Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Elan Programming Language.

What does the following simple Elan code do?
let x = 5 in x * x
This code declares a variable 'x' with a value of 5 and then multiplies 'x' by itself. The result is 25.
What will be the output of the following Elan code?
let x = 5 in let y = 2 in x * y
This code declares two variables 'x' and 'y' with values 5 and 2 respectively. Then it multiplies 'x' by 'y'. The output will be 10.
What does the following Elan code do?
let arr = [1, 2, 3, 4, 5] in List.map (fn x => x * 2) arr
This code declares an array 'arr' with values from 1 to 5. Then it uses the 'List.map' function to multiply each element of the array by 2. The result is a new array [2, 4, 6, 8, 10].
What will be the output of the following Elan code?
let x = ref 0 in let _ = Thread.fork (fn () => x := !x + 1) in !x
This code declares a reference 'x' with a value of 0. Then it creates a new thread that increments the value of 'x'. The output will be 0 or 1, depending on whether the main thread reads the value of 'x' before or after the new thread increments it.

Wrap-up questions

Final candidate for Elan Programming Language Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle Elan Programming Language application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What is the use of the 'super' keyword in Elan?

In Elan, 'super' is a keyword that refers to the parent class. It is used to call the constructor of the parent class or to access the properties and methods of the parent class.

How would you create and use an array in Elan?

In Elan, you can create an array using the 'new' keyword followed by the data type, and then specify the size of the array. To use an array, you can assign values to each element using the array index.

What are the different types of inheritance supported in Elan?

Elan supports several types of inheritance including single, multiple, multilevel, hierarchical, and hybrid inheritance.
