I hope to start learning C++ sometime next year. Should I proritise studying C++11/14/17 to acquaint myself with modern practices, or C++98/03 so I can be better equipped to deal with legacy code?

Just learn C++. Start modern and you can learn older stuff later if you need to. It's really fucking simple.

I've looked at C, but I've been told that learning C before C++ increases the likelihood of essentially typing C code with classes instead of actual C++ code

You mean JavaScript.

OP, I suggest you drop all those low level languages that aren't suitable for coding anything in 2020 and look at things that are actually usable. If you want to do data/science go for Python. If you'll be working on apps or something look at Go or something else that's reasonably popular and doesn't carry historical baggage from the 70's.

Seriously? Swift for iOS or Java/Kotlin for Android, or even Dart for Flutter. Go isn't used extencively for apps, though it's quite based for server side micro services and similar.

Modern C++ is extremely fun. It ranks highest on my scale of "fun programming."
Then again, I think Javascript is fun too, so my opinions might just be retarded.

This is the method I took to learn C++. Best thing to do is pick up a book on whatever standard you like, start working through it and then start doing projects using that standard.
If you found that you need to work with legacy code it really shouldn't be hard to understand them.

I have no idea what you're on about. From research papers I've seen they use python solely for prototyping. Nobody right in the head would sacrifice computational speed for ease of implementations when your working with tons of data.

Literally look at github for the popular Ai/Machine learning libraries and you'll see tons of c++ code written for them.
>Tensorflow
A big proportion of the code is written in C++ and CUDA
>Microsoft CNTK
All written in C++
>Caffe
Written entirely in C++
>Torch
C

And so on.
>90% of all data science/Ai is written in Pythong
I really suggest you to look at the source code before typing something as ignorant as that.

Yeah, Python is mostly for prototyping and testing out some ideas to apply on a faster language. Glad to see that people still think like that. I hate when idiots say A is better than B without context.

90%+ of coding in IT is for legacy systems.

As soon as you've shown you can write new code to get out of a wet paper bag, you get reassigned to Legacy. Remember to ask for a rise because fixing old SW without breaking it is harder than writing new code. Try to find out the company's ratio of work on old and new code in the job interview. Yes, new code is more fun, but it involves design and architecture which go way beyond knowing a programming language.

You need to be able to read the old stuff, so go with C++14 or 17. Newer features are mostly available in the current compilers but that doesn't mean that you have to use them, or that companies already do. On top there may be grognards that stick to What Works, and knowing What Works is positive work experience.

You are retarded. While the libraries are in fact written in C++ or the likes, Python and other saner languages serve as the front-end, the access point. It gives you both the benefits of speed and the ease of use. While technically C++ is doing the work, you are nevertheless writing in Python. I suggest you stop being an elitist Cnile and start thinking rationally.

Yes, as a matter of fact if your C++ code doesn’t look like C with classes and templates you are doing something wrong. A newbie programmer will get burned learning c++ first. The fact that templates are consideres an advanced interview question in this era shows you the sad state of c++ programming in general.

I moved from pure to applied math PhD and they accepted the transfer without any cs prerequisites. Have been learning C++ to a graduate level since September and it’s a brainlet filter. Code does exactly what you tell it to do.

Because that’s what the language was designed for by Bjarne originally. Over time he unfortunately changed his philosophy to make C++ be able to do everything and so at this point its the most bloated language by a large mile.
How to program C++ correctly:
-C with classes means that you have the option to do classes and OOP, but not the obligation. Stop OOPing everything.
-Stop using stuff for which you dont know compiler behavior.
-Stop using smart pointers and actually learn memory management.
-Stop using templates for stuff you can do with macros.
-Avoid exceptions(biggest garbage of c++) and overloading(literally for brainlets)

but I have no idea what to do with it. I still have no idea what programming is.
