This is the repository containing self-study notes for modern C++ to better prepare myself for workplace once graduate.

Teach-Myself-CPP

Hey! Welcome to this repository. This is the notes-keeping place for teaching myself C++, modern C++ in specific. It might also include some auxiliary topics about useful tools.

I learned traditional C++98 a few years ago and didn't quite work on this programming language recently. In order to better prepare myself for workplace once I graduate from school, I will teach myself modern C++ in leisure time and update notes here. Hopefully, this notes could also help other people wishing to get onboard with modern C++.

Aside from book reading notes, mostly I will be borrowing good resources from all over the repos on github, and re-implement them for deepening understanding. Sources are pointed out in each one.

I finished reading on

• <Effective C++>

• <More Effective C++>

• <Effetive STL>

• <Effective Modern C++>

• <C++ Concurrency in Action>

• <Design Data-Intensive Application>

Currently I am reading the comprehensive book <C++ Software Design: Design Principles and Patterns for High-Quality Software> to learn some design principles and best practices.
