FAQs on Ruby Programming Tutorial-7-Arrays Video Lecture - Introduction to Coding with Ruby (in Hindi) - Back-End Programming
| 1. What is an array in Ruby programming? |  |
| 2. How can I create an array in Ruby? | |
Ans. To create an array in Ruby, you can use the square bracket notation. For example, you can create an array of numbers like this:
```
numbers = [1, 2, 3, 4, 5]
```
You can also create an empty array and then add elements to it later using the `push` method.
| 3. How can I access elements in an array in Ruby? | |
Ans. You can access elements in an array by their index. The index starts from 0 for the first element and increments by 1 for each subsequent element. For example, to access the second element of an array called `fruits`, you can use `fruits[1]`.
| 4. How can I add elements to an array in Ruby? | |
Ans. There are multiple ways to add elements to an array in Ruby. You can use the `push` method to add elements at the end of the array, like this:
```
fruits = ["apple", "banana"]
fruits.push("orange")
```
You can also use the `<<` operator or the `concat` method to add elements to an array.
| 5. Can I remove elements from an array in Ruby? | |
Ans. Yes, you can remove elements from an array in Ruby using various methods. For example, you can use the `pop` method to remove the last element from the array. You can also use the `delete_at` method to remove an element at a specific index, or the `delete` method to remove a specific value from the array.
