since most of the people didn't read the book or they don't remember what task 2-6 are. Would you care to post what you are trying to do?
Sorry, the function setbits(x,p,n,y)
Return x with the n bits that begin at position p to the rightmost n bits of y, leaving the other bits unchanged

Basically extracting the n bits from the position p in y

Return x with the n bits that begin at position p to the rightmost n bits of y, leaving the other bits unchanged
return x | ((1<<p)-1) - ((1<<(p-n))-1);
((1<<p)-1) gives you p ones

"learn C++" or "learn C with std::cout, with introduction to classes are on chapter 52"?

This site segregates a lot of YouTube videos (around 750) on C++ into sections and topics. You can choose a topic and browse the video collection there.

Assignment
In this assignment, you will be implementing a Queue using the Stack data structure in C++. A Queue is an abstract data type that follows the First-In-First-Out (FIFO) principle, while Stack follows the Last-In First-Out (LIFO) principle. You will use two stacks to implement the Queue, where one will be used to enqueue elements, and the other will be used to dequeue elements.
Instructions:
1. Use the Stack data structure (with push, pop, and top operations) that we implemented in the lecture.
2. Implement the Queue data structure using two stacks, Stack1 and Stack2. Stack1 will be used to
enqueue elements, while Stack2 will be used to dequeue elements.
3. Implement the enqueue operation to add an element to the Queue. In this operation, you will push the element onto stack.
4. Implement the dequeue operation to remove the first element from the Queue. In this operation, you will pop the elements from Stack.
5. Implement the front operation to return the first element of the Queue without removing it. In this operation, you will return the top element of Stack.
6. Implement the empty operation to check whether the Queue is empty or not and the full operation to check whether the Queue is full or not.
7. Test your implementation with several test cases, including the case where the Queue is empty, and the case where the Queue is full
Submit your implementation along with the test cases and a brief explanation of your implementation and the time complexity of each operation.
Note: You are not allowed to use any built-in data structures or functions related to Queue or Stack, such as queue or stack, in your implementation

Check out the resources section of this group.
A book on this specific topic has been mentioned in the recommended list.
FYI, the book name is Windows via C/C++

I'm trying to use crtp instead of pure virtual functions
but am having trouble initializing the array.
For example:
ToolBase *tool_arr[3] = {&pen, &pencil, &brush}.
If I want to use crtp to implement this, I still need to use virtual functions, so I feel like I'm back to square one.
Here's the code
https://pastebin.com/rxYU5XxU
Update :
I've been told that type list is one solution here 🤔 is it correct

Your code uses CRTP , virtual functions et al but it seems like they are all forced into a big chunk of code in an effort to get them to work together.
You should instead read up on TypeErasure and try using that instead. This encapsulates away CRTP and the requirement of deriving from a common base class away from your client code. For ex using Type Erasure, the classes Pen, Pencil et al don't have to derive from a common base or a CRTP base. You could do this behind the scenes in a TypeErasureHolder class.
Using type Erasure also would help with duck typing meaning you don't need virtual functions. As long as the interface provides for a method with the necessary parameters, you can call it. If such a method is not present then it will be a compile time error.

Is there any benefit of using c++ over any other widely adopted middleware development language by security POV?
Manuel
The main benefit is in general performance, then there can be other project specific benefits: C++ developers available, compatibility, maintenance and integration in an existing C++ codebase etc.

Good recommendation. But the truth is that cppreference is not beginner friendly

When you say widely adopted do you mean in general or in your organization? If it is the latter then it makes sense to stick to what is being used if you are not the one in a position to decide if a shift is required.
If it is the former then you have to weigh the consequences. If something has been widely adopted, then it is so for a reason primarily support, issue addressing, available libraries and so on. Before moving to C++, you must see if all these issues are non issues and then consider moving. From a security point of view, coding in any language can expose security loopholes (C and C++ even more so). This is not a problem with the language per se but the programmer's problem. If this is not something you want to burden your programmers with, then a language like Rust may help but only to an extent. Even with Rust you can write an idiotic encryption algorithm that can be easily broken. So in a nutshell, security is a programmer's headache and languages/compilers can only help to an extent.

I think Klimi suggested cppreference because the user asked for C++ documentation and not a beginner friendly learning resource. Documentation of a language is usually terse and there is no escaping that.
Anyway I also suggested books he/she can read to learn C++ if that is what he/she wanted and asked for documentation by mistake.

Geany, it's a good one, too.
Another I used sometimes is Codelite, created to use with Cmake, you can take a look and evaluate it :)

//should work for both std::vector and std::array too... And other iterables objects

i get compile error, and visual studio actualy tell me there is one, it basicallly doesn't allow me to use T::value_type inside the function declaration, how can i bypass this?
Danya🔥
typename T::value_type
Pavel
where should i put this
Add typename before the type that is dependent on the template argument
Pavel
This basically says to the compiler "hey I know this type is not yet known during first step of the compilation, but I promise the actual type will have it"

Actually this is not the case.
The typename keyword says this is a typename and to treat it as such. By default the compiler assumes it is not a typename and T::value_type will be treated as a static member and not a typename. The typename is a hint to the compiler to treat it as a typename rather than a static member

Hm, interesting, I always thought it is to allow to use not yet introduced names
Pavel
Especially because this kind of things worked (at least before) with MSVC where they didn't have this multi-step template compilation
Anonymous

No. It is to help the compiler disambiguate between type names and static members. The default behavior of compilers is to treat scoped names of classes as static members
Anonymous

Not sure about this but if Visual Studio did this then it is a violation of the standard

I prefer vim plugin on top of other IDEs such as vscode or Clion, rather than hacking ide functionality on top of the vim itself.
