Say Hello

Objectives

  1. Build a method that can be called with an optional argument by defining that method with a default argument.

Instructions

You will build a method called say_hello. This method should accept the argument of a person's name. It then should print "Hello " with the name followed by an exclamation point (don't forget that space after the "Hello"). For instance:

# I call on the method, say_hello, and give it the string "Gabriela" 
say_hello("Gabriela")

# The method prints this text to the screen:
Hello Gabriela!

There is one more thing this method should do: if you call on this method and forget to give it the name of a person, it should just say, "Hello Ruby Programmer!". Use a default argument to accomplish this!

Steps

  1. Run learn to see where you stand.
  • You probably got two NoMethodErrors. This means the test was looking for a method called say_hello but couldn't find it.
  1. Define the method in say_hello.rb
  • Run learn again. Are you getting a different error? If you haven't seen this error, guess what it's trying to tell you then Google it with the word "ruby".
  1. Get all the tests to pass!
  2. Once all of the tests are passing, use learn submit to submit your lab. Or alternatively, you can stage and commit your code; push it up to your fork; and submit a pull request.
