Although originally designed as a systems programming language, C has proved to be a powerful and flexible language that can be used for a variety of applications, from business programs to engineering. C is a particularly popular language for personal puter programmers because it is relatively smallit requires less memory than other languages.The first major program written in C was the UNIX operating system。 and for many years, C was considered to be inextricably linked with UNIX. Now, however, C is am important language independent of UNIX. Although it is a highlevel languages, C is much closer to assembly language than are most other highlevel languages. This closeness to the underlying machine language allows C programmers to write very efficient code. The howlevel nature of C, however, can make the language difficult to use for some types of applications.Now let’s take an overview of the C programming language, both historically and technically and technically.As a generalpurpose programming language, C has been closely associated with UNIX system where it was developed, since both the system and most of the applications that run on it are written in C. The language , however, is not tied to any one operating system or machine。 and although it has been called a “system programming language” because it is useful for writing pilers and operating systems, it has been used equally well to write major programs in various fields.Many of the important ideas stem from the language BCPL, developed by Martin Richards. The influence of BCPL on C proceeded indirectly through the language B, which was written by Ken Tompson in 1970 for the first UNIX system on the DECPDP7.BCPL and B are “typeless” languages. By contrast, C provides a variety of data types. The fundamental types are characters, and integers and floating point numbers of several sizes. Additionally, there is a hierarchy of derived data types created with pointers, arrays, structures, and unions. Expressions are formed from operands。 any expression, including an assignment or a function call, can be a statement. Pointers provide for machineindependent address arithmetic. C provides the fundamental controlflow constructions required for wellstructured programs: statement grouping, decision making (ifelse) , selecting one of a set of possible cases (switch), looping with the termination test at the top (while, for) or at the bottom (do), and early loop exit (break).Functions may return values of basic type, structures, unions, or pointers. Any function may be called recursively. Local variables are typically “automatic”, or created anew with each invocation. Function definitions may not be nested but variables may be declared in a blockstructured fashion. The functions of a C program may exist in separate source files that are piled individually. Variables may be internal to a function, external but known only within a single source files, or visible to the entire program.A preprocessing step performs macro substitution on program text, inclusion of other source file, and conditional pilation. C is a relatively lowlevel language, meaning that C deals with the same sort of objects that most puters do, namely characters, numbers, and addresses. These may be bined and moved about with the arithmetic and logical operators implemented by real machines.C provides no operations to deal directly with poseite objects such as character strings, sets, lists, or arrays. There are no operations that manipulate an entire any storage allocation facility other than static definition and the stack discipline provided by the local variables of functions。 there are no heap or garbage collection . Finally, C itself provides no input/output facilities。 there are no Read or Write statements, and no builtin file access methods. All of these higherlevel mechanisms must be provided by explicitlycalled functions. Most C implementations have included a reasonably standard collection of such functions.Similarly, C offers only straightforward, singlethread control flow: tests, loops, grouping, and subprograms, but not multiprogramming, parallel operations, synchronization, or coroutines.Although the absence of some of these features may seem like a grave deficiency, keeping the language down to modest size has real benefits. Since C is relatively small, it can be described in a small space, and learned quickly. A programmer can reasonably expect to know and understand and indeed regularly use the entire language.In 1983, the American National Standard Institute (ANSI) established a mittee to provide a modern, prehensive definition of C. The resulting definition, the ANSI standard, or “ANSI C”, was pleted late in 1988. Most of the features of the standard are alread
