What are constants in Ruby?
An example of an AI chatbot conversation about constants in Ruby programming.
What are constants in Ruby?
In Ruby, constants are variables that are meant to remain unchanged throughout the program. They are defined with an uppercase letter.
Can you give me an example of a constant?
Sure! For example, you can define a constant like this: PI = 3.14. Here, PI is a constant.
What happens if I try to change a constant?
If you try to change a constant, Ruby will give you a warning, but it will still allow the change. For example, if you do PI = 3.14159, it will work but will show a warning.
Are there any naming conventions for constants?
Yes, constants should be written in all uppercase letters, and you can use underscores to separate words, like MAX_VALUE.
