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 string is some text. A substring is part of a bigger string. For example, "name" is a substring of "Hello, what's your name?".
This example creates a variable containing the string "What is your name" then displays the substring of the 5th and 6th characters ("is")
