Need help with a c++ question.

This module includes the definition of a class that manages information about a single reservation at a restaurant for a date/time in February.

Design and code a class named Reservation that can store the following information (for each attribute, chose any type that you think is appropriate--you must be able to justify the decisions you make):

• reservation id: an array of characters
• the name on the reservation
• the email to be used to send a confirmation that the reservation can be honoured or cannot
• the number of people in the party
• the day when the party expects to come (for simplicity, the day is an integer between 1 and 28)
• the hour when the party expects to come (for simplicity, the hour is an integer between 1 and 24)

Public Members

a default constructor

void update(int day, int time): a modifier that receives as parameters a new day and time for the reservation and updates the attributes with received values. Assume the parameters are correct and don't require validation.

Reservation(const std::string& res): A constructor that receives the reservation as a string; this constructor is responsible for extracting information about the reservation from the string and storing the tokens in the instance's attributes. The string will always have the following format:

ID:NAME,EMAIL,PARTY_SIZE,DAY,HOUR 

This constructor should remove all leading and trailing spaces from the beginning and end of any token extracted from the string.

When implementing the constructor, consider this following functions:

• std::string::substr()
• std::string::find()
• std::string::erase()
• std::stoi()

Friend Helpers

• overload the insertion operator to insert the contents of a reservation object into an ostream object:
  • if the hour is between 6AM and 9AM (inclusive), the kitchen serves breakfast:
  • if the hour is between 11AM and 3PM (inclusive), the kitchen serves lunch:
  • if the hour is between 5PM and 9PM (inclusive), the kitchen serves dinner:
  • at any other time the kitchen is closed and only drinks can be served:
  • the ID on the reservation should display on a field of size 10, aligned to the right
  • the name on the reservation should display on a field of size 20, aligned to the right
  • the email on the reservation (including the characters < and >) display on a field of size 20, aligned to the left.
  • this operator should insert the end line character before returning control.
  • if the reservation is for one person, your output should say "person" instead of "people".
