2. Pseudocode

Pseudocode is a text-based way of setting out an algorithm. Here is a very simple example:

  • Fetch a tea cup
  • Boil some water
  • Place a tea bag into the cup
  • Pour on boiling water
  • Stir teabag
  • Remove teabag
  • END

Pseudocode is not a formal computer language and so it has no particular rules governing how it should be written. You may see many different versions in books, on the web and even in your exam papers.

What is important is that pseudocode should be easy to read, unambiguous and error free. Especially because programmers often use it to form the basis of their programming code.
