C Standard Library - The C Standard Library in Other Languages

The C Standard Library in Other Languages

Some languages include the functionality of the standard C library in their own libraries. The library may be adapted to better suit the language's structure, but the operation semantics are kept similar. The C++ language, for example, includes the functionality of the C standard library in the namespace std (e.g., std::printf, std::atoi, std::feof), in header files with similar names to the C ones (cstdio, cmath, cstdlib, etc.). Other languages that take similar approaches are D and the main implementation of Python known as CPython. In the latter, for example, the built-in file objects are defined as "implemented using C's stdio package", so that the available operations (open, read, write, etc.) are expected to have the same behavior as the corresponding C functions.
