B+-Tree library

I was looking for suggestions on good implementations of in-memory B-Trees or B+-Trees that I could use for an in-memory database. Ideally implementations that include benchmarks. Any suggestions?

Best learning resources for an experienced developer in a different language?

Hello,

I'm looking for the best learning resources that anyone can recommend. I'm fairly experienced with C# and JavaScript but I have wanted to start learning C++ for game development.

Is there a good tutorial or something out there anyone can recommend to learn the C++ specifics and not just general programming logic (like loops, if statements, classes, etc)?

One thing I want the standard to remove from cpp

I want the standard to remove initializer_list from C++ std. It drove me nuts when trying to understand which c'tor gets called and when multiple template classes involved

using listOfPersons = std::vector<std::unorderedmap<std::pair<Person, int>, std::string>>;
listOfPersons persons {....};
std::vector<std::uniqueptr<Person>> p {makeunique<Person>(3), .....};

I tried to understand the implicit conversions and which c'tor would get called but I can't quite get it.

If the std could get rid of it , it would help the future versions of C++.

Sometimes old school is better. we can reserve and put things in vector like we used to. It's better to write a little verbose than using intializer\list imo

Small CPP compiler

I would like to know if there are small C ++ compilers (C ++ 11 or higher) like TinyCC but for C++, I have the impression that there are none or quite old ones ?

how to implement range constructor based on iterator

Hey, I have to implement template vector, based on the original vector class, and I have to implement a range constructor based on iterator.

This is the signature of the function:
template<class T, size_t StaticCapacity\>
template<class InputIterator>
vl_vector<T, StaticCapacity\>::vl_vector(InputIterator first,
InputIterator last);

You can see that T, staticCapacity are generic members.
can anyone have clue how to implement it?

thanks!

Simple C++ Console Game using Implementation of Linked List,Queue, or Stack Inquiry

Hello everyone! I'm still a newborn when it comes to programming so keep that in mind.I want to challenge myself to make a simple C++ Console Group Game with the implementation of Data Structure. Making a simple 1v1 game with the implementation with any one of the structure seems easy enough but I want to utilize any two of the data structure for the game ( i.e LL & Queue, Queue & Stack, LL & Stack, etc ). The problem is that I don't have any idea on any group game that would utilize any of these two data structure type. So here I am asking on the internet on any simple game ideas that is:

- A group game ( one group can be formed from more than one individual )

- Each group member would take turn

- Utilizes any of the two data structure ( LL, Queue,Stack )

To be fair, I don't know many games especially card games which is why I'm stuck on this task.

Hope somebody can help me out, I'd appreciate it :)

C++20 Modules build script (Python and g++)

Hello!
I have created a Python script for building projects using C++20 modules :
https://github.com/J-Vernay/cpp20.py/tree/main

It tracks dependencies between files (both #include and import) and compile them in order using appropriate g++ commands.

It also provides information display (list of source files and their module, dependencies...).

This can be handy to experiment C++20 modules while waiting for professional build systems to handle modules.
