Introduction

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.

Top Tips:

  • Explore the different categories of skills at the top of this page
    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.

Real constants
   

Reals are numbers that can contain a decimal place.

Constants store a value that is set once and then never changes.

Real constants let you give a decimal number a name so you can use it to make your code easier to read or to set options for your code that the user wont be able to change.

In this example, a constant called PI is set to the real value of 3.141

 

# Create a new constant called PI PI = 3.141
// Create a new constant called PI const double PI = 3.141;
