Eligibility Of the Master of Computer Applications [M.C.A]
Graduation in any stream is the basic eligibility for MCA. The eligibility for qualifying marks in graduation differs from institute to institute. Most of the institutes require 45 to 50 % aggregate in qualifying exam for taking admission. Reserved categories get some relaxation in aggregate percentage.
Apart from this there is another prerequisite for taking admission in MCA degree; one must have studied Mathematics in 10+2 as a compulsory subject.
How to Get Admission in Master of Computer Applications [M.C.A]
Admission to MCA can be obtained either on the basis of entrance exams or directly on qualifying exam merit basis. Following are the general ways of admission in MCA program
Direct Admission- Direct admissions are done on the basis of merit in qualifying exam. Some institutes also provide admission on management quota, which is also way of direct admission. Management quota seats in every college are reserved. Fee is generally higher for these seats than general seats.
Entrance Test- After taking entrance test conducted by various universities, qualified students are called for counselling. Counselling is conducted for seat allotment in various colleges under that university. Admission is done after allotment of seat in counselling.
Entrance tests for MCA admissions
There are several state level/university level entrance tests for admissions.
IPUCET- Conducted by GGSIP University for admission to university and its affiliated colleges in Delhi.
TANCET- Conducted by Anna University for admission to university campus and other colleges in Tamil Nadu.
NIMCET- NIMCET is NIT MCA Common Entrance test, a National Level Test conducted by NITs for admission in to their MCA programs.
BIT MCA Entrance Test- Conducted by BIT Mesra for admissions to its MCA program.
WBJEE- Conducted by West Bengal Joint Entrance Exam Board for admission in all technical institutes of West Bengal
UPSEE- Conducted by Dr. APJ Abdul Kalam University (Formerly UPTU) for admissions to various colleges in Uttar Pradesh.

Hello,
In the IT world, there is an excessive demand of those programmers who are expert in the field of R programming. There is no specific eligibility criteria or any prerequisite to learn R programming at all. This is the easiest computer language. If you are smart enough, then you can even learn this language while just reading books and watching the tutorials on YouTube.
This programming is in demand, because R language can handle the enormous amount of business data. It is much possible that system may get out of order, because of storage incapacity. R programming can easily solve this problem, because this language can handle the petabytes of business data. Another big feature or advantage of learning this is that it is stastical application more than just a language. Hence, it supports embedding compiled code in other language like FORTRAN or C.
So, this makes the R Programming an essential elements for all the programmers to learn.

Firstly, I'd be cautious to make a claim that C++ is better than Java. There are pros and cons to both sides.
C++ is basically more power to the programmer (since one can break past all sorts of abstractions), and runs natively instead of on a virtual environment (and hence is also platform dependent). A C++ application can manage its own memory in more finer ways than a Java app can. In C++, one can overload operators, access physical addresses and override values there. One can throw and catch any type (.) and do some nasty stuff around all that. On the other hand, in Java, one can sit back and basically just deal with OO abstractions and code them up in one-way, regardless of the underlying platform. Fine-grained memory management is harder. One can play around with GC params for optimizations and get really far this way, but anything more is not really achievable. In C++, you can easily get as deep as you want to.
But, also remember, with great power comes great responsibility. An irresponsible Java developer would be less harmful to your software, than an irresponsible C++ developer would be. In that sense, Java is a relatively easier and simpler language to work with, than C++ is. With C++, a lot of responsibility and burden is on the shoulders of the programmer and with Java, a lot of this, is taken care of, by the system.
There is also a popular performance myth with C++ and Java. Since C++ runs natively, it used to run faster in most platforms than Java does, given the VM is basically emulated. However, this is increasingly being rendered moot, as JVMs end up being very powerful, and processor speeds and architectures have evolved a lot over time.

