Ask the right questions to secure the right ALGOL 60 talent among an increasingly shrinking pool of talent.
**ALGOL 60** is a computer programming language designed in 1958 by a team of international computer scientists led by John McCarthy. It was the first high-level programming language to be designed specifically for mathematical computing and became the standard language for research in theoretical computer science. ALGOL 60 was influential in the development of later programming languages, including C, C++, Java, and Python. * **Source:** [Wikipedia](https://en.wikipedia.org/wiki/ALGOL_60)
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
The logical operators in ALGOL 60 are 'and', 'or', and 'not'.
You can implement a loop in ALGOL 60 using the 'for' keyword. For example: 'for i := 1 step 1 until 10 do begin ... end'
'Begin' and 'end' are used to denote the start and end of a block of code or a compound statement in ALGOL 60.
The basic data types in ALGOL 60 are integer, real, boolean, and arrays.
You would declare an integer in ALGOL 60 using the keyword 'integer'. For example: 'integer x;'
In the fast-paced world of development, being able to learn quickly is a valuable skill. The candidate should show that they can pick up new concepts and technologies quickly.
While the position is for an ALGOL 60 developer, having experience with other languages can be beneficial. It can show that the candidate is adaptable and able to learn new languages quickly.
Communication is key in a development role. The candidate should be able to effectively communicate their ideas and understand the ideas of others.
Most development work is done in teams. The candidate should be able to work well with others and contribute to a positive team environment.
Being able to solve problems is a key skill for any developer. The candidate should be able to use ALGOL 60 to solve a variety of problems.
This is crucial as the job position is for an ALGOL 60 developer. The candidate should be able to demonstrate a deep understanding of the language.
The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.
ALGOL 60 does not have built-in support for exception handling. You would need to implement your own error checking and handling logic.
In pass by value, the actual value is passed. In pass by name, a reference to the variable is passed, allowing the procedure to modify the original variable.
The arithmetic operators in ALGOL 60 are '+', '-', '*', '/', and 'div'.
You can write a function in ALGOL 60 using the 'procedure' keyword. For example: 'procedure square(x); real x; begin real square; square := x * x; end'
'Own' variables retain their values between procedure calls, while 'local' variables do not. They are reinitialized each time the procedure is called.
A skilled ALGOL 60 engineer should possess strong problem-solving skills, deep understanding of ALGOL 60 and its applications, and good communication abilities. Red flags include lack of experience with the language or inability to explain complex concepts clearly.
BEGIN INTEGER a; a := 5; PRINT(a); ENDBEGIN REAL x; x := 3.14; PRINT((x * 2) / 3); ENDBEGIN INTEGER array[5]; FOR i := 1 STEP 1 UNTIL 5 DO array[i] := i * 2; PRINT(array); ENDBEGIN BOOLEAN flag; flag := TRUE; IF flag THEN PRINT('True') ELSE PRINT('False'); ENDBEGIN INTEGER x, y; x := 5; y := 10; IF x < y THEN PRINT('x is less than y') ELSE PRINT('x is not less than y'); ENDBEGIN INTEGER x, y, z; x := 5; y := 10; z := 15; IF x < y AND y < z THEN PRINT('x is less than y and y is less than z') ELSE PRINT('x is not less than y or y is not less than z'); ENDThe final few interview questions for a ALGOL 60 candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.
'Real' data type is used to represent floating point numbers, while 'integer' data type is used to represent whole numbers.
ALGOL 60 does not have built-in string manipulation functions. You would need to implement your own functions for string manipulation.
You can implement recursion in ALGOL 60 by writing a procedure that calls itself. For example, a recursive factorial function could be written as: 'procedure factorial(n); integer n; begin integer factorial; if n = 0 then factorial := 1 else factorial := n * factorial(n - 1); end'
'If' statements are used for conditional execution based on a single condition, while 'case' statements are used for conditional execution based on multiple conditions.
The control structures in ALGOL 60 are 'if' statements, 'for' loops, 'while' loops, and 'goto' statements.
