Why Java is Platform Independent and C, C++ not !!

Posted by Tushar Bedekar
Most of the people have confusion regarding this Question. So I have decided to write something on this topic. Now we will go step by step whats this

What a Platform means to us

The operating system installed on the computer is known to be a platform. Each and every operating system have different structure and format. These operating systems (platforms) differs on the basis of the following factors

  • Like the way they execute the files. 
  • On the basis of system kernels
  • The way the optimize the system for best performance and make use of processor
  • On the basis of different file extensions, etc
For example, Windows operating systems executes .exe files. 
                       Linux here everything is a file. And also here there is no specific extension. Any file                            can be executable here
                       similarly, we have Unix and Mac Os  that have their own file extensions.

Platform Independent Vs Platform Dependent

Platform Independent means the program that we have developed can run / execute (show results) on any platform. That is on any operating system.

Platform Dependent means the program / software that we have developed can run /execute (show results) on a specific platform. That is on a specific operating system.

Why Java is Platform Independent and C, C++ not !!

The programming language like C and C++  do not generate any intermediate code like bytecode in java. The C and C++ generate directly Native Code which is specific to one platform or operating system. This Native code is known as object code (Machine Code ). 

As we also know that Object Code (Machine Code) generation requires some Operating system files to be included which makes it platform dependent.
Whereas in Java we have intermediate code by the name of Byte Code (not a machine code). This can is understandable by JVM (Java virtual Machine) which converts it to the object code (machine Code) . That  why in order to run Java code we need JVM installed on the device which makes java Platform independent.

HTML Basics

Posted by Tushar Bedekar
All the webpages in HTML are defined in terms of document object model (DOM). There are various different document of HTML known to be as a HTML tags < >. These are known to be as the elements of the HTML

  • root tag <html>    </html>
  • <head>    </head>
  • <title>    </title>
  • <body>      </body>
The <html>    </html>tag is known as root tag of a tree and rest tags are known as elements of the tree or can termed as branches of the tree. The tree here is nothing but the webpage.

Each and every page in html is defined by its Doctype deceleration. This deceleration may be optional in some HTML versions. The Doctype deceleration help the browser to display the contents of the webpage correctly in the way that is needed by the developer of the webpage.

<head>    </head>  the program or the code/ statement written inside the head tags is only for the browser, that is it is not displayed on the web browser. Here the developer can define the metaname  which is discussed later. meta content and favicon image and other links etc. CSS (cascade style sheets) is also being putted here.

<title>    </title>   it is used to declare the title of the webpage. for example for this webpage the title tag can be written as 
<title> Advance Computing And Programming </title>

<body>    </body> the content that is to be displayed on the webpage is being written here. various different types of tags are used in this section to display different element of the webpage. Advance collection is being discussed later.

Example:


<!DOCTYPE html>
<html>
<body>

<h1> FirstHeading </h1>
<p>My Name is Tushar Bedekar</p>

</body>
</html>

Key Note:-

  • The HTML files are stored with .html extension
  • The Homepage of any webpage is Index.html
  • This webpage HTML code can be viewed by pressing Ctrl + U

Guide to Finding the Best Spying Apps

Posted by Tushar Bedekar

When we live in a world where fraud and deceit dwell at every single corner, it is hard to find reliable spy software for phone or other similar device. Plus, with their demand on the rise, it is getting harder every day to discern the good applications from the bad ones when you have the safety of your loved ones at stake.
When you are looking for reliable spy software, you should be concerned about two things.
  1. You need to buy good and reliable software that is easy to use, untraceable and safe.
  2. You need to find a program that matches your requirements in terms of it monitoring methods as well as its compatibility with the target phone.
Unfortunately, buying good mobile monitoring software can be slightly tricky. Not because of its compatibility with the target phone and its accessibility from a remote server, but because of its reliability. You know quite well what mobile phones are being used for now a days. From picture messages to Facebook chats, unless you are using reliable spy software, you are at the risk of releasing your personal data to the entire world.

How to discern a Good Spy Application or a Bad one?

This, even though just might be one of the most sought out question of them all when it comes to spy applications, but it also is the one where you cannot find much information about. Therefore, we are here to help you out of this tight spot and help you recognize a good spy application.

·         Evaluating Software Companies

Now this is the tricky part, one that you cannot figure out without expert advice – evaluating a software company.  Here are a few tips about what to look for in spy software.
-        Whether the software has a bug-free, professional looking site?
-        Does the site provide you with the company’s contact information i.e. the phone number, address, email, etc?
-        Does it respond to a live chat quickly?
-        Do they reply to your email or a call with a personal response?
-        Do they have reliable looking Facebook and twitter pages that are regularly updated?
-        What information do they provide on the site?
-        Do they give detailed information about how to install and use the software?
-        Do you need to look for further information or their FAQ answers most of your queries?
If, based on the site and software in question, most of the fore-mentioned questions are answered in yes instead of no, then the software may just be reliable.

  • Look Them Up
One of the best, even though it may just be the most manipulated medium as well, to establish a product’s web presence is to Google it. If it is a reliable website, it will show up on the first page of search results, and if not, then you know they answer.
Plus, steer clear of the spy software about which you cannot find any sort of information. Also, do not believe anything that you read about software point blank, read everything about the product and then make up your own mind about it.

