Dans le code suivant, quels sont les bons commentaires ? <First>, <Second>, etc. ne font pas partie du code et ne servent qu'à identifier les commentaires pour cette question.

#include "user-id.h"

#include <iostream>

#include <regex>

#include <string>

#include <array>

// <First> Version 1.0 - Initial implementation by Hoang

// <Second> The pattern used here is specifically designed to match the structure of a valid email address according to the standards defined by the Internet Engineering Task Force (IETF), with the pattern accounting for a combination of alphanumeric characters, dots, underscores, percent signs, plus signs, and hyphens before the '@' symbol, followed by a domain name, and ending with a period and a top-level domain of at least two characters in length. This ensures that only valid email addresses in this format will be accepted.

// <Third> WARNING: This method does not check if the domain is reachable; it only checks the format.


bool isValidEmail(const std::string& email) {

// <Fourth> This regex matches an email address that can contain ". _ % + -"

// Other symbols are not allowed.

std::regex email_regex(R"([a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA0-9]{2,})");

// <Fifth> Returns true if the email address matches the regex

return std::regex_match(email, email_regex);

}

// <Sixth> Using array instead of vector since the number of IDs is fixed.

array<int, NUMBER_OF_IDS> createUserIds() {

std::array<int, NUMBER_OF_IDS> userIds;

// <Seventh> Inputs for test purposes

// for (int i = 0; i < NUMBER_OF_IDS; ++i) {

// userIds[i] = i + 1;

//}

// <Eighth> TODO: Finish the implementation with the list of userIds from HR.

// <Ninth> for (int i = 0; i < NUMBER_OF_IDS; ++i) {

// userIds[i] *= 2;

//}

return userIds;

}
