This website aims to give a quick reference for VB.NET, Python and C# and pseudocode and is aimed primarily at teachers & students working towards a GCSE or A Level 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 skill has example code in Python, C#. You can also enable VB.NET and Pseudocode for OCR GCSE if you'd find that useful.

A list is similar to an array: both allow more than one piece of data to be stored in the same variable.
It's not possible to add or remove data to an array after it's been set for the first time but it is possible to add or remove data to a list.
This example creates a list of strings called names. It adds 3 names to the list then removes the first one.
