I just learned C and I have created some projects like Parking System and Library Management System. My problem is I don't know mathematics and I want to learn DataStructures & Algorithms and become pro in it. In the whole September I will still be focusing on C and create more projects. I have started learning Mathematics today from High School level to College level. I thik maths will take 1 year to complete. After September in the October I want to start learning C++ and finish C++ till the end of Dec 2019. I want to know that do I have to first finish my maths learning which will take 1 year then I should start learning Data Structures and Algorithms? As I said I want to become a professional in Algorithms. I think its not possible to learn DS&A yet I have to wait 1 year till I finish learning my Maths. I can't do more with C & C++ without knwoing DS&A? If I started learning DS&A with C++ in the future then I can't become good at algorithms? I want to do competitive programming and be at Top 1 of Hacker Rank and other sites like this.

I am learning C++ and I want to develop my own custom ROM for android from AOSP which is Android Open Source Project. I don't know anything about how to do it help on internet is not clear and on the Android official website there is no section for documentation and people on other sites say read documentation.

(heading)How a programming language is created? Because I want to make my own.(heading)

I am learning C and next I will learn C++, SQL,DS&A, Assembley, Lex&Yacc,Operating Systems, Computer Arcticture, Computer Networks because I think it's enough for my goal. The only reason I am learning this, to make my own C++ clone with my own knowledge. But I really don't know how can I create my own programming language like C++ from scratch. Like what are the first steps to began with. As I know that C, first step is Preprocessor then Compiler then Assembler then (Loader/Linker).

Anyone please give me a step by step guide like learn this language first then this then this. So I can finally reach that amount of knowledge which I can implement to create my own programming language like C++.
