About HTML5
HTML is the standard markup language for creating Web pages.
* With HTML you can create your own Web site.
* This tutorial teaches you everything about HTML.
* HTML is easy to learn - You will enjoy it.
HTML Introduction
What is HTML?
HTML stands for Hyper Text Markup Language.
HTML describes the structure of Web pages using markup.
HTML elements are the building blocks of HTML pages.
HTML elements are represented by tags.
HTML tags label pieces of content such as "heading", "paragraph", "table", and so on
Browsers do not display the HTML tags, but use them to render the content of the page
A Simple HTML Document
Example Explained
* The < !DOCTYPE html > declaration defines this document to be HTML5* The < html > element is the root element of an HTML page
* The < head > element contains meta information about the document
* The < title > element specifies a title for the document
* The < body > element contains the visible page content
* The < h1 > element defines a large heading
* The < p > element defines a paragraph
HTML Tags
HTML tags are element names surrounded by angle brackets:< tagname >content goes here...< /tagname >
* HTML tags normally come in pairs like < p > and < /p >
* The first tag in a pair is the start tag, the second tag is the end tag
* The end tag is written like the start tag, but with a forward slash inserted before the tag name
Tip: The start tag is also called the opening tag, and the end tag the closing tag.
HTML Text Formatting
HTML Bold < b > and Storng < strong > Elements
* This text is strong and* This Text is Bold
HTML Italic < i > and Emphasized < em > Elements
* This Text is in Italic and* This text is emphasized
HTML Small < small > Element
* HTML Small FormattingHTML Marked < mark > Element
* HTML Marked Formatting
HTML Element < del > Element
* My favorite color is HTML < ins > Element
* My favorite color is red.HTML < sub > Element
* This is subscripted text.HTML < sup > Element
* This is superscripted text.HTML Quotation and Citation Elements
Quotation
Here is a quote from WWF's website: For 50 years, WWF has been protecting the future of nature. The world's leading conservation organization, WWF works in 100 countries and is supported by 1.2 million members in the United States and close to 5 million globally.HTML < q > for Short Quotations
WWF's goal is to:Build a future where people live in harmony with nature.
HTML Images
HTML images are defined with the < img > tag.
The source file (src), alternative text (alt), width, and height are provided as attributes:
HTML Links
HTML links are defined with the < a > tag:

Introduction to 'C' Programming Language.
ANSI: American National Standard Institute.
ISO: International Standards Organization.
History
of ANSI C.
C: C is a programming language, it’s used to communication with
computer.
Developer of C: C is developed by Danish Ritchie.
·
C is portable, efficient and fast and flexible.
·
Stdio.h: It look for the stdio.h file and
efficiently copy-pastes it in the place of this #include statements.
This file contains so called functions proto types of functions such as printf(),
scanf(),… so that compiler known’s what are their parameters and
return value.
·
Stdio.h
meaning: Standard Input/Output and h is
header.
·
Conio.h: It is a C header file used mostly by MS-DOS compilers
to provide console input/output. It is not part of C standard
library or ISO C, nor is it defined by POSIX.
·
conio.h
meaning:
Characteristics.
1) Portable: C
program written for one computer can run one any other computer with little
modification.
2) Structured programming language: includes functions & blocks modules structure.
3) Efficient & Fast: This
is because of variety of data types & operators.
4) Another Important Feature: is its quality to extend itself C Program is
a collection of functions &we can add our functions as per-requirements.
·
Two types of functions.
i) User
defined: created by uses.
ii) Library:
Inbuilt in system.
·
Structure of C
Programming with example.
i)
Basic syntax for writing C
Program.

Procedure to create C Program.
1) Install Turbo
C
2) Open Turbo
C
3) New
File
4) Write
a program & press F2 or Save
5) Compile
to press Compiler or Alt+F9
6) Run
or press Ctrl+F9
Execution of C Program.
Steps of execution.
1) Creating
the program
2) Compiling
the program
3) Linking
the program
4) Run(execute)
the program
An operating executes the program it
is a program that controls the entire operation of a computer system. All
outputs are connected with OS.
A programming language is used to …
i) A
programming language is used to help the processing of some types of data
(character, numbers & strings) to generate output, which is known as program.
ii) The
processing of data is done using certain instruction set which is known as
program.
iii) These
instruction are created using certain symbols & words according some rigid
rules known as syntax rules.
Character Set.
1) The
characters can be used to generate numbers, words & expressions depend on
the computer on which it Runs.
2) The
character set is different for computers, minicomps, microcomps, etc.
3) The
characters in C are grouped of
§ Letters
§ Digits
§ Special Characters
§ White Space
4) White
space is ignored by compiler during execution.
5) White
space is allowed during use of string.
Trigraph Sequence .
i) Some
non English keyboards do not support some characters.
ii) If
we want to enter certain characters that can not available on keyboard
they Trigraph Sequence is used.
iii) Syntax
for Trigraph Sequence is
·
First two question mark
·
Third is character
iv) For
Example if # is not available on keyboard, we can enter it using Trigraph of
??=
-# number sign

Variables.
1) Variable
is used to store data values.
2) It’s
value can change throughout program.
Rules for variable Names
1) It
begins with letter or underscore.
2) Space
is not allowed.
3) It
should not be keyword.
4) Length
is up to 31 characters.
Syntax:
Data type V1,V2,…Vn;
Declaration of variable:
Int a;
It tells compiles about
1) Name
of variable.
2) Which
type of data it holds.
