The correct answer is: E. None of the above.
A functional language is a programming language that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in state.
A machine language is a low-level programming language that is directly executed by a computer’s central processing unit (CPU). Each instruction in a machine language program is a sequence of bits that tells the CPU what to do. Machine languages are specific to the type of CPU they are designed for, and they are very difficult for humans to read and write.
An application language is a high-level programming language that is designed to be used for a specific application. Application languages are typically easier to learn and use than machine languages, and they are often used to develop software applications.
A low-level language is a programming language that is closer to the machine code that a computer understands. Low-level languages are typically more difficult to learn and use than high-level languages, but they can be more efficient.
A high-level language is a programming language that is designed to be easier for humans to read and write. High-level languages are typically less efficient than low-level languages, but they are easier to learn and use.
