Lets Start with c++...

Lets Start with c++...

C++ coding is done on IDE- Integrated Development Environment. It is a software application that provides a platform to run ,compile and execute High Level Programming language.

For C++ the IDEs are Dev C++ (recommended), Turbo C++, Borland C++ etc.
Every IDE has compilers which compile the written codes and check the errors and verifies whether the codes are following the correct logic, syntax etc which are required to run and execute the program successfully.

Below are the following formats that are required to follow to make the programs(coding) syntaxtically.

1. Header file declaration

Header files are the pre-compiled or pre-coded files with correct logic and syntax that includes in-built functions, class, structure etc. , which may directly or indirectly can be used in the program to avoid the program coding from being lengthy and hence make the execution time fast.
These files are stored in lib folder (library folder) of your respective IDE.

Header files comes with the extension ".h"(dot H).

For eg;
 if XYZ is a header file then it comes with "XYZ.h".

Syntax to be used in program to use header file:

#include<XYZ.h>

#include-(hash include) This is called pre-processor directives which means that these are the codings which are already been compiled and processed by the IDE compiler.

#- It is used as linking and loading the header files i.e, it act as a interface between the library file and programming.

include- This includes all the in-built functions, class and structures which are packed in the header file closed in < ......>.

Mostly used header files in C++:

#include<iostream.h>
#include<conio.h>
#include<string.h>
#include<math.h>
#include<stdlib.h>
#include<stdio.h>

Next Blog in-built functions and uses of the above header files.

Concepts Of C++ ...

Later, we discussed about the features of Object Oriented Programming (OOP). In this chapter, we are going to learn about the concepts that can be implemented by this paradigm, not in detail but a mild touch. We will be doing this in detail in the upcoming blog.

CONCEPTS:-

1. Class and objects
2. Data Abstraction
3. Encapsulation and Data binding
4. Data Hiding
5. Polymorphism and overloading
6. Inheritance and reuse-ability
7. Dynamic binding
8. Message passing

These concepts of OOP enable us to modify, give security and new mode of programming to our program.

These concepts we are going to deal, when we will be handling with "class".

Till then do remember these features and concepts.

Web Sites and Web Server in Asp.Net ...

WEB SITES :- Web Sites are nothing but a collection of the Web Pages that are hosted on web Server. They are normally preceded by HTTP://WWW.

WEB SERVER :- Web Server is a software that is used to host the Web Sites and Provide the basic infrastructure to host and run Web Sites. It can host one or more Web Sites.

example :-

IIS(Internet Information Services) from Microsoft works only on Windows.

APACHE Web Server

Glass Fish

Oracle Application Server

Tomcat Server

By default Windows include IIS in Client Operating System XP, WINDOWS 7, WINDOWS 8.

We can host only one website, but on Windows Server you can host n number of websites.

The Websites are primarily divided into two categories
1. Static
2. Dynamic

Static :- Static are those in which the content remain fixed and does not change as per the user requirement.
for example:-website of Schools cab be a Static Websites.
technology used is HTML, JAVA SCRIPT, CSS, etc.

Dynamic :- different from Static Websites when Websites interacts with the database and certainly form  web services(going to study after next few post) at the back end.
for example :-
just consider if gmail is a static website then
one user have 6 to 7 pages or some more like compose,inbox,draft,sent mail,promotion,home.
one user have approximately take min 100 messages then total number of pages=100*7.
Google have billion of user now how many static pages they are going to make. It can be go up to trillion of pages so it can not be done through static website so it can done by dynamic website.

technology used is ASP.NET,PYTHON,ASP,PHP,etc

NOTE :- A Browser only understand HTML, JAVA SCRIPT, CSS.
               then how browser understand that different kind of technology which we used for dynamic                  websites. for that we introduce scripting language.

There are two kind of scripting language-
1. Server-Site Scripting language.
2. Client-Side Scripting language.

Server-Site Scripting Language :- which runs on web server then output is generated in HTML and finally sent to the browser.
for example:-

ASP.NET - Active Server Pages(C#,VB.NET,)(.aspx)
ASP.NET MVC - Model View Controller(no extension)
PHP - Hypertext Preprocessor (.php)
Java Server Pages - (.jsp)
Ruby on rails
python
Java Servlets
Cold Fusion Markup - (.cfm)

Client Side Scripting Languages :-

Java Script - developed by NETSCAPE the member of the NETSCAPE have also develop Firefox.

VB SCRIPT - MICROSOFT - internet explorer

JQUERY accepted by all major companies so it becomes so successful. It purely works on the browser.

In the upcoming posts you can study more deep about ASP.Net and HTML.

Android Studio . How it works?

