Source Code
Source code is the human-readable set of instructions written by developers in a programming language, which defines the behavior and functionality of software applications. It serves as the foundational input for compilers or interpreters to translate into executable machine code or bytecode that computers can run. This includes files containing algorithms, data structures, and logic, typically organized into modules or classes.
Developers should understand source code as it is essential for creating, modifying, debugging, and maintaining software, enabling collaboration through version control systems like Git. It is used in all software development scenarios, from web and mobile apps to embedded systems, to ensure code quality, readability, and scalability. Mastery of source code principles supports best practices such as code reviews, refactoring, and documentation.
