PROGRAMMING
Today,s computer come in many different forms like that massive,multipurpose,mainframes and supercomputers to desktop-size personal computers. personal computers,on the other hand, are small and inexpensive.
computer only work in the basis of programming.
How To Develop A Program :
every program consists of manly three parts (1) input , (2) processing , (3) output.
so when we develop a program we must keep in mind these three things.
These three steps are called algorithm in programming language.
Types Of Programming Languages:
There are many different languages are used to program a computer. usually computer program written in some high level languages because these are easy to understand.
c , c++ , c# , java , dot net are some examples of high level languages.
high level languages offers three advantages over machine language such that simplicity, uniformity, and portability.
Difference in syntax between C and C++ :
c and c++ both are high level programming language and both are related to each other.
3G:
3G or 3rd generation mobile telecommunications is a generation of standards for mphones and mobile telecommunication services fulfilling the International Mobile telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union.[1] Application services include wide-area wireles voice telephone, mobile Internet access, video calls and mobile TV, all in a mobile environment. To meet the IMT-2000 standards, a system is required to provide peak data rates of at least 200 kbit/s.
Recent 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in
laptop computers.
3G in India
11 December 2008, India entered the 3G arena with the launch of 3G enabled Mobile and Data services by Government owned Mahanagar Telephone Nigam Ltd MTNL in Delhi and later inMumbai.MTNL becomes the first 3G Mobile service provider in India. After MTNL, another state operator Bharat Sanchar Nigam Ltd. (BSNL)launched 3G services on 22 Feb 2009 in Chennai and later launched 3G as Nationwide. The auction of 3G wireless spectrum was announced in April 2010 and 3G Spectrum allocated to all private operators on 1 September 2010.The first Private-sector service provider that launched 3G services is Tata DoCoMo, on November 5, 2010. And the second is by Reliance Communications, December 13, 2010. Vodafone Launched their 3G by mid of March,2011 . Then, Bharti Airtel launched their 3g services on 24 January 2011 in Bangalore and also launched in Delhi & Jaipur on March 4, 2011(not GSM but only USB estick). Aircel also launched 3G in Kolkata in the month of February.Idea also launched its 3G services in mid April. Other providers like Virgin are expected to launch 3G services by Q1 2011.
All the operators provide 3G services on the 2100 MHz band. As of now, the Government owned BSNL is the most successful company with the subscribers of 3G service. It has more than 3 million subscribers of its 3G service. It also has the widest coverage with around 826 cities across the country.
The private operators like IDEA and Reliance are increasing their 3G coverage as well as the number of subscribers.
The 3G service is used by the minority users in the country who own 3G handsets and the prices of the 3G services are currently out of reach of the pockets of most
Indians. This led to the slow adoption of 3G. but the scenario is changing quickly with the introduction of cheap 3G handsets.

Difference in syntax between C and C++ :
c and c++ both are high level programming language and both are related to each other.
- In c++ we used cout and cin as output and input functions instead of printf and scanf functions in c.
- In c++ we include <iostream.h> header file instead of <stdio.h> in c.
- C++ follows the concepts of oops(object oriented programming language) while c does not.
- In c++ we can create classes and its objects while in c we can't.
- enumaration declare in c language within a structure act as globally but declare in c++ within a class or structure , it is particularly of that class and structure only.
- C++ permits explicit type conversion of variables or expressions using the type cast operator.In c we use such that (type_name)experession and in C++ we use such that type_name(expression).
- IN c++ we can use overloading concept but in c we can not use.
