1. What is a class in Ruby programming?
Ans. In Ruby programming, a class is a blueprint or a template that defines the properties and behaviors of an object. It serves as a blueprint for creating objects with similar characteristics.
2. What is the difference between a variable and an object in Ruby programming?
Ans. In Ruby programming, a variable is a name that represents a value or an object. It acts as a reference to the object stored in memory. On the other hand, an object is an instance of a class that holds data and behaviors defined by the class.
3. How do you define a class in Ruby programming?
Ans. To define a class in Ruby, you use the 'class' keyword followed by the class name. For example, to define a class named 'Person', you would write: ``` class Person # class body end ```
4. What are instance variables in Ruby programming?
Ans. Instance variables in Ruby programming are variables that belong to an instance of a class. They are prefixed with the '@' symbol and can be accessed and modified within the instance methods of the class. Each instance of the class has its own set of instance variables.
5. How are objects created in Ruby programming?
Ans. In Ruby programming, objects are created by calling the 'new' method on a class. This initializes a new instance of the class and returns it as an object. For example, to create an object of the 'Person' class, you would write: ``` person = Person.new ```
