ruby program 1

Write a program in Ruby. First, go to https://rubyinstaller.org/downloads and download the latest version of Ruby without devkit (2.5.1-2). Install it, but you do not need to run ‘ridk install’ when it asks.

Create a code file with a .rb extension. In a command prompt, run:

ruby PathToYourFileFilename.rb

(replacing the placeholder text)

The program that you write should prompt the user to enter in information about gemstones (name, colour, and price), then display the information to the user after all of the information has been entered.

The basic functionality of this program is very basic, so most of your grade will depend on how effectively you make use of the programming concepts in Ruby, and how polished your program is. The following are some guidelines to help you make a better program.

Make it clear to the user what input is expected at each step.

Format your output in a way that looks nice and is easy to read.

Allow the price information to be inputted as an integer or a float, but display it as a currency.

Sort the gemstones before printing them out, but don’t reinvent the wheel.

Allow the user to input any number of gemstones.

Create a class for the gemstones.

Create a custom module and use it in your class. You are free to create whatever module you would find valuable, but I would suggest looking for functionality of the gemstone class that could also be used by other classes.

Feel free to come up with your own improvements to the program.

When you are finished, email me your code file (.rb)
