Programming Languages

C language:
C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, and therefore it has found lasting use in applications that had formerly been coded in assembly language, including operating systems, as well as various application software for computers ranging from supercomputers to embedded systems.
Scope:
C programming, though not widely used by many, is still one of the "most-sought" skill. Lack of good C programmer nowadays makes it the most sought one.
There are good amount of application of C Skills. One of them is embedded programming. You just can't use any other language for embedded programming other than C /C+, as the systems response time won't be efficient.
Long way to go before C programming dies.
C+ Language:
C+ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C+ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.
Scope:
Where is it used?
Systems programming, telecoms, embedded systems and finance applications.
What systems does it run on?
C+ is supplier-independent, and is supported, for example, by both the Eclipse development platform and - with controversial proprietary extensions that limit portability - by Microsoft's C+/CLI.
