Expressing Algorithms - Pseudocode

Computer Science: Edexcel IGCSE, topic 1.1.3

Pseudocode

Pseudocode is a common way of representing an algorithm.

Pseudocode

Pseudocode

  • Pseudocode is a way to write out algorithms using code-like statements.
  • It is intended to be very readable, and easy to understand.
Purpose of pseudocode

Purpose of pseudocode

  • Pseudocode is not an actual programming language.
  • Pseudocode is used to plan algorithms, focusing on the logic and steps rather than language-specific syntax.
Edexcel pseudocode

Edexcel pseudocode

  • Edexcel has produced their own pseudocode which will be used in this course.
  • You do not need to write pseudocode exactly as they do, as long as it is clear what you are doing.
  • You do need to be able to understand their style of pseudocode.
