FAQs on Ruby Programming Tutorial-10-Variable Number of Parameters Video Lecture - Introduction to Coding with Ruby (in Hindi) - Back-End Programming

1. What is a variable number of parameters in Ruby programming?

Ans. A variable number of parameters, also known as a variable-length argument list, allows a method in Ruby programming to accept any number of arguments. This means that the number of parameters passed to the method can vary at runtime.

2. How can I define a method with a variable number of parameters in Ruby?

Ans. In Ruby, you can define a method with a variable number of parameters by prefixing the parameter name with an asterisk (*). For example, def method_name(*parameters_name). The parameters_name will become an array containing all the passed arguments.

3. Can I mix regular parameters and a variable number of parameters in a Ruby method?

Ans. Yes, you can mix regular parameters and a variable number of parameters in a Ruby method. Simply define the regular parameters before the asterisk (*). The regular parameters will be assigned the passed values, and the variable number of parameters will be collected into an array.

4. How do I access the variable number of parameters inside a Ruby method?

Ans. To access the variable number of parameters inside a Ruby method, you can treat them as an array. You can use array methods like indexing, iteration, or any other array operation to manipulate or retrieve the passed arguments.

5. Can I pass no arguments to a method with a variable number of parameters in Ruby?

Ans. Yes, you can pass no arguments to a method with a variable number of parameters in Ruby. In such cases, the variable number of parameters will be an empty array. You can handle this scenario by checking the length of the array and performing specific actions accordingly.
