C standard library

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

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.
