BACE Ruby Review #1

Hi All,

If you get the chance, please check out the Ruby quiz below.

I plan to have a similar quiz after every class.

Don't worry, this is not like a quiz from back in school. It's not meant to trip you up, and there won't be a grade. It is meant as a review of what we've covered in the course so far.

I will go over the answers at the start of the class next week.

Here you go:

When was Ruby created?

Who created it?

Is Ruby an interpreted language or a compiled language?

What's the difference?

What can you use irb for?

How much does Ruby cost?

How can you tell which version of Ruby is installed on a computer?

What are the 'nouns' of object oriented programming called?

What are the 'verbs' called?

Name three Ruby classes that we talked about last week.

Name three methods.

What are all methods called on?

What do all methods return?

What does the nil object mean?

What is an array?

What are two ways to create a String object?

What are two ways to create a Fixnum object?

What are two great reasons for learning Ruby?

What is the difference between the puts method and the print method?

See you on Monday June 8th.
