C is a file extension for a C  or C++  source code file format used by Borland C++ , CodeWarrior and Microsoft Visual C++ software development programs.

C is a structured, procedural programming language that has been widely used both for operating systems and applications and that has had a wide following in the academic community. Many versions of Unix-based operating systems are written in C. C has been standardized as part of the Portable Operating System Interface (POSIX).

With the increasing popularity of object-oriented programming, C is being rapidly replaced as the most popular programming language by C++ . C++ is a superset of the C language that uses an entirely different set of programming concepts.
