Programming concepts: Variables and constants

This is the third of three GCSE livestream sessions dedicated to programming concepts for GCSE computer science. Over three sessions, you will learn about some of the fundamental concepts that almost all programs consist of, which allow them to achieve their particular goal. In this session, you will learn about how variables and constants are used in programs. This includes: Knowing the concept of a variable as a named container Understanding the importance of giving variables meaningful identifiers Understanding how variables can be declared and initialised, and how different programming languages approach this Knowing that values are assigned to variables Understanding how constants differ from variables, the benefit of using constants rather than variables, and how some programming languages differ in the way they treat constants Understanding the naming conventions for identifiers and the benefits of using naming conventions
