About

It is specified in the ISO/IEC Standard 9899, commonly known as the C89, C90, or C11 standard. The C standard library is included with most C compilers and is an essential part of C programming. It provides a wide range of functions that allow programmers to write efficient and portable code. These functions are organized into several categories, including input/output (stdio. h), string handling (string. h), memory management (stdlib. h), mathematical functions (math. h), and many others. The C standard library is designed to be small and efficient, with a focus on performance. It is also designed to be portable, meaning that programs written using the library can be compiled and run on different platforms without modification. This portability is achieved through the use of standard types, such as int and char, and standard functions, which have consistent behavior across different compilers and operating systems. Although the C standard library provides a wide range of functionality, it does not cover every possible programming task. In some cases, additional libraries, such as the POSIX library for operating system functionality or the Curses library for terminal manipulation, may be needed. However, the C standard library forms the foundation for most C programs and provides a solid base for developers to build upon. Overall, the C standard library is a vital component of C programming, providing a set of functions and macros that facilitate common programming tasks. It is widely used and supported, making it an essential reference for C programmers.
