What is c programing languege


C Programming Language is one of the most useful and easy to use computer programming languages. 
The person who came up with this C Programming went by the name of Dennis M. Ritchie, and he worked at Bell Telephone Laboratories.
At the time, precisely in 1972, C Programming was meant to help in improving the now widely used UNIX operating system, whose development had begun in 1969. 
 Yes, it did. Its kernel code now began to use fewer lines than it did before when it used the assembly programming language, which is commonly abbreviated as asm.

                 C is a computer programming language. 
That means that you can use C to create lists of instructions for a computer to follow. 
C is one of thousands of programming languages currently in use.
       C has been around for several decades and has won widespread acceptance because it gives programmers maximum control and efficiency. 
C is an easy language to learn.

C is what is called a compiled language. This means that once you write your C program, you must run it through a C compiler to turn your program into an executable that the computer can run (execute). 
The C program is the human-readable form, while the executable that comes out of the compiler is the machine-readable and executable form. 
What this means is that to write and run a C program, you must have access to a C compiler. 
If you are using a UNIX machine (for example, if you are writing CGI scripts in C on your host's UNIX computer, or if you are a student working on a lab's UNIX machine), the C compiler is available for free. 
It is called either "cc" or "gcc" and is available on the command line. 
If you are a student, then the school will likely provide you with a compiler -- find out what the school is using and learn about it. 
If you are working at home on a Windows machine, you are going to need to download a free C compiler or purchase a commercial compiler. 
A widely used commercial compiler is Microsoft's Visual C++ environment (it compiles both C and C++ programs).

Other Early Projects Improved By C-


UNIX was not the only project to be made more efficient by the C Language. 
The Oracle database also benefitted when, in 1983, its initial code that had been written in asm was re-written in the C language.
 The development of the Oracle database had begun in 1977. 

Windows 1.0 :-

Windows 1.0, which was released in 1985, is said to be partially written in C and partially in assembly or asm. The source code is, however, not available to the public. 

The Linus kernel :-

The Linux kernel, which was released in 1992 as a composite part of the GNU operating system, and whose development began in 1991, also uses the C Language. Although some of GNU’s components use Lisp programming languages, it still has others that use the C programming language.Read More
