Which one of the following languages is interpreter?

Programming languages are generally classified as either compiled or interpreted based on how the code is executed. Python is an interpreted language, meaning its source code is executed line-by-line by an interpreter (typically via bytecode and a virtual machine) rather than being translated into machine code before execution. This makes it highly portable and easier to debug.

• FORTRAN: A compiled language primarily used for scientific and numerical computing.
• Pascal: A compiled language designed for teaching structured programming and data structuring.
• C++: A powerful compiled language that provides low-level memory manipulation and is widely used for system software and game development.

In compiled languages, a compiler translates the entire program into machine code at once, whereas in interpreted languages like Python, the translation happens during runtime.
