Episode 59 — Programming Concepts: Variables and Constants

In this episode, we look at two of the most important programming building blocks — variables and constants — as outlined in the CompTIA IT Fundamentals (ITF+) certification exam. Variables are used to store values that can change during program execution, while constants hold values that remain fixed. We’ll explain when to use each, how they are declared, and how scope affects their accessibility in a program.

We’ll also highlight common pitfalls like variable shadowing and improper initialization. Understanding how to manage and protect data through variables and constants is a core skill that directly applies to real-world coding as well as exam success. Produced by BareMetalCyber.com.
