Say hello (lab)
Objectives
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:
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
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.
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".
Get all the tests to pass!
Once all of the tests are passing, use
learn submit
to submit your lab.