  • Online and User Generated Reviews
Reviews, by both the experts and the user of that particular software, is a good way to learn more about a product, since the review writers are not trying to sell the product, but merely share their own opinion about the product they have evaluated or used.
But, the thing is, most of these reviews are actually phony and a sham, written by people who have never used the product and are being paid to do so. Thus, use your own judgement here as well, when it comes to spy software like TheOneSpy, who reliability and quality we can swear on.
Still, we stand by what we said, user generated reviews are usually reliable when posted on sites like Amazon, since they wouldn’t someone leave a review who hasn’t actually bought the product in question.

  • Pricing and Term Contracts
Mostly, the best spy applications have similar pricing structures since they are in competition, therefore their rates do not vary much. But, if you find a deal that is too good to be true and offers things like;
-        Free
-        Cheap
-        Half Price if you order right now.
-        One-time payment
-        Free Lifetime upgrades
Then, shut the site immediately and swear to never open it again as long as you shall live.
  
This might sound extremely harsh in your opinion, but this is what spy software industry has come to. Even though you might feel at times that the person selling the said product is saying the truth, you can never be 100% sure of it. Most sites are here to make a quick buck by selling you faulty spy software and then earn a little more by leaking out your personal data. Thus, tread carefully. These are dangerous passages.

How We Can Have a Nested Return In a Function

Posted by Tushar Bedekar
Let us First Understand what is required and what the question is all about.Actually we are discussing about nested return in the function. that is return within the return  so follow is the programme which is conveying the same.Her we have taken the two function name "Factorial" and "Sum" which are calculating the factorial of a number and the result of the factorial  is returned to the function name sum which is calculating the sum of any number


#include <stdio.h>
#include <stdlib.h>

int factorial();
int sum();

int main(int a)
{
    int c;
    printf("\"enter the a number\"");
    scanf("%d",&a);

    c=sum(a);
    printf("The required result is %d \n",c);
    getchar();
    return 0;
}

int factorial(int y)
{
    int i,fact=1;
    for(i=1;i<=y;i++)
    fact=fact*i;
    printf("The factorial of a number is %d \n",fact);
    return fact;
}

int sum( int x)
{
    int result,k;
    printf("enter the number whose factorial is required \n");
    scanf("%d",&k);
    result=x+factorial(k);
    return result;
}

Difference Between Procedure Oriented Programming (POP) & Object Oriented Programming (OOP)

Posted by Tushar Bedekar

Procedure Oriented ProgrammingObject Oriented Programming
Divided IntoIn POP, program is divided into small parts called functions.In OOP, program is divided into parts called objects.
ImportanceIn POP,Importance is not given to data but to functions as well as sequence of actions to be done.In OOP, Importance is given to the data rather than procedures or functions because it works as a real world.
ApproachPOP follows Top Down approach.OOP follows Bottom Up approach.
Access SpecifiersPOP does not have any access specifier.OOP has access specifiers named Public, Private, Protected, etc.
Data MovingIn POP, Data can move freely from function to function in the system.In OOP, objects can move and communicate with each other through member functions.
ExpansionTo add new data and function in POP is not so easy.OOP provides an easy way to add new data and function.
Data AccessIn POP, Most function uses Global data for sharing that can be accessed freely from function to function in the system.In OOP, data can not move easily from function to function,it can be kept public or private so we can control the access of data.
Data HidingPOP does not have any proper way for hiding data so it is less secure.OOP provides Data Hiding so provides more security.
OverloadingIn POP, Overloading is not possible.In OOP, overloading is possible in the form of Function Overloading and Operator Overloading.
ExamplesExample of POP are : C, VB, FORTRAN, Pascal.Example of OOP are : C++, JAVA, VB.NET, C#.NET.

Class In Object oriented Programming languages

Posted by Tushar Bedekar
Basically, there  are various different definition of the classes in object-oriented programming language. Some basic definition are as follows:-


  • The class is said to be the collection of an object.
  • The class is said to be the collection of the data members and their member functions that are used to access and modify those data members.
  • The class is sometimes said to be the blueprint of an object.
     class Box
    {
       public:
       double length;   // Length of a box
       double breadth;  // Breadth of a box
       double height;   // Height of a box
     };
The C++ makes use of the keyword class followed by its identifier(Name of the class). Basically the class is said to be the collection of similar kind of an object.

The C++ classes have 3 different types of access specifier. They are as follows:
  • Public 
  • Private 
  • And protected. 

Keywords: private and public

Keyword private makes data and functions private and keyword public makes data and functions public. Private data and functions are accessible inside that class only whereas, public data and functions are accessible both inside and outside the class. This feature in OOP is known as data hiding. If programmer mistakenly tries to access private data outside the class, compiler shows an error which prevents the misuse of data. Generally, data are private and functions are public.

Keyword: Protected

But however the C++ makes use of another special kind of keyword (access specifier) Protected which is used to hide the data members and members function from being accessed from other class but allows the access from only the child class.

Data Members:

data member may be of any type, including classes already defined, pointers to objects of any type, or even references to objects of any type.Data members may be private or public, but are usually held private so that values may only be changed at the discretion of the class function members.

Member Function:

Member functions are operators and functions that are declared as members of a class. Member functions do not include operators and functions declared with the friend specifier. These are called friends of a class. You can declare a member function as static; this is called a static member function.


Further Topics will be covered in the next post.If you have any doubt regarding this section fell free to contact us     you can also join us at  Discussion Forum or E-mail us at
