C++ can be pretty harsh on newbies and you need to be patient while learning it. 
There are programmers out there with more than 10 years of experience in it and still out there learning the intricacies of the language.     
With that said, please understand that the best way to learn a language is by making lots and lots of programs in C++.  
You can try your hand at competitive coding and start solving problems in C++.  This has many benefits :- 
1) You'll learn about the standard library provided by C++. 
2) You'll get good at debugging your code. 
3) You'll be able to code faster. 
4) Competitive coding is fun, so you won't be getting bored easily. 
Whatever way you take, you have to code a lot of programs in C++ to at least get a basic hold of the language.
