Career

Hello Akash,
It's good to know that you are looking forward to a career in software engineering. At the moment, you need to work really hard to secure a good percentage in your 10th and 12th board examinations. 75+ would be a decent percentage.
You need to understand the basics of physics, chemistry, mathematics and computers. This will help to increase your board examination percentage. Once you have entered the 11th standard, I would recommend you to join an engineering coaching institute. They will help you prepare yourself for engineering. They also conduct periodic tests which help you analyze your preparation level and you can study accordingly.
Once you've entered 11th standard, you should also solve various model test papers and competitive papers for AIEEE/IIT. Every time you complete a chapter of your 11th/12th syllabus, solve related IIT/AIEEE questions related to the chapter you completed. This will improve your knowledge on the chapter. Such competitive books are easily available in the market. This will also help you crack the various entrance examinations that you will appear for after passing 12th.
Ensure your percentage in class 12th is over 75 (at least 70). After you are done with your board examination, you should appear for the following entrance examination:
1. IIT JEE and IIT Advanced for admission into IITs.
2. AIEEE for admission into NITs and other government colleges.
3. Individual state examinations (OJEE for Odisha, COMEDK for Karnataka, EAMCET for Andhra Pradesh/Telangana etc.) for admission into private colleges in respective states.
The more the entrance examinations you appear for, the more options for colleges you will have for yourself.
Once you secure your position in a good college, ensure you maintain at least 70 percent throughout with no backlogs to be eligible for placement interviews in most companies.

Hello Ayush,
Facebook and WhatsApp aren't dependent on just one programming language, they involve many. A markup language for designing Front End user interface (probably XHTML/CSS), web programming to validate data (probably PHP), security validation for logins and privacy settings (probably JAVA servlets), a background database to store information (probably SQL/Oracle Database), a pipeline to connect the user interface to the database (probably JDBC/ODBC). Along with these, there could be many more programming languages being used as per the requirement.
Building such an application isn't the job of a single person. It involves a team in which there are members skilled in at least one of the languages being used in the application.
I hope I have been able to answer your queries to your satisfaction.
