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

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.

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.
