I/O function in C

2016-02-17T15:49:00.000+05:30

I/O function in C

I/O function used read the input from the keyword and display the output to the screen. C Language have some predefined input and output function and that are listed below

I/O Functions for Single Character:-

It get only one character input and display one character only.

INPUT FUNCTION

getchar( )

getc( )

getch( )

OUTPUT FUNCTION

putchar( )

putc( )

putch( )

I/O Functions for String :-

It get multiple charter like a string can get as Input and also display by strings.

OUTPUT FUNCTION

puts( )

INPUT FUNCTION

gets( )

Scanf Input functions:-

Scanf( ) is a library function that is used for input function. It return value is based on the either input value is correct or not.

Syntax:-

scanf ("Control Strings", &variable name);

Ex:

int a; float b,c;
scanf("%d",&a);
scanf("%f %f", &b,&c);

Printf Output Function:-

printf ( ) is a library function that displays information on screen. It return value is based on the characters of within the brackets and empty space also counted.

Syntax:-

printf ( "Control String", Variable name);

Ex:

int a; float b,c;
printf("%d", a);
printf("%f %f",b,c);

Printf and scanf functions most often Input output (I/O) functions. Both printf and scanf function has return values not null. We cannot define program without I/O.

Data Type in C

2016-02-17T01:26:00.000+05:30

Data Type in C

Define:-

Data type is defining attributes to the variable in C. The main part of C language is Data Type, which is used to allocate memory for variable. Data types are has different types of formats such as int, char, float sting, double and etc.

1. Integer Data type :-

Integer data type represented by "int" => 2 bytes (1 byte = 8 bit).

It can store the value of Whole Number. It can store up to 16 bit block of data. If 16 bits filled then its showing error message only. If you want store more than 16 bit blocks then you can choose other integer data type as "long int". Other formats of integers are following by int, short int, long int, unsigned int

2. Float Data Type:-

Floating data type represented by float => 4 bytes.

Floating Data type is used to calculate fraction decimal Calculation as same as storing information on it. Floating variables are call by %f. They extended formats of float is Double which has 8 byte of data for storage.

3. Character Data Type:-

Character Data type represented by char. Characters are single letter which are used at check box for Y/N question or condition.

char => 1 byte

Data types and Control Strings:-

Control strings are address of Data types. Every data types has separate control string. Control strings are used to get variables value. Every control strings get/put their related values and then give it to the specify variables.

Escape Sequence Function:-

C has another one good escape sequence functions. Those are used to format the output on print screen. You can add basic formats such as more than 2 space, New line, Back Space , Alert and etc. All escape sequence are execute only at output screen. Its written in printf or scanf statements. We can put escape sequence after placing our control string of data type .

Token in C Language

2016-02-17T00:00:00.000+05:30

Token's in C Language

Character Set:-

Set of Characters are referred to as set is group as follows.

1. Letters - A to Z (or) a to z

2. Digits - 0 to 9

3. Special Characters - {. , ; : ' " { }+ - * % / \ ( ) ^ }

4. White spaces - tab [5 space]

Token in C Language :-

The smallest individual unit in the program is called token. Which are defined whole program. Before you writing program we need know about Tokens. The set of tokens are Keywords, Variable, Constant and Operator.

Keyword in Token:-

Keyword is the first part of Token in C language. Keyword is predefined special meanings. Each keyword used separate purpose such as allocating storage for numeric, fractions, characters and strings.

Ex:- int, float, double, char, string

char => 1 byte
int => 2 byte
float => 4 byte
string => 4 byte
double => 8 byte

Variable in Token :-

Variables are user defined Token in C. Variable is a data name that maybe used to store a data value for easy to retrieved. A variable declaration consists data type followed by a list of one or more variables and that are separated by comma's

Syntax:-

<data type> Variable name;

Ex: int a;

Constant in Token:-

A constant is an entity whose value does not change during program execution. Constants allocated once when program started. Much favorable one in Token in C is Constant.

Ex:- int a=10;

Two types of constant and that are

(1) Numeric constant

->Interger
->Real

(2) Character Constant

->Char
->String

Integer Constant:-

It contains sequence of digits that may or may not predefined with a minus sign. Mostly we used integer constant. Integer constant is easy to calculated values and its store smaller amount of storage.

Ex: 14, -12

Real Constant:-

It can be represent into decimal. Fractional calculations are done by real constant only. Real constant values are represent by float keywords in Token in C.

Ex: 12.43

Character Constant:-

It contain single character enclose with in a pair of single quotes. Character constants are used for specify some character fixed. Which is used for Yes or No questions such ah input as Y/N.

Ex: 'k' , 'X'

String Constant:-

A string Constant is a group of character enclosed in double quotation. These are characters or any special characters. Most often use string constant. We use maximum input from users by string only for storing user's detail such as user name, password. name and their detail.

Ex: "Welcome", "1928"

char[10] = "Welcome";

String constant Mostly used in program. Best way of explian some important msg for users. String Constant is best one at Token in C

C Language

2016-02-16T16:44:00.000+05:30

Introduction to C language

C Language is general purpose programming language. It has many desirable qualities of modern programming languages such as Portability, Fle
xibility and Efficiency

Portability means which is support all operating system and Compilers. Without any modification you can run all type of compiler.

Primary strength of C Language is More efficient. This is due to the fact that it has many low level fractions. It also has a ability to build complex program out of simple elements.

**Development of C Language :-**

(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 Language :-

* 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 Language:-

C Language can be 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.

C Language 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 in C language.

C Program

Introduction:-

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

Portability of a program mean transferring a program to another computer with minimum changes one.
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:-

1960 AL Gol to international committee
1967 BCPL - Martin Richard. (BCPL - Basic Combined Programming Language)
1970 B - Ken Thompson.
1972 C - Dennis Ritchie
1978 K & NC - Kenning ham & Dennis Ritchie.
1989 ANSI C - ANSI Committee
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

TCP/IP Layers & Protocols

2014-03-15T22:56:00.002+05:30

TCP/IP :-

TCP/IP defines a large collection of protocols that allow computers to communicate. TCP/IP defines the details of each of these protocols inside document called Request For Comments(RFCs). TCP/IP Classifies the various protocols into different categories.

TCP/IP Application Layer:-

The most popular TCP/IP application today is the web browser. Many major software vendors either have already changed or are changing their software to support access from a web browser.

Taking a closer look, this example uses two TCP/IP application layer protocols. First the request for th file and the actual trasfer of the file are performed according to the Hypertext Transfer Protocol(HTTP).

The TCP/IP Transport Layer:-

The TCP/IP application layer includes a relatively large number of protocols, with HTTP being only one of those. the TCP/IP transport layer consists of two main protocol options

Transmission Control Protocol(TCP)
User Control Protocol(UDP).

TCP/IP needs a mechanism to guarantee delivery of data acrss a network. TCP provides that feature by using acknowledgments. The HTTP software asks for Tcp to reliably deliver the HTTP get request. TCP sends the HTTP data from Browser to Server, and the data arrives successfully. TCP software acknowledges receipt of the data and also gives the HTTP get request to the web server software.
