C-LIBRARIES

By

The C programming language uses libraries as its primary method of extension. In C , a library is a set of functions contained within a single "archive " file . Each library typically has a header life , which contains the prototypes of the functions contained within the library that may be used by a program , and declarations of special data types and macro symbols used with these functions .        

      The most common C library is the C standard library , which is specified by  the ISO and ANSI C standards and comes functions with every C implementation.
    Another common set of C library functions are those used by applications specifically targeted for Unix like systems , especially functions which provide an interface to the kernel.
      Libraries are often written in C because C compilers generate efficient object code ; programmers then create interfaces to the library so that the routines can be used from higher-level languages like Java , Perl , and Python.

List of C language library:

1• assert.h
2• ctype.h
3• errno.h
4• float.h
5• limits.h
6• locale.h
7• math.h
8• setjmp.h
9• signal.h
10• stdarg.h
11• stddef.h
12• stdio.h
13• stdlib.h
14• string.h
15• time.h

C-Operators

By
An operator is a symbol that operates on a certain data types and produce the output as the result of the operation. Category of Operators • Unary Operator An unary operator is an operator which operates on one operand that is it operates on itself.            Operand1 operator Here Operand1 may be a variable , a constant or an expression etc.    For example: -b , ~a , x+1 etc. • Binary Operator A binary operator is an operator which operates on two operands. Operand1 operator Operand2 Here Operand1 and Operand2 maybe a variable, a constant or an expression etc. and Operator must be either arithmetic type or relational type or logical type etc.    For example: a+b , a && b , etc. • Ternary Operator A ternary operator is an operator which operates on 3 operands. Operand1 o perator Operand2 operator Operand3   Here Operand1 , Operand 2 , Operand3 may be a variable ...

Introduction to Programming language C

By
Dennis Ritchie ( US) designed C programming language in 1972 at "AT & T's Bell laboratories". C has been often termed as " M iddle Leve l Language " . Programs written in C are very efficient and fast. C is a general purpose structured powerful language. Features at a Glance: • C is highly portable language .This means that a C program written for one system can be run on another system with little or no modifications. • C's another striking feature is its ability to extend itself. We can add our own functions to the C library . • Writing a C program with user defined makes program more simple and easy to understand . • C - language has more data types ( except boolean operators ), operators and can take more variables than other languages. • C - language is a structured programming language that is  it has different modules and blocks . • C - language is used to develop graphics software . 2D and 3D graphics are also implement...
