- Define methods that use iteration and control the return values of those methods.
- Define methods that call other methods.
In this lab you'll be learning how to iterate through an array and output the results in different ways. Write your code in the conference_badges.rb file and you can run the test suite using the learn command.
You're hosting a conference and need to print badges for the speakers. Each badge should read: "Hello, my name is _____." Write a badge_maker method that, when provided a person's name, will create and return this message. E.g.:
badge_maker("Arel")
=> "Hello, my name is Arel."The list of speakers for your conference has been finalized. Your conference speakers are: Edsger, Ada, Charles, Alan, Grace, Linus, and Matz. How you scored these luminaries is beyond me, but way to go! Now you'll want to get their badges printed.
- Write a
batch_badge_creatormethod that takes an array of names as an argument and returns an array of badge messages.
You just realized that you also need to give each speaker a room assignment. Write a method called assign_rooms that takes the list of speakers and assigns each speaker to a room. Make sure that each room only has one speaker.
- You have rooms 1-7.
- return a list of room assignments in the form of: "Hello, _____! You'll be assigned to room _____!"
- Hint: Think about how you will assign a room number to each person. Array items are indexed, meaning that you can access each element by its index number. When you are iterating through an array, you can keep track of the index number of the current iteration using an enumerator method called
each_with_index. - Hint: Remember that the return value of the
eachmethod is the original array that you are calling it on. How can you collect or store the room assignment strings you are creating as you iterate and return them at the end of yourassign_roomsmethod? Google or use Ruby Docs to find the correct method.
Now you have to tell the printer what to print. Create a method called printer that will output first the results of the batch_badge_creator method and then of the assign_rooms method to the screen.
- Hint: Remember that methods can call other methods. If the return value of
assign_roomsis an array of room assignments, how can you print out each assignment? You'll need to iterate over your array of room assignments in order toputsout each individual assignment.
