What is a language processor primarily used for?

A language processor is primarily designed to convert source programs written in a high-level programming language into a format that can be understood by a machine, specifically instruction codes for a computer's processor. This involves several steps, including lexical analysis, syntax analysis, semantic analysis, and code generation or optimization, all aimed at transforming human-readable code into machine language or intermediate code that can be executed by the hardware.

The correct answer accurately describes the core function of a language processor, which is essential for software development. This process allows programmers to write code in languages that are more understandable and manageable, enabling the creation of complex software applications.

The other options involve different functionalities that do not align with the primary purpose of a language processor. Detecting system failures pertains to hardware monitoring and management, processing fuzzy data is related to artificial intelligence and specialized data handling rather than programming language conversion, and creating a linked list pertains to data structure manipulation which can be part of programming but isn't the fundamental role of a language processor.
