Common error
Avoid using "source code" interchangeably with "executable files". "Source code" is human-readable and needs compilation or interpretation, whereas executable files are directly runnable by the computer.

FAQs
How can I access the "source code" of a program?
Access to "source code" depends on the software's licensing. Open-source software typically provides the "source code" freely, while proprietary software usually does not. Check the software's license agreement or the developer's website.
What's the difference between "source code" and machine code?
"Source code" is written in a human-readable programming language, while machine code is the binary code that a computer's processor executes directly. The "executable code" is generated from "source code" by a compiler.
Why is it important to comment your "source code"?
Commenting your "source code" makes it easier for others (and yourself in the future) to understand the code's functionality and logic. Good comments improve maintainability and reduce debugging time.
What does it mean when software is described as "open source"?
Open source software means the "source code" is freely available, allowing users to view, modify, and distribute the code. This promotes collaboration and transparency.
