Which kind of languages are C, C++ and Java?

C, C++, and Java are all classified as compiled languages. In this model, the human-readable source code is processed by a compiler program before execution. The compiler translates the source code into a lower-level representation. For C and C++, this is typically native machine code specific to the target processor. For Java, the compiler generates platform-independent bytecode, which is then executed by the Java Virtual Machine (JVM). Despite the intermediate step for Java, the essential pre-execution translation by a compiler is the common, defining characteristic.

A. Markup languages like HTML are used for document structuring and presentation, not for creating the logic of an application.

C. Interpreted languages are processed line-by-line at runtime. C, C++, and Java all require a distinct, ahead-of-time compilation step.

D. Machine code is the result of compiling languages like C and C++; it is the target language, not the source language category.
