Programmers have often described C as “an abstract high-level language” or as a “mid-level language.” This is not because of a weakness in its software strength, but because of its ability to access substandard system functions. In fact, the C language was specifically designed to realize the programming code of UNIX. The C code can execute as quickly as the assembly script.
In 1969 Ken Thompson created BCPL (Basic Combined Programming Language) by Richard Martin. Ken used PHP and the assembly language to produce the first versions of the Unix operating system. PML and B are two languages that do not contain patterns, so that the variables are simply words in memory.
Later Dennis Ritchie of Bell Labs in 1972 converted P to C by preserving most of the B language commands and wrote the first translator. This was implemented on December 11, 1972. At first it was used to rewrite the script for the UNIX operating system, and later on the UNIX system and its tools and C language evolved simultaneously.
In 1978 Kernighan and Richie wrote a book called ‘The C Programming Language’ which became a definition of this language nearly a decade ago.
At the beginning of 1983, the American National Standards Organization Committee (ANSI) x3j11 requested standardize the C language. Standardized C was adopted (called ANSI C) in 1988. Although it was not imposed on any programmer, it was widely accepted, and it is not economically wise for any system programmer (or writer translators) not to adhere to the standard.
Uses of C language
C is used in many programming systems. Some of them include:
Translators and interpreters of programming languages
Programming digital signal processing applications
Database systems programming
Interpreters are available
The UNIX operating system features a C compiler. If a UNIX system is available to the student, they can start directly writing the commands and translating them using the examples and exercises provided in this course. For personal computers, Microsoft C for IBM or Borland C are the two most popular programming environments. There are a number of free C command converting programs online to install on a computer that one can use as well.
C ++ is now popular with C in the programming world. Although Si stays for a very long time. This is due to several factors, the most important of which is that C ++ although it inherited most of the commands from C, but it incorporated several new concepts
It forms the basis for the topic of Object-Oriented Programming. It is better to know C to learn C ++, but there are many advocates of the theory that calls for one to abandon the habits of procedural programming in order to learn the topic of OOP programming.
Programs that have graphical interfaces based on the C ++ language are more popular, but they consume a large portion of memory and secondary storage media (disks). They depend on complex software libraries that are not suitable for building simple programs to be executed on smaller systems. C language is a better choice when writing Hardware drivers, embedded system software and software utilities.
