C standard library

The C standard library, sometimes referred to as libc,1 is the standard library for the C programming language, as specified in the ISO C standard.2 Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it.3 Since ANSI C was adopted by the International Organization for Standardization,4 the C standard library is also called the ISO C library.5

The C standard library provides macros, type definitions and functions for tasks such as string manipulation, mathematical computation, input/output processing, memory management, and input/output.
