Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with AdaCore Script Z4.

What does this simple Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Hello is
 Put_Line ("Hello, world!");
end Hello;
This code prints 'Hello, world!' to the standard output.
What does this Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Display is
 X : Integer := 10;
 Put ("The value of X is " & Integer'Image (X));
end Display;
This code prints 'The value of X is 10' to the standard output.
What will be the output of this Ada code snippet?
with Ada.Text_IO; use Ada.Text_IO;
procedure Array_Print is
 type Int_Array is array (1 .. 5) of Integer;
 A : Int_Array := (1, 2, 3, 4, 5);
 for I in A'Range loop
 Put (Integer'Image (A (I)) & " ");
 end loop;
end Array_Print;
This code prints the elements of an array, '1 2 3 4 5', to the standard output.
What does this Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Task_Identification;
procedure Concurrency is
 task T is
 entry Start;
 end T;
 task body T is
 Put_Line ("Task T started");
 end T;
 T_Obj : T;
end Concurrency;
This code creates a concurrent task T and starts it. The task prints 'Task T started' to the standard output.

Wrap-up questions

Final candidate for AdaCore Script Z4 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 AdaCore Script Z4 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between concurrency and parallelism in AdaCore Script Z4?
Concurrency in AdaCore Script Z4 refers to the concept of making progress on more than one task at the same time. Parallelism, on the other hand, refers to the execution of multiple tasks simultaneously on different cores or processors.
How would you manage a large AdaCore Script Z4 project?
I would use a version control system to manage the source code, employ a modular design to manage complexity, and use the AdaCore's tools for project management, debugging, and testing.
What are the key differences between AdaCore Script Z4 and Java?
AdaCore Script Z4 is better suited for real-time and embedded systems due to its better performance and safety features. On the other hand, Java is more widely used for general-purpose programming and has a larger standard library.
