C Programming Practice Exam

C programming is a foundational language known for its efficiency, flexibility, and versatility. It is widely used in system programming, embedded systems, application development, and software engineering. C provides low-level access to memory, making it suitable for developing operating systems, device drivers, and performance-critical applications. Skills covered in C programming include understanding basic syntax and semantics, memory management, data types, control structures, functions, pointers, and file handling. Prerequisites typically include a basic understanding of programming concepts, familiarity with algorithms and data structures, and proficiency in problem-solving.
