Get Started Basic HTML TAGS

Requirements to study HTML

A text editor
A Web browser
Where you can type the code

Open a text editor like notepad and type the code and save the file as somename.html The .html is very important

<HTML> - Opening Tag of html Page

</HTML> - Closing tag of a html page

Titles of your webpages

You can set the titles appearing on web browsers using <title> tag .It can be used as

<title> Type The Title You Want To Appear </title>

Heading Of a Webpage

You can use <h1> , <h2> , <h3> , <h4> , <h5> , <h6> Tags for headings
These are the results and respective codes of Heading tags

This is a H1 heading Code - <h1> This is a H1 heading</h1>

This is a H2 heading code - <h2> This is a H2 heading</h2>

This is a H3 heading code <h3> This is a H3 heading</h3>

This is a H4 heading code <h4> This is a H4 heading</h4>

This is a H5 heading code <h5> This is a H5 heading</h5>

This is a H6 heading code <h6> This is a H6 heading</h6>

Links In a Webpage
<a href="Type The target of the web address here"> The Text To be Linked Here </a>
The target of your web page may type after href attribute . See this example

Result digipool
Code -- <a href="http://digipool.blogspot.com/">digipool </a>

In the above example http://digipool.blogspot.com/ is the target address and digipool is the text to be linked.

PHP Program Syntax

We can use PHP code between HTML codes .The PHP code must begin with <?php and end with ?> . PHP may insert between HTML tags but you need to specify it . Using this <?php ?> we can separate PHP codes from HTML tags. At executing time server will avoid html tags from execution of the program. If you need to print html tags you can use

Echo " <html Tag here>";

Eg :

<html>
<p><b> This is a html page contain PHP codes </b></>
<img src="somepicture's path"></img>
PHP code begins here

<?php
printf("This is a block of PHP codes");
?>

<b>PHP code ends</b>
</html>

Printf is used to print some charecters in a html page

Create Database in PHP Mysql

It is very easy to create database in xampp.You can create Databases By directly executing the SQL query Or using PHP Myadmin

Using PHP Myadmin
Goto http://localhost/phpmyadmin/
Type the name of the database and click on create

Type the name of table and Number of fields click on GO

Type the name of field , type , length and click on GO

Now the database with table and fields is created

You may create database by executing the SQL query directly .

Running a PHP Script

PHP is the simplest language among server side programming languages.There is no need of virtual machines to execute php code in clients computer.It is totally different from other languages like C , C++ , VB etc.To run a PHP script we need to install a package Xampp Or Wamp.

Download And Install Xampp

After installing the package Type your PHP code in some text editor like notepad
Then save the program as somename.php to Htdocs folder ( In windows its default path is C:\xampp\htdocs\ )
Then open Browser and goto the address http://localhost/Program_name.php
Now the output will be displayed if their is no errors.
You may create folders in htdocs if you want to access the folder change the path to
http://localhost/Foldername/Filename.php

C Program To Add Two Matrices Using Function

How to add 2 matrix in c

Algorithm for adding 2 matrices

1) Check the sizes of two matrices math A (m×n) and math B (u X v): if m = u and n = u then display a message matrix addition is possible . Otherwise print matrix not possible Exit .

2) Create a new square matrix of size m×n.

3) For each element in A find the element at the same position at B and add the two values.

Main variables

m1,m2 = 2 matrices 2d arrays

n = Result matrix

i,j = Loop controllers

r,r1,c,c1 = Row and Column

Program

#include<stdio.h>

main()

{

int i,j,r,c,r1,c1,m1[50][50],m2[50][50],n[50][50];

void matsum(int[50][50],int,int);

printf("Enter the number of rows and column of 1st matrix\n");

scanf("%d %d",&r,&c);

printf("Enter the elements of matrix 1");

for(i=0;i<r;i++)

{

for(j=0;j<c;j++)

{

scanf("%d",&m1[i][j]);

}

printf("Enter the number of rows and column of 2nd matrix\n");

scanf("%d %d",&r1,&c1);

printf("Enter the elements of matrix 2");

for(i=0;i<r1;i++)

{

for(j=0;j<c1;j++)

{

scanf("%d",&m2[i][j]);

}

if((r1==r)&&(c1==c))

{

for(i=0;i<r;i++)

for(j=0;j<c1;j++)

{

n[i][j]=0;

n[i][j]=m1[i][j]+m2[i][j];

}

matsum(n,r,c1);

}

else

printf("Matrix addition not possible\n");

}

void matsum(int x[50][50],int y,int z)

{

int i,j;

printf("Sum of the matrices is \n");

for(i=0;i<y;i++)

{

for(j=0;j<z;j++)

{

printf("%d",x[i][j]);

printf("\t");

}

printf("\n");

}}

Output

Enter the number of rows and column of 1st matrix

2 2

Enter the elements of matrix

1 1

Enter the number of rows and column of 2nd matrix

An introduction to PHP - Some Basic HTML tags

<a>
The tag <a> is used for define html links.
Eg : <a href="http://123codings.blogspot.com/">My Blog</a>
http://123codings.blogspot.com/ is the link address ( target address ).My Blog is the text.
Result - My Blog

<b>
The HTML tag <b> stands for Bold. It gives a bold text.
Eg <b> 123codings </b>
Ordinary text 123codings
Bold text 123codings

<br>
The tag <br> is used for a new line it dont have an end tag like </a> .
Eg : 1st line<br>2nd line
Result :
1st line
2nd line

<i>
The tag <i> is used for italics text.

Ordinary text 123codings

Italics text 123codings

<img>

The <img> tag is used to insert an image on HTML pages.
src = full address / path of image

Eg : <img src="http://someaddress/somepicturename.image's extension"></img>

<img src="http://3.bp.blogspot.com/-gSd4vVj7XE/ToE9IN_jLrI/AAAAAAAABuY/Df_MAYwsokY/s1600/123codings.akg.jpg"></img>

C Program To Implement Bubble Sort

Bubble Sort

The bubble sort may be notoriously slow, but it's concept is simple in the all sorting
algorithms, so that reason is a good beginning for our exploration of sorting
techniques.

Algorithm

1. Compare each pair of adjacent elements from the beginning of an array
2. If they are in reversed order, swap them.
3. If at least one swap has been done, repeat steps 1&2

Program

#include<stdio.h>
main()
{
int a[100],i,n,j,tem=0;
printf("enter the limit");
scanf("%d",&n);
printf("enter the numbers");
for(i=0;i<n;i++)
scanf("%d",&a[i]);
for(i=0;i<n-1;i++)
for(j=0;j<n-1-i;j++)
if(a[j]>a[j+1])
{
tem=a[j];
a[j]=a[j+1];
a[j+1]=tem;
}
printf("sorted array");
for(j=0;j<n;j++)
printf("%d\n",a[j]);
}

Output

enter the limit 5
enter numbers 2 1 3 5 4
sorted array is
1
2
3
4
5
