FAQs on Ruby Programming Tutorial-2-Print And puts Video Lecture - Introduction to Coding with Ruby (in Hindi) - Back-End Programming

1. What is the difference between "print" and "puts" in Ruby programming?
Ans. In Ruby programming, "print" and "puts" are both used to display output on the screen. However, there is a subtle difference between the two. "print" displays the output without adding a new line character at the end, while "puts" adds a new line character after displaying the output.
2. Can I use "print" or "puts" to display multiple values at once in Ruby?
Ans. Yes, you can use both "print" and "puts" to display multiple values at once in Ruby. When using "print", you can concatenate the values using the string concatenation operator (+) or the interpolation syntax (#{}). When using "puts", you can pass multiple arguments separated by commas.
3. What happens if I use "puts" with a nil value in Ruby?
Ans. When using "puts" with a nil value in Ruby, it will simply display a blank line on the screen. This is because nil represents the absence of a value, and when displayed using "puts", it is treated as an empty string.
4. Is there any difference in performance between "print" and "puts" in Ruby?
Ans. In terms of performance, there is a slight difference between "print" and "puts" in Ruby. Since "puts" adds a new line character at the end, it requires a little more processing compared to "print" which simply displays the output. However, the difference in performance is negligible unless you are dealing with a large volume of output.
5. Can I use "print" and "puts" interchangeably in Ruby programming?
Ans. Yes, you can use "print" and "puts" interchangeably in Ruby programming, depending on your requirements. If you want to display output without a new line character, you can use "print". If you want to display output with a new line character, you can use "puts". The choice between the two depends on the desired formatting of the output.