Hi,
These are some of your options today as a JavaScript developer.
HTML, CSS, and JavaScript/JQuery: You can make stand alone websites or websites that connect to a back-end, which will be handled by a separate team. You might have to work on frameworks such as Bootstrap and Semantic UI (which make your job a lot easier once mastered).
Angular/ Backbone/ React/ Vue/ Ember: All of these are JavaScript frameworks/libraries for building single page, highly interactive websites. Consider these as an icing on top of everything mentioned in the previous point. All of these solve the same problem differently, and you will have to work with whatever suits your or your employers needs.
Node JS: Thanks to Node, you can also dive into the back end/server side programming without having programmed in any other language except JavaScript.
The MEAN/MERN stack: Pick an MV* framework from point 2, add Node from point 3, and throw in a database (Mongo DB in this case). There, you are now a full stack JavaScript developer. Okay, you are not, but you just added a lot of value to yourself.
Mobile/cross platform app development with Ionic/PhoneGap/React Native: All of these use JavaScript and other supporting technologies. Not many people take them seriously though.
There are also complete solutions like Meteor, which pretty much handle the back end for you, and let you focus on the UI. You can choose from Angular, Blaze, and React for the UI.
To sum it up, there are ton of opportunities right now, but that doesnt mean its going to be like this forever. If we were talking about something rock solid, like Java, I could rest easy knowing my job is secure, at least for a while. With the web, its a new, shiny thing everyday. We love jumping wagons.
All the best.

.NET is an Object Oriented Programming language which can be used for building and running of software applications for Windows, Windows Server, Windows Phone, Microsoft Azure, and XML Web services. It is included as a part of the curriculum for various degree courses in computer science and computer applications in many Indian universities. However, this course can be pursued separately as a certification program in any computer training institute. In the latter case, the time duration, fees and eligibility criteria vary from one institute to another.
On a personal node, I would suggest NIIT, GNIIT and Appin Technology Lab for enrolling into a certification course in .NET. These choices have been made considering the widespread reachability, affordable fees and placement opportunities provided on completion of the course. However, other institutes can also be a good alternative, provided they have good faculties. The key concept is to have a clear idea about the programming concepts, paradigm and ability to find a solution to any problem.

Since you aren't a complete novice, I think you're ready for C++, for the following reasons:
It's dangerous. Some may think this is a reason to avoid it, but these are things you are going to have to learn.
It's close to the hardware. This makes it fast and optimization and also suitable for tiny little boxes.
It has a good preprocessor. It's as dangerous as juggling chainsaws, but when you start developing a code base that has to compile on multiple systems, you'll really appreciate it.
It has objects without pointers. Traditional objects always have pointers. C++ lets you have objects that are not allocated and not accessed by pointers. Instead, they look like any other data type. This allows some choices that you might not ordinarily make when thinking in terms of objects, which, because of 2, you can optimize to zero cost for production. My favorite example is units. We lost a $328 million Mars orbiter because of different units of measurement (see MARS CLIMATE ORBITER TEAM FINDS LIKELY CAUSE OF LOSS). It's easy to make a units system in C++ and tweak it for hacking, debugging, and running. Also think currencies.
It has a template system. I think this is the most amazing thing about C++ per se. It has been reported that the system is so powerful because of an early implementation made it more powerful than specified. Good. When you can use templates effectively in C++, you're an expert in C++.

Hello,
Job opportunities in government sector:
These days government at all levels are trying to reduce manpower. This is because, the expenses on salary are nearing 50%. Whereas, as per norms, it should not go beyond 35%. So, how does government function, it is functioning nowadays, by simply outsourcing many activities that it did earlier. This avoid expenses on permanent staff of the government. In addition, people are happy as they are getting the services efficiently.
In such scenario, it is useless to wait for government job. However, some recruitment will definitely occur. But, it is going to be on a lesser scale than in earlier years.
This does not mean that jobs have shrunk. There have just shifted from government domain to private domain. Of course, being in private domain means the candidates need to be on their toes always.
