How can I debug constexpr functions in C++?

Debugging constexpr functions can be tricky since they are evaluated at compile time. You can use static assertions to check values.

What are static assertions and how do I use them?

Static assertions are compile-time checks that can help you validate conditions. You use static_assert(condition, message);.

Can you give me an example of a static assertion?

MagicBuddy
MagicBuddy

Sure! For example, static_assert(sizeof(int) == 4, "Integers must be 4 bytes"); checks if the size of int is 4 bytes.
