I am in the 11th class and I want to become an android and IOS developer ......so I want to ask where to start for beginning what I should learn first. Pls guide me

Sharon Rose 26 August 2022

Hello sahil,

As of now as you are in class 11th so I would recommend that your major focus should be in your academics and you can do the research on this as a part time on weekends. 11th standard forms the crux of your future atleast till entrance examinations.

So, if you have taken computer science in your 11th std. then kindly focus on programming language which is been taught in school. Then you can start learning python then practice programming in platforms like hackerearth, code chef and a few more. You can practice from any one.

You can also study courses on app development from Coursera an udemy.

software engineer/developer can create advance app in any platform (Android,IOS, Windows)?

ayanmukherjee045 14 February 2022

Hi Karthik!

Yes, no doubt you can create your own app/advance app in any operating system such as Linux (Ubuntu or any other), Windows, IOS, Android etc. However, you will need emulator, studio or other basic frameworks to create an app which you can install/download easliy on any operating system.

Thankyou!
