Peter Naur's Revised Algol 60(REVISED ALGOL 60 ) Developer Hiring Guide

Peter Naur's Revised Algol 60 is a historically significant computer programming language, developed in the 1960s as an enhancement to the original ALGOL 60. As a leading figure in its creation, Naur significantly contributed to its structure and syntax. The Revised Algol 60 was one of the first languages to introduce block structures and lexical scope, laying groundwork for many modern programming languages. It was mainly used for scientific computing and has been influential in teaching structured programming concepts. The information about this language can be found from various historical sources including "The Design of Computer Programming Languages" by S Tucker Taft & Robert A Duff.

First 20 minutes

General Peter Naur's Revised Algol 60(REVISED ALGOL 60 ) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Peter Naur's Revised Algol 60(REVISED ALGOL 60 ) application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What are the key features of Revised Algol 60?
Revised Algol 60, also known as Algol 60, is a language that introduced block structure, lexical scope, recursion, and complex data types. It also supports arrays and procedures as first-class objects.
How would you declare an array in Revised Algol 60?
In Revised Algol 60, an array can be declared using the 'array' keyword followed by the array dimensions. For example, 'array A[1:10]' declares an array A with 10 elements.
What is the purpose of the 'begin' and 'end' keywords in Revised Algol 60?
The 'begin' and 'end' keywords in Revised Algol 60 are used to denote the start and end of a block of code. They are similar to the curly braces '{}' in languages like C and Java.
How would you define a procedure in Revised Algol 60?
In Revised Algol 60, a procedure is defined using the 'procedure' keyword, followed by the procedure name, parameters, and the procedure body enclosed in 'begin' and 'end' keywords. For example, 'procedure add(x, y); begin return x + y; end;' defines a procedure to add two numbers.
What is the significance of the 'own' keyword in Revised Algol 60?
The 'own' keyword in Revised Algol 60 is used to declare a variable that retains its value between calls to the procedure in which it is declared. It is similar to the 'static' keyword in C.

Next 20 minutes

Specific Peter Naur's Revised Algol 60(REVISED ALGOL 60 ) development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

How would you implement recursion in Revised Algol 60?
Recursion in Revised Algol 60 can be implemented by having a procedure call itself. For example, a recursive procedure to calculate factorial can be defined as 'procedure factorial(n); begin if n = 0 then return 1; else return n * factorial(n - 1); end;'.
Describe the difference between 'value' and 'name' parameters in Revised Algol 60.
'Value' parameters in Revised Algol 60 are similar to pass-by-value parameters in other languages, where a copy of the argument is passed to the procedure. 'Name' parameters, on the other hand, are similar to pass-by-reference parameters, where the procedure has access to the original argument.
How would you handle errors in Revised Algol 60?
Revised Algol 60 does not have built-in error handling mechanisms like try-catch blocks. Errors have to be handled manually by checking for error conditions and taking appropriate actions.
What are the data types supported by Revised Algol 60?
Revised Algol 60 supports several data types including integer, real, boolean, character, and array. It also supports complex data types defined by the user.
How would you perform type conversion in Revised Algol 60?
Type conversion in Revised Algol 60 can be performed using built-in functions like 'int', 'real', 'bool', and 'char' that convert their argument to the corresponding type.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Peter Naur's Revised Algol 60(REVISED ALGOL 60 ).

What does the following basic Algol 60 code do?
BEGIN INTEGER X; X := 5; PRINT((X)) END
This code declares an integer variable X, assigns the value 5 to X, and then prints the value of X. The output will be 5.
What does the following Algol 60 code snippet do?
BEGIN REAL ARRAY A[1:10]; FOR I := 1 STEP 1 UNTIL 10 DO A[I] := I; PRINT((A)) END
This code declares a real array A with 10 elements. It then uses a FOR loop to assign each element in the array a value equal to its index. Finally, it prints the array A.
What does this Algol 60 code snippet do?
BEGIN INTEGER ARRAY A[1:5]; FOR I := 1 STEP 1 UNTIL 5 DO A[I] := I*I; PRINT((A)) END
This code declares an integer array A with 5 elements. It then uses a FOR loop to assign each element in the array a value equal to the square of its index. Finally, it prints the array A.
What does this Algol 60 code snippet do?
BEGIN INTEGER PROCEDURE P(X); VALUE X; INTEGER X; BEGIN X := X*X; PRINT((X)) END; P(5) END
This code declares a procedure P that takes an integer X as argument, squares it, and prints the result. The procedure is then called with the argument 5. The output will be 25.

Wrap-up questions

Final candidate for Peter Naur's Revised Algol 60(REVISED ALGOL 60 ) 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 Peter Naur's Revised Algol 60(REVISED ALGOL 60 ) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What is the role of the 'go to' statement in Revised Algol 60?
The 'go to' statement in Revised Algol 60 is used for unconditional branching. It transfers control to the statement labeled with the identifier following the 'go to' keyword.
How would you implement a loop in Revised Algol 60?
Loops in Revised Algol 60 can be implemented using the 'for' statement. For example, 'for i := 1 step 1 until 10 do begin ... end;' implements a loop that iterates 10 times.
Describe the difference between 'in' and 'out' procedures in Revised Algol 60.
'In' procedures in Revised Algol 60 are procedures that are defined inside another procedure, while 'out' procedures are defined outside all other procedures. 'In' procedures have access to the variables of the enclosing procedure, while 'out' procedures do not.
