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? |  |
| 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.
