Hacker News with Generative AI: String Manipulation

The best – but not good – way to limit string length (adam-p.ca)
Getting the length of a string seems simple and is something we do in our code every day. Limiting the length of a string is also extremely common in both frontend and backend code. But both of those actions – especially length limiting – hide a lot of complexity, bug-risk, and even vulnerability danger.

C++ String Conversion: Exploring std:from_chars in C++17 to C++26 (cppstories.com)
With the introduction of C++17, the C++ Standard Library expanded its capabilities for converting text to numbers with the addition of std::from_chars. This low-level, high-performance API offers significant advantages over previous methods, such as atoi and stringstream. In this article, we will explore the evolution of string conversion routines from C++17 through C++26, highlighting key improvements like constexpr support and enhanced error handling. Let’s dive into the details and see how std::from_chars can transform your approach to string conversion.
