What Is Media Query In Using CSS BootStrap.....

                             What Is Media Query?

One of the most important features of style sheets is that they specify how a document is to be presented on different media: on the screen, on paper, with a speech synthesizer, with a braille device, etc.

1. here are currently two ways to specify media dependencies for style sheets:

• Specify the target medium from a style sheet with the @media or @import at-rules.
• Specify the target medium within the document language.

For e.g:-

<style tyle="text/css">

<!--

@media print {

    body { font-size: 10pt }

  }

  @media screen {

    body { font-size: 12pt }

  }

  @media screen, print {

    body { line-height: 1.2 }

  }

-->

</style>

What are Difference between (= =) and (= = =) this Two Relational Operators ?

            What are Difference between (= =) and (= = =) this Two                              Relational Operators ?

Ans:-   The  Relational Operator (a = = = b)
                  a = = = b                    a = = b when a and b are two string objects that contain equivalent characters, the = = = operator will still return true.

For e.g :-

The languages JavaScript and PHP extend this syntax, with the "= =" operator able to return true if two values are equal, even if they have different types.

(for example: "4 = = "4"" is true) and the "= = =" operator returning true only if two values are equal and have equivalent types as well (such that "4 = = = "4"" is 

false but "4 = = = 4" is true). This comes in handy when checking if a value is assigned the value of 0, since "x = = 0" is true for x being 0, but also for x being "0" 

(i.e. a string containing the character 0) and false (as PHP, like other languages, equates 0 to false), and that is not always what one wants, but "x = = = 0" is only 

true when x is 0. When comparing objects in PHP 5, the "= =" operator tests for structural equality, while the "= = =" operator tests for physical equality.

Types Of Operator......

                 Types Of Operator......

1) Unary Operator:-

The following operators are unary:

• Increment: ++
• Decrement: − −
• Address: &
• Indirection: *
• Positive: +
• Negative: −
• One's complement: ~x
• Logical negation: !x
• Sizeof: sizeof x, sizeof(type-name)
• Cast: (type-name) cast-expression

2)Binary Operator:-

A binary operator is an operator that operates on two operands and manipulates them to return a result.

Some common binary operators in computing include:

• Equal (= =)
• Not equal (! =)
• Less than (<)
• Greater than (>)
• Greater than or equal to (> =)
• Less than or equal to (< =)
• Logical AND (&&)
• Logical OR (||)
• Plus (+)
• Minus (-)
• Multiplication (*)
• Divide ( / )

3)Ternary Operator :-

                                          

syntax :- test ? expression 1 : expression 2

Parameter :-

testAny Boolean expression.
expression 1An expression returned if test is true. May be a comma expression.
expression 2An expression returned if test is false. More than one expression may be a linked by a comma expression.

For e.g :- 

JavaScript

var now = new Date();
var greeting = "Good" + ((now.getHours() > 17) ? " evening." : " day.");

Introduction Of HTML 5

                       Introduction Of HTML 5

HTML 5 is a co operation between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG).

WHATWG was working with web forms and applications, and W3C was working with XHTML 2.0. In 2006, they decided to cooperate and create a new version of HTML.

* Some rules for HTML 5 were established:
•New features should be based on HTML, CSS, DOM, and JavaScript
•Reduce the need for external plugins (like Flash)
•Better error handling
•More markup to replace scripting
•HTML5 should be device independent
•The development process should be visible to the public

                     strike out tags

Strike out tags:-

strike out tags used for the display the content ,

like wise login is not succuss success 

tags:-  <p>login is<strike>not succuss</strike>success</p> .

                  Audio hide and videos tags

                                         Audio hide

using  style="visibility:hidden" these properties audio are hide .

<audio controls=""  style="visibility:hidden">

14.Explain Serialization and Deserialization in C#? 
Ans:-

• Serialization:-It is the process of converting an object into stream of bytes.
• Deserialization:-Deserialization is the process of converting stream of bytes into object.
• There are 2 types of serialization.

           1. Binary Serialization.
           2. XML Serialization.

• We need to use namespace:

             1. System.Runtime.Serialization
             2.System.Runtime.Serialization.

• If we have to use string data, then there is no need  of serializable.
• It is used in case of complex data.

Program :- To store object in file and

read it using serialization.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

namespace Serialization_eg

{

class Program

{

static void Main(string[] args)

{

//Serialization

FileStream fs = new

FileStream("C:\\SDemo.txt",

FileMode.Create);

BinaryFormatter obj = new

BinaryFormatter();

obj.Serialize(fs, DateTime.Now);

fs.Close();

//DeSerialization

FileStream fs = new

FileStream("C:\\SDemo.txt",

FileMode.Open);

BinaryFormatter obj = new

BinaryFormatter();

DateTime dt =

(DateTime)(obj.Deserialize(fs));

Console.WriteLine(dt.Date);

}

}

}

Program :- To Serialize Our Own Class.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
namespace Serialize_own_class

[Serializable]

class Product
{

public string Name;
public double Price;
public int Quantity;
public double Total;
public Product(string n, double p, int q)
{

Name = n;
Price = p;
Quantity = q;
Total = Price + Quantity;
}

}

class Program
{
static void Main(string[] args)
{

// Serialization\\\\\\\\\

Product p = new Product("Comp", 1000, 5);

FileStream fs = new FileStream("C:\\SerDemo.txt",
FileMode.Create);

BinaryFormatter obj = new BinaryFormatter();

obj.Serialize(fs, p);
fs.Close();

//Deserialization\\\\\\

FileStream fs = new
FileStream("C:\\SerDemo.txt", FileMode.Open);

BinaryFormatter obj = new
BinaryFormatter();

Product p = (Product)
obj.Deserialize(fs);

Console.WriteLine(p.Name);
Console.WriteLine(p.Quantity);
Console.WriteLine(p.Total);
fs.Close();

  }

}

• If we don’t want particular variable to be serialized then use [NonSerialized] .
• IDeserialization CallBack is a method. It should be written in front of class name.
• If we want to implement it, then  

\\\\\\\\\\\\\\\\\\\\\\useOnDeserialization\\\\\\\\\\\\

Program :- To make use of NonSerialize.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

[Serializable]

class Product : IDeserializationCallback
//class Product

public Product(string n, double p, int q)
{
Price = p;
Quantity = q;
}
public void OnDeserialization(object sender)
{
Total = Price * Quantity;
}
}

class Program
{
static void Main(string[] args)
{

\\\\\\\\\\\// Serialization\\\\\\\\\\\

Product p = new Product("Comp", 1000, 5);
FileStream fs = new
BinaryFormatter obj = new BinaryFormatter();
obj.Serialize(fs, p);
fs.Close();

\\\\\\\\\\\\\//Deserialization\\\\\\\\\\\\\\

FileStream fs = new
BinaryFormatter obj = new BinaryFormatter();
Product p = (Product)obj.Deserialize(fs);
Console.WriteLine(p.Name);
Console.WriteLine(p.Quantity);
Console.WriteLine(p.Total);
fs.Close();
        }
     }
}

                foreach (object Name in objs)

                {

                    Console.WriteLine(Name);

                }

            }

            catch (ArrayTypeMismatchException e1)

            {

                // Not reached; "Academy" is of the correct type.

                System.Console.WriteLine("Exception Thrown.");

            }

            try

            {

                Console.WriteLine(e2.Message);

                // Always reached, 13 is not a string.

                Console.WriteLine("New element is not of the correct type.");

            }

            // Set objs to an array of objects instead of

            // an array of strings.
