Introduction of C program

C Program

Introduction:-

                     C is general purpose programming language. It has many desirable qualities of modern programming languages like portability flexibility and efficiency

1. Portability of a program mean transferring a program to another computer with minimum changes one.
2. c has the primary strength of being efficient. This is due to the fact that it has many low level fractions. It also has a ability to build complex programmes out of simple elements.

Development of C:-

1. 1960 AL Gol to international committee
2. 1967 BCPL - Martin Richard.  (BCPL - Basic Combined Programming Language)
3. 1970 B - Ken Thompson.
4. 1972 C - Dennis Ritchie 
5. 1978 K & NC - Kenning ham & Dennis Ritchie.
6. 1989 ANSI C - ANSI Committee
7. 1990 ANSI/ISO C - ISO Committee

Features Of C:-

• C combines the capabilities of an assembly language as well of feature of high level language.
• Highly portability
• System software development
• More built in functions
• Case sensitive
• Powerful & flexible language.

C Program:-

           C program can be thought of a collection of decentralized com-putative structures called functions. It these functions are logically group and put together then it is referred as library. Thus c program can be defined as a collection of function supported by standard 'C' library. 

Program Structure:-

stdio.h = Standard input / output

conio.h = Console input / output

{ }= starting loop and ending loop

main() = main() is a special funtion used to inform the compiler that the program starts logically. Every program must have exactly one main function.
