This website aims to give a quick reference for VB.NET, Python, C# and pseudocode and is aimed primarily at teachers & students working towards a GCSE in Computer Science
VB.NET, Python and C# are programming languages designed to be understood and followed by computers. Pseudocode is not a programming language: it's written to be understood by humans so that they can turn it into any programming language.
Each exam board has published a document saying how they'll write pseudocode in their exams. The whole idea of syntax (a set of rules) for pseudocode is silly - it's not designed to be a programming language that is run by a computer. With this in mind, all exam boards state that you don't have to follow the syntax for 'their' version of pseudocode when you write out your own algorithms, but you should be able to understand their version of pseudocode when reading an algorithm in an exam.
Each skill has example code in VB.NET, Python, C# and Pseudocode for Edexcel, Eduqas and OCR GCSE.

A repeat until loop will keep repeating until a condition is met.
This is known as a post-conditioned loop because the program checks if the condition has been met after the code in the loop runs. This means that the loop will always run at least once.
It is also an example of indefinite iteration because the loop could carry on forever if the condition is never met.
This example program keeps asking the user "Are we nearly there yet?" until they say "yes"
