Concepts in C++20: Revolution or Evolution
summary
C++20 concepts let templates state precise, compiler-checked requirements to produce targeted diagnostics instead of long error dumps. The talk demonstrates using predefined concepts like integral and floating_point plus requires-expressions, shows a sequence/container example that narrows algorithm overloads, and explains how constraining a function makes it a template and offers concrete overload and specialization patterns that improve intent, readability, and error messages.
