Cstandardikirjaston

Cstandardikirjaston, often referred to as the C standard library, is a collection of functions and macros defined by the C programming language standard. It provides essential building blocks for various programming tasks, enabling developers to interact with the operating system, perform input/output operations, manage memory, and manipulate strings and mathematical functions without needing to write low-level code from scratch.

Key components of the C standard library include header files, each providing declarations for a specific set of functions. For instance, stdio.h offers functions for standard input and output like printf and scanf, while stdlib.h contains general utility functions such as memory allocation (malloc, free) and conversion functions. String manipulation is covered by string.h with functions like strcpy and strlen, and math.h provides mathematical operations like sin and cos.

The C standard library is designed to be portable, meaning code written using its functions can typically be compiled and run on different operating systems and architectures with minimal or no modifications. This portability is a cornerstone of C's widespread use in system programming and cross-platform development. Implementations of the C standard library are provided by C compiler vendors as part of their toolchains.
