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 ...

Data Types in C-Programming Language

By
A program usually contains differnt types of data elements and need to store the values being used in program. C-language has different data types for different types of data and can be broadly classified as : 1• Primary Data types 2• Secondary Data types Primary Data Types The primary data type is used for representing a single value only .It is also called simple or fundamental data type. As these are used at primary level in the high level language ,so these are called primary data type .Simple data types has some standard data types.     These are subdivided into 4 categories: 1• Integer data type 2• Floating point data type 3• Character data type 4• Void data type 1• Integer Data Types Generally and integer occupies 2Bytes memory space and its value range  Limited to - 32768 to + 32768 .A signed integer use 1 bit for storing sign and rest 15 bits for number. Range of an unsigned integer is from 0 to 65535 .T...
