Introduction to modern C++

It is now often to see on the internet recently talks about modern c++. Many people wonder on what modern c++ is, is it a new language on it own? Is a new language created from c++ just like c was created from c. No my friend it is not a new language, think of it as an update to c++, so as to fit in with modern programming languages like JavaScript, Go, Rust, Dart, Java 8 etc.

Which c++ is old and which one is modern?
The old version of c++ are, c++98 and c++03
While the new ones are c++11, c++14,c++17 and the proposed c++2a (2020)
