I trying to make a code that gives the user a personal number after they have made an user

Question

Here is my ruby code. When you run it and you press 1 it will ask you for name and birth of date. I want to give the user a personal number after he is finished typing name

Answer 1

I am not sure how you want the numbers generated, but something like this could work.

This will always give you the highest number from your text file, and add 1 to it.

Keep in mind this method will be slow with a rather large amount of employees.

if File.exist?('Capgemini.txt')
    number = File.readlines('Capgemini.txt')
    @number = 1
    number.each do |x|
      customer = x.split(',')
      customer_number = customer[1].gsub('Number: ', '').to_i
      if customer_number >= @number
        @number = customer_number + 1
      end
    end
else
  @number = 1
end

Output:

BOB ROSS, Number: 1, Date of birth: 07/07/2007  
WILL SMITH, Number: 2, Date of birth: 08/08/2008  
JIM BOB, Number: 3, Date of birth: 09/09/2009  

You can also use a similar method for searching through an array:

number = File.readlines('Capgemini.txt')
number.each do |x|
  customer = x.split(',')
  customer_name = customer[0]
  customer_number = customer[1].gsub('Number: ', '').to_i
  customer_bday = customer[2].gsub('Date of birth: ', '')

  if customer_name == some_variable
    puts x
  end
end
