(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++.