Android Studio


Android Studio is the integral development environment used for development of Android Apps.
It is based upon the IntelliJ Idea development environment and it is the Official development tool for Android Application development for Google play.

Android studio is based upon the concept of gradle.



So what is gradle in Android Studio ?
Gradle is nothing but a system that helps in the management of the following-

i.repository management.
ii.Build Management
iii.Version Management.
iv. Application Signing of App.


Thus the gradle helps in each and every task for our projects which we build using Android Studio. It is also called as the Control version System (CVS) for android.

Through the help of Android Studio we are able to visually create our application that includes layouts like Buttons, Radio Buttons, Check Boxes, Spinners etc.

When we use Android studio we are going to use JRE or JAVA as one component and android Architecture as Another Component.

We can use collections, Utility Classes from java and we can also use Android specific classes within Android Studio.

In the next post the installation of the IDE is demonstrated click here to download and install Android Studio.

Why C++ Programming ?

As the word defines itself "C + +" ,i.e "C Plus Plus" , quite similar like increment operator(++) in C, which means a step ahead of C language. This gives a whole picture that C++ includes all the features of C but along with it, it is a step ahead with new features.

As a whole we can say, C is the Subset of C++ ; where as C++ is the superset;

The main feature of C++ that makes it differ from C is that it comes with Object Oriented  Programming (OOP) paradigm where as C is a POP (Procedural Oriented Programming) or FOP (Function Oriented Programming).

OOP is a programming paradigm that enables to modularize the program by creating the memories for both data and functions that can be bind into one single unit and can used as templates and enables us to create such copies on demand.

OOP features;-

1.Follows bottom up approach.

2.More priority to data rather than procedure or algorithms.

3.Hide and give security to data from external user.

4.Data can only be fetched or access by what is known as methods or functions.

5.Program is divided into what is known as objects. 

6.Functions may communicate with each other through objects.

POP is a programming paradigm that gives more priority to procedure or algorithms.

POP features:-

1.Follows top-down approach.

2.More priority to procedures and algorithms.

3.No security and data can be accessed by outside programmer.

4.Program is divided into functions.

5.Functions may communicate through functions.

So, from the above  knowledge, we can conclude that C++ gives the flexibility to the users to use the language either POP or OOP .

Health tip of the day ... Tips for how to brush our teeth ?

Brushing - It’s best to use a medium soft brush and paste. Be sure to brush your teeth, tongue and gums thoroughly two times a day. Once in the morning and second time in the night after 40 minutes of taking dinner. Rinse – with aging as the flow of saliva is reduced in our mouth, it’s more likely that food particles will damage your teeth and gums more. Rinsing gets rid of the particles. Since some mouth washes are irritating to the gums, dilute it if necessary.

Android Architecture in details ...

Linux Kernel-

In the linux kernel  we have libraries and android runtime that helps to work with different concepts.
For example SqlLite is a library to store data within the App. We can have media libraries to interact with Videos, Audios and Pictures etc. We also have a very important library called as WEBKIT.

What is WEBKIT in Android?

Webkit is an browser engine powering safari, Google Chrome and Android Internet browser.

Android Runtime-

Android Runtime is a component which takes care of the core services like Google MAP, Location Service and also provides a runtime for running our apps on Google's  Android Operating System.

Android gives every required functions to a App like Memory Management, Device Mangment and other jobs which are the application requisition. Its the runtime's responsibility to interact with whom the App requiring.

The runtime environment actually targets different architectures which exist on different phones. The runtime is able to understand and push the native code according to Architecture of  the phone.

Application framework-

Application framework is a layer through which different applications can interact from various activities with the phone. Every application can interact with defferent kinds of frameworks like notification framework, View framework and telephonic fraework and others.

These frameworks are the basic building blocks for android architecture. These frameworks contains reusable codes, libraries, controls that any application can use for interaction.

Application-

Application layer is the top layer within android architecture.this layer contains two types of application.
1. Inbuilt application
2.User defined Application

1.Inbuilt applications-
Inbuilt apps like Telephony, SMS and browser etc.
They interact with the application framework but they are the integral part of the android system.

2.User Defined Applications- 

 These are the apps which are developed by the end user or the third party developer like Facebook Whatsapp or Twitter etc. They also interact with the application framework and work on the same manner as Inbuilt Applications

                                             The Architecture of  .NET framework 4.5 -

     

CLR (Common Language Runtime) -

                                                                   It is use for the execution of the .NET code within .NET FRAMEWORK. It is responsible for memory allocation, memory thread for hardware resources. It performs each and every function which are application in demand.

