FAQs on Ruby Programming Tutorial-15-Files Video Lecture - Introduction to Coding with Ruby (in Hindi) - Back-End Programming
| 1. What is the purpose of back-end programming in Ruby? |  |
Ans. Back-end programming in Ruby involves writing code that runs on the server side of a web application. It is responsible for handling data storage, processing user requests, and generating responses to be sent to the client-side.
| 2. How can I read data from a file in Ruby? | |
Ans. In Ruby, you can read data from a file using the File class. First, you need to open the file using the File.open method, specifying the file path and the mode (e.g., "r" for reading). Then, you can use the File.read method to read the entire file contents or File.readlines to read it line by line.
| 3. How do I write data to a file in Ruby? | |
Ans. To write data to a file in Ruby, you can use the File class as well. First, you need to open the file using the File.open method, specifying the file path and the mode (e.g., "w" for writing). Then, you can use the File.write method to write a string to the file, or you can use the File.puts method to write multiple lines.
| 4. Can I append data to an existing file in Ruby? | |
Ans. Yes, you can append data to an existing file in Ruby by opening the file in the append mode ("a") using the File.open method. This will ensure that any new data you write will be added to the end of the file without overwriting the existing content.
| 5. How can I check if a file exists in Ruby? | |
Ans. In Ruby, you can check if a file exists using the File.exist? method. This method takes a file path as an argument and returns true if the file exists at that path, or false otherwise. You can use this method to conditionally perform actions based on the existence of a file before attempting to read or write to it.
