Create First Program of PHP,How to create first program using PHP



1) Download PHP Software Tools:-
    1.1) XAMPP Server:-   It provides Apache Web Server, MYSQL Database Server, PHP Script, and Pearl Script. It is common for all operating systems (Windows, Linux, MAC, Solaris, Unix, Android)
   X----> ANY
   A ---->  Apache
   M ----> MYSQL
   P-----> Pearl
   P------> PHP
1.2) WAMP, LAMP, MAMP is the other software tools of PHP
     WAMP is specially for  Windows (W--Windows,A--> Apache,M--> MYSQL,P-->PHP)
     LAMP  is specially for LINUX   (L--> LINUX,A---> Apache,M--> MYSQL,P-->PHP)
     MAMP is specially for MAC      (M-->MAC,A--> Apache,M-->MYSQL,P---> PHP)
download xampp from this link
https://www.apachefriends.org/download.html
2)  Open XAMPP Control Panel:-
      Click on the Desktop xampp icon  and click on the apache start button
      if not present in desktop icon then go c://xampp/xampp-control.exe
3)  open notepad and create .php file
under c:/xampp/htdocs/foldername (create new folder first time and save file)
<?php
echo "hello world";
?>
save php file using .php extension
4)   open browser and type localhost/folder name  
Internal Working of PHP:-
When we click on a file or direct URL from the browser address bar then it will create HttpRequest Object and Send to Apache Web Server.
Apache Web Server will get requests, process the requested file, generate a result, convert the result into HTML form and send it back to the browser using HttpResponse Object.
Url locate Server Address using localhost or remote server.
for example, http://localhost/php11/Demo1.php is a localhost URL for testing purposes or a desktop-based web application.
for example http://shivaconceptsolution.com/digital/  It is the remote URL because shivaconceptsolution.com is a domain name that points to a remote server 
Example of PHP:-
Create Hello World Program?
<?php
print("hello world");
?>
Create Welcome Program?
<html>
<head>
<body bgcolor='cyan'>
<h1>Second Program of PHP</h1>
<hr>
<?php
print("PHP IS A SCRIPT<br>");
print("WELCOME IN SCS<br>");
print("Hello");
?>
</body>
</html>
Create Addition Program:-
<?php
$a=1555656777;
$b=2345555555;
$c=$a+$b;
print($c);
?>
ASSIGNMENT:-
1)  WAP to swap two numbers?
2)  WAP to calculate simple interest?
<?php
$p=15000;
$r=2.2;
$t=3;
$si = ($p*$r*$t)/100;
echo "Result is ".$si;
?>
3) WAP to calculate the area of triangle or rectangle?

DSA in C# | Data Structure and Algorithm using C#

  DSA in C# |  Data Structure and Algorithm using C#: Lecture 1: Introduction to Data Structures and Algorithms (1 Hour) 1.1 What are Data Structures? Data Structures are ways to store and organize data so it can be used efficiently. Think of data structures as containers that hold data in a specific format. Types of Data Structures: Primitive Data Structures : These are basic structures built into the language. Example: int , float , char , bool in C#. Example : csharp int age = 25;  // 'age' stores an integer value. bool isStudent = true;  // 'isStudent' stores a boolean value. Non-Primitive Data Structures : These are more complex and are built using primitive types. They are divided into: Linear : Arrays, Lists, Queues, Stacks (data is arranged in a sequence). Non-Linear : Trees, Graphs (data is connected in more complex ways). Example : // Array is a simple linear data structure int[] number...
