ian McKellen, Orlando Bloom”
- “Perfume: The Story of a Murderer” ” Tom Tykwer” “2006” “Crime, Drama, Fantasy” “Ben Whishaw, ,→ Dustin Hoffman, Alan Rickman”
