Welcome to another episode of our podcast on computer science fundamentals! Today, we're tackling Period 11: Scope of Variables, a crucial concept for writing bug-free and efficient code. Our main goal is to help you describe the scope of local and global variables. 🌍
Understanding Variable Scope
We'll start by defining scope as the region of a program where a variable can be used or "seen." We'll then distinguish between two main types:
- Global Variables: These are defined in the main part of a program and can be accessed from anywhere within the code. Think of them as variables with a wide, universal reach. We'll discuss their pros and cons, including their convenience but also the potential for security risks and increased memory ...
