FAQs on Ruby Programming Tutorial-13-Gets chomp Video Lecture - Introduction to Coding with Ruby (in Hindi) - Back-End Programming

1. What is the purpose of the "gets" method in Ruby?
Ans. The "gets" method in Ruby is used to obtain user input from the console. It allows the program to pause and wait for the user to enter a value.
2. What does the "chomp" method do in Ruby?
Ans. The "chomp" method in Ruby is used to remove the trailing newline character from a string. This is useful when using the "gets" method to get user input, as it eliminates the newline character that is automatically added at the end.
3. How does the combination of "gets" and "chomp" work in Ruby?
Ans. When used together, the "gets" method is used to obtain user input and the "chomp" method is used to remove any trailing newline character from the input. This ensures that the input is clean and can be processed effectively.
4. Can you provide an example of using "gets.chomp" in a Ruby program?
Ans. Certainly! Here's an example: ```ruby puts "Enter your name:" name = gets.chomp puts "Hello, #{name}!" ``` In this example, the program prompts the user to enter their name. The input is obtained using the "gets" method, and then the "chomp" method is used to remove the newline character. Finally, the program greets the user using their name.
5. Are there any potential issues when using "gets.chomp" in Ruby?
Ans. One potential issue when using "gets.chomp" is that the newline character is removed regardless of whether it is present or not. This means that if the user does not enter any input and just presses Enter, the program will receive an empty string. It's important to handle such cases and perform appropriate validation to avoid unexpected behavior.
