Intro to IGCSE Pseudocode

Pseudocode is a way of describing what happens in a computer program. It is a list of instructions that show how the program will work. Pseudocode is set out with the same structure as a programming language, but it is not a programming language in itself.

Pseudocode can be used to show people who do not know a particular programming language how the program works. Additionally, programmers can use it to plan and design programs.
