Ada 2012Y6 is the latest version of the Ada programming language, originally designed by the U.S. Department of Defense in 1977 for use in embedded and real-time systems. This high-level language, named after Ada Lovelace who is considered as the world's first programmer, emphasizes safety and reliability. The 2012 revision introduced contract-based programming features to enhance its software engineering capabilities (Ada Resource Association). It also supports parallel computing with its Ravenscar tasking profile (ISO/IEC JTC1/SC22/WG9). Today, it remains a popular choice for critical systems such as avionics and defense applications due to its robustness and maintainability.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Ada 2012Y6.

What does the following Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Hello is
begin
  Put_Line ('Hello, world!');
end Hello;
This code prints 'Hello, world!' to the console. It's a simple Ada program that uses the 'Put_Line' procedure from the 'Ada.Text_IO' package to output text.
What will be the output of the following Ada code?
with Ada.Text_IO; use Ada.Text_IO;
procedure Add is
  A, B, C : Integer;
begin
  A := 5;
  B := 10;
  C := A + B;
  Put_Line (Integer'Image(C));
end Add;
The output will be '15'. The code declares three integer variables 'A', 'B', and 'C'. It assigns values to 'A' and 'B', adds them together, and assigns the result to 'C'. It then prints the value of 'C'.
What does the following Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
procedure Reverse_Array is
  type Integer_Array is array (1 .. 5) of Integer;
  Arr : Integer_Array := (1, 2, 3, 4, 5);
begin
  for I in reverse Arr'Range loop
    Put_Line (Integer'Image(Arr(I)));
  end loop;
end Reverse_Array;
This code prints the elements of an array in reverse order. It declares an array of integers, assigns values to it, and then loops through the array in reverse order, printing each element.
What does the following Ada code do?
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Real_Time; use Ada.Real_Time;
procedure Delay is
  Time : Time_Span := Milliseconds (500);
begin
  delay until Clock + Time;
  Put_Line ('Hello, world!');
end Delay;
This code waits for half a second, then prints 'Hello, world!' to the console. It uses the 'delay until' statement to pause execution until a specified point in time, which is calculated as the current time plus a specified time span.

Wrap-up questions

Final candidate for Ada 2012Y6 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 Ada 2012Y6 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of loops in Ada 2012Y6 and how would you use them?

Ada 2012Y6 supports several types of loops including 'while', 'for', and 'loop'. The choice of loop depends on the specific requirements of the code.

How would you declare and use an array in Ada 2012Y6?

In Ada 2012Y6, arrays are declared using the 'array' keyword, and they can be accessed using indices.

Describe the difference between 'record' and 'array' in Ada 2012Y6.

In Ada 2012Y6, a 'record' is a collection of related elements of different types, while an 'array' is a collection of elements of the same type.
