CLIvia generator

Start the program

When the program starts, we will initialize the scores filename, the array of questions, and the user's score.

The filename value is scores.json by default, but the user can pass a custom filename as a command-line argument. For example ruby clivia_generator.rb custom_scores.json

ruby clivia_generator.rb

When "random" is selected

You should load 10 random questions from the API. Once they are loaded you will show each of them one by one, allowing the user to select one of the options.

Answers could come encoded with some special characters, use the HTMLEntities gem to decode it, and show the text as expected.

Once the user gives an answer you should compare it with the correct answer delivered by the API. Then give the user a correct or incorrect response message.

• Error message when invalid option: "Invalid option"

If the user types y or Y, then the program will prompt the user to assign a name to the score.

Once the name is given by the user, we will append the recent score to the file pointed by the filename we declared at initialization, this file should be a JSON and should start empty.

In case the user didn't type a name, we will add the score as "Anonymous" to the scores' file.

Finally, show back the welcome message with the options menu.

💡 In case you are using JSON.parse within `File.read` to grab scores data from the declared file, rescue `Errno::ENOENT` to take care of the error when the file is empty to be able to keep going.

When scores action is selected

Last but not least, when scores action is selected you should show the scores that were saved previously, these scores should be shown in order from top to bottom and inside a table that includes the title Top Scores, and the headings Name ****and Score.

Once the table is shown, we will prompt the user with the welcome menu again so they can keep going with another Clivia.
