Reference members cannot be bound to temporaries in a default member initializer (note; same rule exists for member initializer lists): struct A { A() = default; // OK A(int v) : v(v) {} // OK const int& v = 42; // OK }; A a1; // error: ill-formed binding of temporary...
作为Comate,由文心一言驱动的智能编程助手,我很乐意帮你解答关于“call to non-'constexpr' function”的问题。下面是对你的问题的详细回答: 1. 解释什么是constexpr函数 constexpr是C++11引入的一个关键字,用于指示函数或变量可以在编译时求值。如果一个函数被声明为constexpr,那么它的所有参数都必须是字面量常量...

I know it is a error, to call to non-constexpr function in constexpr. But it is still possible to do that? We are not allowed to use plenty of functions in constexpt? Reason: I want to use the std::bitset to do some bit checking in constexpr. But these functions are non const...

One noteworthy thing about the above example is that we do not have to dynamically allocate the m_array member variable! This is because for any given instance of the StaticArray class, size must be constexpr. For example, if you instantiate a StaticArray<int, 12>, the compiler replaces ...
