c programming overview

1. C programming overview

C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972.
In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard.
The UNIX operating system, the C compiler, and essentially all UNIX applications programs have been written in C. The C has now become a widely used professional language for various reasons.
o      Easy to learn
o      Structured language
o      It produces efficient programs.
o      It can handle low-level activities.
o      It can be compiled on a variety of computer platforms.
Facts about C 
1.       C was invented to write an operating system called UNIX.
2.       C is a successor of B language which was introduced around 1970
3.       The language was formalized in 1988 by the American National Standard Institute (ANSI).
4.       The UNIX OS was totally written in C by 1973.
5.       Today C is the most widely used and popular System Programming Language.
6.       Most of the state-of-the-art software have been implemented using C.
7.       Today's most popular Linux OS and RBDMS MySQL have been written in C.
Why to use C ?
C was initially used for system development work, in particular the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as code written in assembly language. Some examples of the use of C might be
o        Operating Systems
o        Language Compilers
o        Assemblers
o        Text Editors
o        Print Spoolers
o        Network Drivers
o        Modern Programs
o        Databases
o        Language Interpreters
o        Utilities

c programming basic syntax

BASIC SYNTAX Tokens in C A C program consists of various tokens and a token is either a keyword, an identifier, a constant, a string literal, or a symbol. For example, the following C statement consists of five tokens: printf("Hello, World! \n"); The individual tokens are: printf ( "Hello, World! \n" ) ; Semicolons In a C program, the semicolon is a statement terminator. That is, each individual statement must be ended with a semicolon. It indicates the end of one logical entity. Given below are two different statements: printf("Hello, World! \n"); return 0; Comments Comments are like helping text in your C program and they are ignored by the compiler. They start with /* and terminate with the characters */ as shown below: /* my first program in C */ You cannot have comments within comments and they do not occur within a string or character literals. Identifiers A C iden...
