Which of these computer languages can only be run without modification

The question is not very clear, but if you are asking which computer languages can only be executed without making any changes to the code, then the answer would be compiled languages. Once a compiled language code is translated into machine code, it can be executed directly without modification. Examples of compiled languages include C, C++, Java, and Go.

There isn't a specific computer language that can only be run without modification, as most programming languages require some level of modification to adapt to different platforms or versions. However, some programming languages are considered more portable, meaning they can be executed across different systems with minimal changes. Examples of such languages include Java, Python, and JavaScript. These languages are designed to be platform-independent and can run on various operating systems with relatively few modifications.
