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.

Create and use a procedure with parameters
   

A procedure is a section of code that has a name, that you can re-use to do something useful.

Parameters are variables that allow you to send data to the procedure to customise what it does or how it works. 

A procedure definition is the code that tells the computer what to do whenever that procedure runs. The parameters are the variables named in brackets after the procedure name.

The procedure wont actually do anything until you call it.

This example defines a procedure which will display a random number. It has two parameters which allow you to set the minimum and maximum number the random number will be between.  

This procedure is called to show a random number between 10 and 20 and then called again to choose a random number between 50 and 100.

import random # define the procedure def show_random_between(min, max): print(random.randint(min, max)) # call the procedure show_random_between(10, 20) show_random_between(50, 100)
// define the procedure void showRandomBetween(int min, int max) { Random r = new Random(); int number = r.Next(min, max); Console.WriteLine(number); } // call the procedure showRandomBetween(10, 20); showRandomBetween(50, 100);
