Trust me, it's not nearly as hard as some of the tutorials make it appear. Just learn pointers, they are invaluable concepts. Even if you move to higher-level languages you will still need pointer-like things otherwise you won't know how to structure your code well. I tried C# before C++ and I was dead-confused by reference types, turns out they are just pointers. Memory management: Your computer has two sections of memory: The Stack and The Heap. The stack is a section of memory where variables are essentially placed next to each other. Think of the stack like a literal stack of plates: you can only add to the top of the stack (adding a plate) or remove from the top of the stack (removing a plate). This keeps the memory consistent without causing any gaps or problems (if you tried removing a plate from the middle it would probably topple over). By default, all variables in C are allocated on the stack. This means all your variables are placed next to each other by default in the order they are declared. This is fast because the cpu processes data in chunks at a time. So when the CPU grabs one variable on the stack, it normally grabs some other variables alongside it for good measure too (at no extra cost). The only problem with the stack is that the variables cannot change size (because they all have to be next to each other). This is because if you imagine a variable growing in size on the stack, it might overwrite it's neighbours (not good). So instead, when you have a variable that you want to grow dynamically in size (like a list) you need to allocate it in a separate place so it doesn't overwrite its neighbours when it grows. This place is called the Heap, and it's essentially just a random "Heap" of variables. The variables do not need to be next to each other this time, so there can be some gaps and slower performance, BUT your variables can be resized on the heap. You might also need the heap if the size of your variable is not known at compile time. It's basically like a bookshelf vs a random pile of books, at least that's how I like to think of it. The bookshelf is more space efficient and faster, but the constraint is the books have to fit next to each other on the shelf. The "heap" of books is disorganised and slow, but you don't have the same fitness problems. You need to manage memory when you need to add or remove from the "heap", the stack is automatically done for you (variables are removed from the stack in the reverse order that they were added).

Hey t thank you for the video and can you make a video on should I learn C in 2024

I'd argue that you don't need to learn C++ if you only want to learn the underlying concepts that have been abstracted away in higher level languages. C has most of them, and can be learned in a day, with the main exception being RAII and other drop-dependent data structures. You do miss out on the STL, but you also don't have to uphold the invariants from the compiler - like making sure iterators don't accidentally get invalidated

Thank you for this comprehensive overwiew. 2:12 "Because C++ provides very little abstraction, ..." This is not completely true. C++ provides a wide range between no abstraction (for example direct memory access) and very high abstraction (string class, chrono, regex, data types in Standard Template like unordered_map).

Talking about buildsystem, CMake really should be the standard. Once I learned CMake it all clicked, I can use whatever library I want and compile my program without worrying about linking order, or any other problems without using a buildsystem. I think the only problem with CMake is a simple tutorial, just show the similarity with the compiler and it is easy. Yes CMake is very easy to use, just that first step wall is really a stupid thing I don't know why they can teach CMake effectively. And anything that teach C++ doesn't even mention what a buildsystem even is that is very stupid as well. I mean yeah back in the day people simply used compilers and then maybe a script then makefile, but it's 2024 now. Now I am not say CMake is the best, there are other build tools that are less verbose and works too but they don't give full control like CMake does. There are a lot of tools out there is kinda overwhelming as well for sure.

I found Rust to be hell for experimentation. You have to be very proficient in the language to make the program compile while managing different approaches to the problems you are dealing with. If you are not very good with the language usually it will have an inferir performance to Go (a much easier language), judging by some benchmarks i've seen. It's also pretty frustrating for learning data structures, which is a -1 for me because universities and college students will likely not use/study much the language (and so the ecosystem will not have as much young talent as it could). All in all i find the language fun, but it's more appropriate in systems where security and stability is critical. Also i find it's pretty good for tooling.

Yeah but its SOOOOOOOOOOOOOOO FAAAAAAAAARKINGGG VERBOSE... someclass::somesubclass::someotherclass::somemethod::blapblap->badabing->badaboop(std::vector x); Nah thanks even had enough. And then memory leaks holy moly! I didn't even attempt multithreading.. If I was still young but not anymore. Aint nobody got time for this!

AI generated tl;dr: The video discusses whether learning C++ in 2023 is a good idea. C++ is a versatile programming language with a wide range of applications, including game development, web APIs, mobile apps, data science, embedded systems, and more. It offers high performance due to its low-level nature and is used in mission-critical applications like finance. Learning C++ provides a deep understanding of programming concepts like memory management, pointers, and threading, which can benefit other languages. It's in demand in various industries, and its constant improvement through new standardized versions keeps it relevant. However, C++ has drawbacks: tooling can be challenging, and the language's complexity might lead to mistakes while learning. Ultimately, learning C++ can provide valuable insights into software engineering concepts.
