Dear Aspirant

I hope you are doing good.

Firslty you need to follow roadmap of complete journey and take basic baby steps and dont rush into high level topics to not get demotivated

If you learn how to code in language ,then it will be very easy for you to change your language

You can follow abdul barry c++ basic to advanced course which is on udemy then start practising questions on gfg topic by topic . Try to built strong concept of OOPS and then start learning all the concept of data structures . In 6 months i can assure you will have very high command in coding

Hope you found this answer helpful. Good luck for your future
