What types of applications you can build in C#.NET ?

C#.NET language can be used to develop four types of applications, these are:

Console applications

Windows applications

ASP.NET Web applications

Web services

Console applications: A console application runs in a console window (ie.MS DOS) which provides simple text-based output.
Windows applications: A Windows application runs on a computer desktop. Windows applications such as MS-Word and Excel, Calculator, Paint etc are example of windows application.
ASP.NET applications: ASP.NET applications are developed to run on a web server which is accessible through browsers. ASP.NET technology facilitates the budding of web applications quickly and easily. Dynamic websites like http://www.microsoft.com are good example of ASP.NET applications.
Web services:Web services are complex applications that can provide services such as current weather update, product stock status, converts the temperature from Fahrenheit to Celsius and many more.

What is a namespace in programming language?

A namespace is a framework for their identifiers (class, methods).
Namespace provide a way of grouping the names that are assigned to elements (class, methods) in a software application so that they don’t conflict with other class, methods names.
Namespaces are heavily used in C# & other OOP language & all .NET Framework classes are organized in namespaces, to be used more clearly and to avoid confusion.

What is the .NET Framework ?

The (dot net) .NET Framework is a software framework developed by Microsoft. It has a huge number of class libraries which provides:

User interface, which is used to design for software interface,
Database connectivity, used to connect with database
Cryptography, used to ensure software security,
Web application development,
Network communications and many more facilities on software development.

C#, VB, J# etc are the programming language used by software developer with the combination of .NET framework to developed software application.

The software applications developed with the dot net framework mainly runs on Microsoft Windows OS.

The most important components of the .NET framework are:

CLR (Common Language Runtime), which allows us to compile and execute program.
FCL (Framework Class Library), which has a large number of predefined types or classes to use in software development.

What are the difference between echo() and print() in PHP ?

To better understand the difference, you have to know the syntax with example of echo() and print(). Syntax of echo() :

void echo ( string $arg1 [, string $... ] )

Example of echo():

<?php

    echo ("The quick brown fox.");

    echo "The quick brown fox.";

    $dept_name="HR";

    echo "My department name is :$dept_name";

    echo"<p>

    Another message 1 Another message 2

    Another message 3

    </p>";

    ?>

Syntax of print()

int print ( string $arg )

Example of print():

    <?php

    print("The quick brown fox.");

    print "The quick brown fox.";

    $dept_name="HR";

    print "My department name is :$dept_name";

    print"<p>

    Another message 1 Another message 2

    Another message 3

    </p>";

    ?>

echo() is used to output one or more strings print() is used to output a string.
Both echo() and print() are not actually a real function, it is a language construct.
So you are not required to use parentheses with its argument list.
echo() can take more than one parameter when used without parentheses.
print() only takes one parameter.
echo() is not a real function ,so it does not return any value. Though print() is also not a real function, but it will always returns 1.
echo() has a shortcut syntax, this short syntax only works if the short_open_tag configuration setting on php.ini is enabled.
Example of short_open_tag:

<?php

    $blog_address="http://shafiq2410.wordpress.com/";

    ?>

    <p>My Blog address is: <a href="<?=$blog_address?>" target="_blank"><?=$blog_address?></a></p>

How to Comment your code in PHP?

PHP supports 'C', 'C++' and Unix shell-style (Perl style) comments.
You may use any style based on your requirements.
Single-Line code comments use C++ Syntax
Multiple-Line code comments use C Syntax
Unix Shell Syntax (Perl Style) is also used for single line comments
Example: Single-Line C++ Syntax

 <?php

        // Title: My first PHP code

          echo "This is a PHP program.";

    ?>

Example: Unix Shell Syntax

 <?php

       # Title: My first PHP code

          echo "This is a PHP program.";

    ?>

Example: Multiple-Line C Syntax

<?php

    /*

    Title: Test Code

    Author: shafiq

    Author URL: http://shafiq2410.wordpress.com

    Email: shafiq2410@gmail.com

    */

    echo "This is a PHP program.";

    ?>

How does code is separated in PHP?

PHP requires instructions to be terminated with a semicolon at the end of each statement.
The closing tag (?>) of a block of PHP code automatically implies a semicolon(;)
(Ref-Example 2), so you do not need to have a semicolon terminating the last line of a PHP block.
Example 1:

<?php

        echo 'This is a test';

        echo 'This is another test';

    ?>

Example 2:

1	<?php echo 'This is a test' ?>

Example 3:

1	<?php echo 'We omitted the last closing tag';

Note: The closing tag of a PHP block at the end of a file is optional and in some cases omitting it is helpful when using include() or require(),
So unwanted white space will not occur at the end of files, and you will still be able to add headers to the response later.

Learning PHP, MySQL & JavaScript: With jQuery, CSS & HTML5 (Learning PHP, MYSQL, Javascript, CSS & HTML5)

What are the Syntax of PHP programming language

When PHP parses a file, it looks for opening PHP tag "<?php or <?" and ending php tag " ?>" which tell PHP to start and stop interpreting the code between them.
Everything outside of a pair of opening and closing tags is ignored by the PHP parser. Example:

 <p>This is going to be ignored by PHP Parser.</p>

        <?php echo 'While this is going to be parsed.'; ?>

    <p>This will also be ignored by PHP parser.</p>

PHP code must have a semicolon ";" at the end of each statement.
The closing PHP tag "?>" automatically insert a semicolon.
Example:

<?php
    echo 'PHP is Fun to learn !!';
?>
<br>
<?php  echo 'PHP automatically insert a semicolon at the last closing tag' ?>
<br>
<?php echo 'If a PHP file have only PHP code than the last closing tag can be omitted';

Example Advanced escaping

<?php

        if ($expression) {

        ?>

        <strong>This is true.</strong>

        <?php

        } else {

        ?>

        <strong>This is false.</strong>

        <?php

        }

        ?>

Before PHP version 7 There were four different pairs of opening and closing tags which could be used in PHP. Standard tag is always available Example: Script tag is also always available Example:

1
2
3

<script language="php">echo 'some editors (like FrontPage) don\'t like processing instructions';

            </script>

Short tags can be turned on and off from the php.ini configuration file. Example:

1	<?= expression ?>

This is a shortcut for

1	<? echo expression ?>

ASP style tags can be turned on and off from the php.ini configuration file Example:

1	<% echo 'You may optionally use ASP-style tags'; %><%= $variable; # This is a shortcut for "<% echo . . ." %>

Difference between the break and continue in programming language

Break

The break statement will terminate iteration of the loop and continue executing if there is any code that follows after the loop. Example of Break statement in JavaScript:

<script>

x=0;

for(x=0;x<10;x++)
{
if(x==3)
{
break;    
}
document.writeln("x=" + x + "<br />");

}


</script>

Output: x=0 x=1 x=2

Continue

The continue statement will terminate the current execution of loop and resume the loop with the next value if any. Example of Continue statement in JavaScript:

<script>

xx=0;

for(xx=0;xx<5;xx++)
{
if(xx==3) 
{
continue;
}
document.writeln("xx=" + xx + "<br />");
}

</script>

Output: xx=0 xx=1 xx=2 xx=4
