C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. This tag should be used for any question which requires knowledge or expertise with the C++ programming language. This is a general tag which is used for any of the C++ language standards (C++98, C++11, C++17, etc.). The question should identify the compiler being used, the operating system, and which of the C++ standards is being targeted.

Object Oriented Graph Hierarchy with Depth First Search
I would like to receive review on my code. It has only depth first search (DFS) and bidirected graph is the only member of the hierarchy. I added name member for the BiGraph to make it easier to debu …

A reader and its associated writer for disjoint value access
Easy of use:

Split a String On A Word By Words
I would extend this even further to have iterator support and other std::basic_string instantiations. The extension might not be worth it if the project is small and unlikely to change.

First stage of a complex calculator implementation in C++
Design
Since the name has complex in it, I'd always think about extensibility and flexibility.
I think this design is very fragile. I'd write something like infix to postfix notation converter and e …

Precision
float is usually a 32-bit floating point type. Perhaps you meant double? With C++23, you can use std::float64_t.

Multithreaded natural language text parser (Rev.3)
