LuaExample2

-- Kaizer here. I created a phonebook in Lua displaying contact names, with the ability to search for existing contacts, delete contacts, e.t.c.

Contact = {}
Contact.__index = Contact

function Contact.new(name, phone_number, email)
    local self = setmetatable({}, Contact)
    self.name = name
    self.phone_number = phone_number
    self.email = email
    return self
end

function Contact:getName()
    return self.name
end

function Contact:getPhoneNumber()
    return self.phone_number
end

function Contact:getEmail()
    return self.email
end

function Contact:display()
    print(string.format("Name: %s, Phone: %s, Email: %s", self.name, self.phone_number, self.email))
end

Phonebook = {}
Phonebook.__index = Phonebook

function Phonebook.new()
    local self = setmetatable({}, Phonebook)
    self.contacts = {}
    return self
end

function Phonebook:addContact(name, phone_number, email)
    table.insert(self.contacts, Contact.new(name, phone_number, email))
    print(string.format("Contact %s added successfully.", name))
end

function Phonebook:deleteContact(name)
    for i, contact in ipairs(self.contacts) do
        if contact:getName() == name then
            table.remove(self.contacts, i)
            print(string.format("Contact %s deleted successfully.", name))
            return
        end
    end
    print(string.format("Contact %s not found.", name))
end

function Phonebook:searchContact(name)
    for _, contact in ipairs(self.contacts) do
        if contact:getName() == name then
            print("Contact found:")
            contact:display()
            return
        end
    end
    print(string.format("Contact %s not found.", name))
end

function Phonebook:displayContacts()
    if #self.contacts == 0 then
        print("No contacts in the phonebook.")
    else
        print("Contacts in the phonebook:")
        for _, contact in ipairs(self.contacts) do
            contact:display()
        end
    end
end
