Hi, I’m new to c++ and have understood that it will forever be the lifeblood of all programming — that’s why I chose it. Is there any course (or repository of knowledge in any way shape of form) paid or free that offers a comprehensive guide from beginner to advanced. Obviously absolute proficiency will take years of diligence but I still want to cover all of the nuances of c++. I have 4 days.
Thank you for your time.

it will be tough to get through any of those three in 4 days though

I have VSCode and have worked with Python before
storm oyster
we usually recommend visual studio for beginners, since just setting up VSCode can take days

What about Mosh’s ultimate c++ mastery course.
He’s a simple teacher, but not sure if what he offers is comprehensive enough
storm oyster
like there is a lot of stuff "around the language" that are entire subjects in and of themselves
I guess the question is what is your goal.
gusty plaza
Of course
storm oyster
being advanced C++ user will not happen in 4 days, sorry
gusty plaza
My goal is to establish a solid foundation in C++
If not intermediate
But I want to aggressively work towards HFT operations
HFT is the ultimate goal
storm oyster
maybe if you were coming from like Rust, C, Ada, or Fortran or something that might be possible. but there are whole concepts in C++ that take weeks to wrap you head around. like manual memory management and pointers. or native tooling and linking.

I’m a quick learner
No brain dog

But I guess the essentials is what I need
Mostly the ability to analyze and understand the code — why it’s formatted in this way etc.

yea the part of that labeled tutorial basics is pretty decent ^
you'll note it's like... a lot
it's just learncpp reorganized
gusty plaza
Yup
obsidian epoch
and that's just the very basics of the language
i wish learncpp touched on template metaprogramming
gusty plaza
Could you tell me about metaprogramming
And are there any HFT specialists here in low latency design?
thorny heron
i wish learncpp touched on template metaprogramming
does it not?
obsidian epoch
just class and function templates
storm oyster
Could you tell me about metaprogramming
metaprogramming is a way to program programming. in python this would be done with metaclasses. languages often have very different metaprogramming facilities, the two most common in C++ are define/preprocessor metaprogramming (inherited from C and generally avoided) and template metaprogramming.
obsidian epoch
preprocessor metaprogramming is also cool
storm oyster
And are there any HFT specialists here in low latency design?
this is a very specialized field and requires a lot of knowledge about stuff that is not C++ to even begin using C++ for it correctly.

Like binary? (0101110110001111000)
storm oyster
no
look if you are not versed well enough in python (the one language you claim knowledge in) to know what a metaclass is (nor what it is used for).... I do not think you have the basis of general programming knowledge you think you do
storm oyster
eh kinda, lua uses a similar structure. basically the object that is responsible for interpreting how the object works.

Finance, of course. But c++ is the lifeblood and the industry standard for HFT

could it be theoretically possible to absorb all of learncpp in 4 days?
storm oyster
Finance, of course. But c++ is the lifeblood and the industry standard for HFT
I more meant like... an understanding of networking and network protocols, an understanding of how modern computer architectures (ram, processors, interconnects) work, and an understanding of how operating systems function to manage memory and schedule tasks...
storm oyster

I mean you could probably read it all
and if you were some sort of polyglot savant with 20 years working in every language besides C++
maybe you'd get a decent chunk of it

I think I have a solid foundation in hardware because I disassembled my PC and rebuilt it from scratch and conducted extensive research on the upgrades. But yes there’s a lot more in memory management that I must learn
Honestly it doesn’t have to be 4 days
Realistically I have 4.5 days
I can extend it to 7
A week
thorny heron
better get started then 🙂

that's not even the beginning of what I am getting at...
like as a really basic question what is the performance difference between randomly accessed memory vs. in order accessed memory? what mechanisms are involved and how can we control them? what programming patterns cause each form of access?
none of which has to do with C++ (outside of "how do I do this in C++")

@gusty plaza Has your question been resolved? If so, type !solved :)
