A criteria-compliant C method which is penned with portability in mind could be compiled for an extremely wide selection of Computer system platforms and working systems with handful of changes to its resource code. The language has grown to be offered on an extremely wide range of platforms, from embedded microcontrollers to supercomputers.
You can find environments in which limits on use of normal C++ language or library characteristics are important, e.g., to stay away from dynamic memory allocation as essential by plane control software specifications.
We do not limit our remark in the Enforcement sections to things we know how to enforce; some remarks are mere needs Which may inspire some Device builder.

These capabilities are in-depth in several requirements for example POSIX and the Single UNIX Specification.
In 2008, the C Specifications Committee revealed a technological report extending the C language[21] to address these problems by furnishing a common common for all implementations to adhere to.
