What does it mean if a language is interpreted?

• A. The code is compiled after execution
• B. The code is executed sequentially without pre-compilation
• C. The code is assessed for errors before running
• D. The code is automatically optimized for performance

Answer: (B)

When a programming language is described as interpreted, it indicates that the code is executed sequentially without the need for pre-compilation. This means that the interpreter reads and executes the code directly, line by line, at runtime rather than translating the entire program into machine code before execution. This approach allows for more flexibility and ease of debugging, as changes to the source code can be tested immediately without a separate compilation step. It also often leads to slower execution compared to compiled languages, because each line of code must be interpreted on-the-fly during execution. This characteristic is crucial in development environments where rapid iteration is important. In contrast to this, the other provided options do not accurately describe interpreted languages.
