In this episode, we explain the fundamental data types every programmer must know for the CompTIA IT Fundamentals (ITF+) certification exam. You’ll learn about character (char) types that store single letters or symbols, integer (int) types for whole numbers, floating-point (float) types for decimal values, and Boolean types for true/false logic.

We’ll discuss why selecting the right data type is crucial for efficiency, accuracy, and memory usage, as well as how type mismatches can lead to errors. Mastering these basics ensures you can interpret code snippets, predict program behavior, and tackle exam questions that test your understanding of data handling. Produced by BareMetalCyber.com.
