C++ grows very fast! For example, the number of pages of the C++ standard went from 879 pages for C++98/03 to 1834 for C++20! Nearly 1000 pages! What’s more, with each revision of C++, we get several dozens of new features. Have a look at my blog post with all C++17 features, it shows 48 items, and my C++20 reference card lists 47 elements!
c++ 98/03 is just fine. C++ features should be used sparingly. you can write most of the code in "C" , STL and vary rarely define classes if absolutely necessary.
