tailieunhanh - HUMBLE LITTLE RUBY BOOK

In the following book, I will be using Ruby to test all the Ruby code. Each example can be copied and pasted directly into irb/fxri and it should work famously. I have done so with each one to make sure they run. Each time I am showing output from irb, you will see a → character followed by the output. Any method or variable name or code/system related text is typeset in this font for easy discernment from other text.
