Celebrating 10 years of C++ User Gruppe Düsseldorf with Walter E. Brown - Correctly calculating min, max and more - Meeting C++ online
Slides: https://slides.meetingcpp.com
Survey: https://survey.meetingcpp.com

The C++ standard library long ago selected operator ＜ as its ordering primitive, and even spells it in several different ways (e.g., std::less).

This talk will explain why operator ＜ (and its aliases) must be used with care, in even such seemingly simple algorithms as max and min.

We will also discuss the use of operator ＜ in several other order-related algorithms, showing how easy it is to make mistakes when using the operator ＜ primitive directly, no matter how it’s spelled. (Of course, we will also present a straightforward technique to avoid such mistakes.)
