FAQs on Ruby Programming Tutorial-14-Multidimensional Arrays And each loop Video Lecture - Introduction to Coding with Ruby (in Hindi) - Back-End Programming
| 1. What is a multidimensional array in Ruby? |  |
Ans. A multidimensional array in Ruby is an array that contains one or more arrays as elements. It can be visualized as a grid or a table with rows and columns, where each element can be accessed using multiple indices.
| 2. How can I create a multidimensional array in Ruby? | |
Ans. To create a multidimensional array in Ruby, you can simply nest arrays within an array. For example, you can create a 2-dimensional array with two rows and three columns using the following syntax:
```ruby
array = [[1, 2, 3], [4, 5, 6]]
```
| 3. How do I access elements in a multidimensional array in Ruby? | |
Ans. You can access elements in a multidimensional array in Ruby by specifying the indices of both the outer array and the inner array. For example, to access the element at the second row and third column of a 2-dimensional array named `array`, you can use the following syntax:
```ruby
element = array[1][2]
```
Note that array indices start from 0 in Ruby.
| 4. Can I use the `each` loop with a multidimensional array in Ruby? | |
Ans. Yes, you can use the `each` loop with a multidimensional array in Ruby. However, keep in mind that the `each` loop only iterates over the outer array, not the inner arrays. If you need to access each element in the inner arrays, you can use nested `each` loops or other iteration methods like `map` or `flatten`.
| 5. How can I modify elements in a multidimensional array in Ruby? | |
Ans. To modify elements in a multidimensional array in Ruby, you can use the same syntax as accessing elements. Simply specify the indices of both the outer array and the inner array and assign a new value to it. For example, to modify the element at the second row and third column of a 2-dimensional array named `array`, you can use the following syntax:
```ruby
array[1][2] = new_value
```
