High-level language code is considered readable primarily because it is designed to be easily understood by humans. This readability is achieved through the use of meaningful names for variables, functions, and classes, as well as the inclusion of documentation that explains how the code works. When programmers write code in high-level languages, they often use clear and descriptive identifiers that represent their purpose, which helps others (and themselves) comprehend the code more effectively.
In addition to meaningful names, high-level languages typically employ structured syntax that resembles natural language, allowing developers to grasp the logic quickly without needing to understand complex machine instructions. The combination of these practices ensures that the code is not only functional but also approachable and maintainable over time, making it easier for multiple developers to collaborate.
While other choices touch on aspects of programming, they do not contribute directly to the readability of high-level language code in the same way. For example, using only numeric values would likely result in code that is cryptic and hard to understand, as would code that prioritizes execution speed over clarity. Simplified functions and procedures can help organize code but are not the defining factor for readability.
