Try your best to work each of the problems before moving on.
Find:
• The Ruby API
• The free online version of Programming Ruby: The Pragmatic Programmer’s Guide [TFH08]
• A method that substitutes part of a string
• Information about Ruby’s regular expressions
• Information about Ruby’s ranges
Do:
• Print the string “Hello, world.”
• For the string “Hello, Ruby,” find the index of the word “Ruby.”
• Print your name ten times.
• Print the string “This is sentence number 1,” where the number 1changes from 1 to 10.
• Run a Ruby program from a file.
• Bonus problem: If you’re feeling the need for a little more, write a program that picks a random number. Let a player guess the number, telling the player whether the guess is too low or too high. (Hint: rand(10) will generate a random number from 0 to 9, and gets will read a string from the keyboard that you can translate to an integer.)
