attr_accessor ruby

The attr_accessor method in Ruby is a shorthand way to define getter and setter methods for instance variables. It provides a way to read and write the values of instance variables without the need to manually define separate methods for each variable.

Here's an explanation for each step of using attr_accessor in Ruby:

Start by defining a class in Ruby. This can be done using the class keyword followed by the name of the class and the end keyword to close the class definition.
Inside the class definition, use the attr_accessor method followed by the name of the instance variable you want to define accessors for. For example, if you want to define accessors for an instance variable called name, you would use attr_accessor :name.
The attr_accessor method automatically creates two methods for the specified instance variable:
A getter method, which is used to retrieve the current value of the instance variable. In our example, the getter method for name would be name.
A setter method, which is used to assign a new value to the instance variable. In our example, the setter method for name would be name=.
With the getter and setter methods created by attr_accessor, you can now read and write the value of the instance variable directly. For example, to read the value of name, you would use object.name, and to assign a new value to name, you would use object.name = "new name".

By using attr_accessor, you can save time and reduce code duplication by automatically generating getter and setter methods for your instance variables.
