What are some examples of switch case statements in Ruby?

In Ruby, the case statement allows you to execute different code based on the value of a variable. Here's a simple example:

fruit = 'apple'

case fruit
when 'apple'
  puts 'This is an apple.'
when 'banana'
  puts 'This is a banana.'
else
  puts 'Unknown fruit.'
end

Can you explain how the case statement works in that example?

Sure! In the example, the case statement checks the value of the fruit variable. If it matches 'apple', it executes the first block, printing 'This is an apple.' If it matches 'banana', it prints 'This is a banana.' If it doesn't match any cases, it goes to the else block.

Are there any other ways to use the case statement?

Yes, you can use ranges and even multiple conditions. For example:

number = 5

case number
when 1..5
  puts 'Number is between 1 and 5.'
when 6, 7, 8
  puts 'Number is 6, 7, or 8.'
else
  puts 'Number is greater than 8.'
end
