compiler version at runtime

To determine the compiler version of Ruby at runtime, you can use the RUBY_VERSION constant. This constant returns a string representing the version of Ruby that is currently running.

Here are the steps to retrieve the compiler version at runtime:

  1. Use the RUBY_VERSION constant: In your Ruby code, you can access the RUBY_VERSION constant to get the version of the Ruby interpreter that is running the code. This constant is automatically defined by the Ruby interpreter.

  2. Print the value: To see the compiler version, you can use the puts method or any other appropriate output method to display the value of the RUBY_VERSION constant. For example:

puts RUBY_VERSION

This will output the version number of the Ruby interpreter that is running the code. For instance, if you are using Ruby version 2.7.4, the output will be:

2.7.4

By following these steps, you can easily retrieve the compiler version of Ruby at runtime.
