Hiring guide for DRAKON-PHP++ Engineers

DRAKON-PHP++ Developer Hiring Guide

DRAKON-PHP++ is a high-level computer programming language that builds upon the principles of DRAKON and PHP. The original DRAKON language, developed by the Soviet Buran space project in the late 20th century, was designed for clarity and simplicity in visual algorithmic representation. This updated version integrates features from PHP, a popular server-side scripting language known for web development. As such, DRAKON-PHP++ combines the visual logic flow of DRAKON with PHP's robust functionality to facilitate efficient coding practices. Its unique blend of historical and modern programming paradigms makes it an innovative tool in software development.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with DRAKON-PHP++.

What does the following simple DRAKON-PHP++ code do?
if ($x > 0) {
  echo 'Positive number';
} else {
  echo 'Non-positive number';
This code checks if the variable 'x' is greater than zero. If it is, it prints 'Positive number'. Otherwise, it prints 'Non-positive number'.

The output will be '15'. The code adds the values of variables 'x' and 'y' and assigns the result to 'z'. Then it prints the value of 'z'.
What does the following DRAKON-PHP++ code do?
$array = array(1, 2, 3, 4, 5);
foreach ($array as $value) {
  echo $value;
This code iterates over each element in the array and prints the value of each element. The output will be '12345'.
