Claudio Montanari - Music Library Service Project

Installation

To install the project import it in a C++ editor (CLion for instance) and set the compiler to c++11.

Features

The Music Library Service prompts the user a menu with the following commands:

• l : List all the files in the list
• e : Ask the user an ID between 0-9 to set as current clip
• c : Ask the user to insert the data that will be used to create a new clip or update an existing one
• y : Copy the current clip into a temporary file named "temp.clip"
• i : Reads the list of commands from the file "input.inp"
• p : Ask the user to insert the new price for the current clip
• s : Save all the clip that are in memory into their file (all such files are places into the "files" directory)
• q : Quit from the system

Notes

The create new clip functionality requires the user to insert the following data (in this order):

• ID : ID of the clip that should be updated or created
• Title : the song title
• Artist : the artist name
• People : a band member (write "quit" to stop adding members)
• Genre : a number between 1-9 for the music genre (it will be mapped according to the following ordered list: POP_MUSIC, FOLK_MUSIC, JAZZ, BLUES, CLASSICAL, COUNTRY_MUSIC, REGGAE, ROCK, OPERA)
• Price : a decimal number for the price

The read from file functionality require that a valid list of commands is inserted in the file "input.inp". In particular, the file should be formatted putting every input in a new line. For instance, the following is a valid input file (what follows the // is just a comment and shouldn't be placed into the input file):

l                       //List all the clips
c                       //Create or update a clip
