6,649 PointsRuby quiz on hashes / methods
The quiz question is as follows:
Assign the value of the key name to the return value of the method get_name() in the contact hash. Assume that get_name() returns a string. Given the following:
contact_list = []
contact = {"name" => "", "phone_number" => "" }
my answer starts here:
contact_list = []
contact = {"name" => "", "phone_number" => "" }
def get_name() svalue = "Quiz" return svalue end
contact["name"] = get_name() puts contact["name"] puts contact.inspect
Which appears to work but the auto-grader states:
Bummer! The contact['name'] hash key did not have the value of the get_name() method.

contact["name"] = get_name()

6,649 PointsThat works great Maciej. The question should be updated by author to read:
"Assign the value of the key name to the return value of the method get_name() in the contact hash. Assume that get_name() HAS ALREADY BEEN DEFINED and returns a string."
[uppercase means the change requested]
That would have saved me a half hour of hair pulling. :)
