问Constexpr单元测试和断言ENC++17 不仅增强了现有特性，还引入了一些全新的编程工具，极大地提升了代码的效率和表达力。在这篇文章中，我们将深入探讨 C++17 中与 constexpr 相关的三个重要特性：constexpr 的扩展用法、if constexpr 和 constexpr lambda。这些特性不仅改变了我们对编译时计算的理解，还为模板编程和...

Because thenoexceptoperator always returnstruefor a constant expression, it can be used to check if a particular invocation of a constexpr function takes the constant expression branch: constexprintf();constexprboolb1=noexcept(f());// false, undefined constexpr functionconstexprintf(){return0;}...
Defines an expression that can be evaluated at compile time. Such expressions can be used as non-type template arguments, array sizes, and in other contexts that require constant expressions. If you have a constant integral variable that isconstinitialized, or enumeration value, then it can be ...
(This is because the tool cannot check if the hash code is stable between different JVM executions.) Methods: The annotated method will be callable by the inliner tool. If it is an instance method, then it will be called only if an appropriate instance can also be reconstructed by the ...
Otherwise, you’d need to have separate functions (a function with a constexpr return type, and a function with a non-constexpr return type). This would not only require duplicate code, the two functions would also need to have different names!
