C++ 20 (2a) New Features - constexpr Extensions

The video tutorial covers the use of constant eval and constant init keywords in C++. It explains how static duration variables are initialized before the main function and the potential issues with static order initialization. The tutorial demonstrates how to use constexpr to ensure compile-time initialization and execution of functions. It also introduces the coneval keyword, which forces functions to execute at compile time, and discusses handling runtime parameters with constexpr. The video concludes with practical examples and solutions to common compilation issues.

How does the 'constexpr' keyword affect function execution time?

What is the role of the constant eval keyword in C20?
