I learnt turbo C++ in school, about 8 years ago and haven’t touched C++ ever since, which C++ should I learn? its getting difficult for me to follow the latest C++ versions since they have quite a bit of code idk about.

I tried learning some modern C++ codes but didn’t find good enough reasons to justify using them, like int main instead of void main or using std::namespace etc(not too sure if those were the names) etc
