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.

Not equal to

You can test if two expressions are the same using the equal to or not equal to operator.

An expression can be a variable or combination of variables & data (e.g. 1 + 1)

An operator is a symbol that means add, subtract or something similar.

This example asks the user to enter a temperature of a bath (in degrees Celsius) and then follows the following rules:

Equal to 37 degrees: says "Perfect - that's body temperature"

Not equal to 37 degrees: "Not body temperature"

temperature = int(input("What's the temperature of the bath?") if temperature == 37: print("Perfect - that's body temperature") if temperature != 37: print("Not body temperature")

Console.WriteLine("What's the temperature of the bath?"); int temperature = int.Parse(Console.ReadLine()); if(temperature == 37) { Console.WriteLine("Perfect - that's body temperature"); } if(temperature != 37) { Console.WriteLine("Not body temperature"); }
