How do you explain the computing environment in c language?

Answer 1

It is not possible to explain the computing environment in terms of a high-level programming language because the language is independent of the machine; it is the machine that defines the computing environment not the language. With high-level languages like C, the exact same source code can be compiled on any machine regardless of its computing environment. Note that the language itself is merely an abstraction; it allows us to express computations in a machine-independent manner.

The implementation of the language is actually defined by the language compiler. Each machine type requires its own independent implementation, although a single compiler implementation can cater for a family of processors sharing a common architecture (such as 32-bit and 64-bit variations of the same architecture). The C language standard defines how computations should be expressed in the language itself, but it is the compiler's job to interpret these expressions such that every machine performs the computations as efficiently as the hardware will allow and produces consistent results regardless of the computing environment.
