The programming language often used for system programming and embedded systems is C. C is a high-performance language that provides low-level access to memory and system resources, making it ideally suited for developing operating systems, compilers, and embedded applications. Its efficiency and portability enable programmers to write code that can run on various hardware architectures with minimal modifications. Additionally, C's extensive libraries and tools have established it as a foundational programming language widely taught in computer science education and utilized in software engineering.
