Multi-Paradigm Programming with Modern C++ - Compile-Time Evaluation Using constexpr

The video tutorial explains the concept of compile-time evaluation and its benefits, such as improved performance and code readability. It introduces the 'constexpr' keyword, which allows functions and variables to be evaluated at compile time, enabling their use in static assertions. The tutorial demonstrates practical applications of 'constexpr', including converting degrees to radians and calculating cosine values using Taylor series. It also covers the creation of compile-time arrays for optimization, highlighting how precision affects executable size.
