Programming in C

Although C was designed for implementing systemsoftware, it is also widely used for developing portable application software.C is one of the most widely used programming languages of all time and thereare very few computer architectures for which a C compiler does not exist. Chas greatly influenced many other popular programming languages, most notablyC, which began as an extension to C. C is an imperative (procedural) systemsimplementation language. It was designed to be compiled using a relativelystraightforward compiler, to provide low-level access to memory, to providelanguage constructs that map efficiently to machine instructions, and torequire minimal run-time support. C was therefore useful for many applicationsthat had formerly been coded in assembly language.