CTS (Common Type System) -

                                                                   This is an entity in .NET Framework meeting type compatibility in .NET Language. For example a Boolean data type in VB.NET and datatype in C# is determined by CTS.

CLS (Common Language Specification) -

                                                                     CLS is a subset of CTS and it contains minimum specification which every language has to satisfy.              For example: Python is one language that is .NET complied language. That means it can work with .NET.

ASP.NET Evolution in the Market ...

Till 2001 Microsoft is the king of the  software industry and most of the software’s are platform dependent only for its own operating system Microsoft Windows. But in the later years companies like Google, Ge-force, Apple and Amazon etc. give Microsoft a huge competition in acquiring the market position which force the Microsoft to change their Philosophy regarding their products and they do so for their survival.

.NET framework is completely a platform independent kind of web technology.

Before .NET

     VB        ---------------- >COMPILE ---------->creates .exe file which was

                                                                                      platform dependent.

 

AFTER .NET 

                    

                                                             

     VS                                      IL/MSIL                                next version of

C# .NET  ----->COMPILE------->.exe file  ------->INTERPRET      ARM, LINUX,
                                                                                               ANDROID

It performs on your code and change according to your platform                      

.NET FRAMEWORK

IL/MSIL:

Intermediate Language:

it is a set of instances that can run by a specific interpretation on a specific platform. It is primarily included to make the platform independent for certain languages to work.

It is very similar with Java and works as follows ;

Java---> Java code-->.class (Byte Code) ---> Interpret---> JRE, JVM (Plat. Inde)

VB.NET, C#---> .exe (Binary code) ---> Interpret--->.NET Framework

.Net framework 3.5 (2008)  and .NET framework 3.0

3.5 And 3.0 Framework was introduce when Windows VISTA was launched. Technology like LINQ, WINDOWS Communication Foundation, and Windows Workflow Foundation were introduce with windows VISTA.

In the upcoming posts you would come to know about .NET Framework 4.0 and 4.5 and I will also explain some of the common term like CLR, CLS, and CTS...

Introduction To JAVA

                 
 In this tutorial I will give you a brief introduction on Java. 

 Java is a computer language developed by SUN MICROSYSTEMS in early 90's and named as 'OAK' . It is a purely Object Oriented Programming language developed by James Gausling and Patrik. 

Major features of Java are -

 * Platform Independency

* robustness

* Distributed

* Secure

* Multi-threded

 * Portable and

 * Dynamic etc.

Java works on the paradigm "write once run anywhere" . It works on a framework called as JAVA RUNTIME ENVIRONMENT (JRE), it comes in different edition-

 

1) JAVA STANDARD EDITION(SE)

2)JAVA ENTERPRISE EDITION(EE)

3)JAVA MOBILE EDITION(ME)

                    JAVA STANDARD EDITION(SE) is used to develop client side applications,standard programs and applets which are not used by an enterprise.

                    JAVA ENTERPRISE EDITION(EE)  is used to develop server side applications and to handle projects related to enterprise and include frameworks like STRUTS,BEANS and others.

                    JAVA MICRO EDITION(ME) is used to develop applications for mobile devices such as cell phones,set up boxes and microwave etc.

Java is a free of cost distributed language which can be downloaded from oracle's website. Java works with the help of following methodology-

   JAVA PROGRAM---------->>>>Compile---------->>Class (Byte code)

           

                            (can be used in any environment).

Later on we will be using JDK for developing and compiling Java Programs.

Java Card: 

 A technology that allows small Java-based applications to be run securely on smart cards and similar small-memory devices.

JDK 

 

 JDK consists of a set of separate programs, each invoked from a command line, for developing and testing Java programs. It includes the JRE plus command-line development tools such as compilers and debuggers that are necessary or useful for developing applets and applications.
 

JRE

The JRE provides the libraries, Java virtual machine, and other components necessary for you to run applets and applications written in the Java programming language.

JVM

 The Java virtual machine (JVM) is an abstract computing machine that has an instruction set and manipulates memory at run time. The Java  virtual machine is ported to different platforms to provide hardware- and operating system-independence.

Here is a sample program-

For the compilation of this program , Firstly write this code on notepad then open command prompt 

and then write...

import java.lang.*;

class HelloWorld 

{

public static void main(String[] args)

{

System.out.println("Hello World");

}

}

Architecture of Android

Androids Architecture is a layered mechanism by which individual components can run and perform actions based upon the users. The lowest layer is of the LINUX kernel which primarily interacts with hardware and the device drivers.
In the Linux Kernel we have libraries and android run-time that helps to work with different aspects.
for example, SQLite is a library to store data within the App we can have media library to interact with videos and picture.

The passing of data from one app to another is done through a concept called as Inter-process Communication (IPC).
