The C Library (libc) is a standard library in the C programming language that provides a collection of basic functions for performing tasks like input/output operations, string manipulation, memory management, and mathematical computations. It serves as a crucial component for C programs, offering a consistent interface for interacting with the underlying operating system and hardware.
In Linux, the most commonly used C library is glibc (GNU C Library), which is widely adopted across various Unix-like operating systems. libc functions are essential for nearly all C programs, as they handle low-level operations and system calls that are fundamental to program execution. The library is also critical for compatibility, ensuring that C programs can run on different systems with minimal modification.
