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.
  • Search for a specific skill

Create a 2D array
   

If an array is like a list of data, a 2d array is like a grid of data where the data is stored in one variable but organised into rows and columns like a spreadsheet.

This example stores details of 3 different fruit for a supermarket.

It will then display the colour of the first fruit.

The first index will select the row then the second index selects the column. 

fruit = [["Plumb", "Purple"], ["Apple", "Red"], ["Banana", "Yellow"]] print(fruit[0][1])
string[,] fruit = { {"Plumb", "Purple"}, {"Apple", "Red"}, {"Banana", "Yellow"} }; Console.WriteLine(fruit[0,1]);
