如果我们没有指定loop的次数为 compile-time constant 的话,代码就是这样: float dot(const float* x, const float* y, const size_t len){ float ret{}; for(auto i = 0; i < len; ++i){ ret += x[i]*y[i]; } return ret; } 这个for loop就会被完整地编译出来: dot(float const*, fl...
With C++14, constexpr functions can make use of most control structures available in general C++ code. So, instead of writing unwieldy template code or somewhat arcane one-liners, we can now just use a plain for loop: 使用C++14,constexpr函数可以使用常规C++代码中的大部分控制结构。因此,现在可...

Thanks for your feedback. We parsed the dump file you provided and found no useful information. There has a similar feedback:https://developercommunity.visualstudio.com/t/constexpr-in-c20-module-crashes-intell/10504045. Could you help us confirm that this is the same as y...
Ela pode conter instruções if e switch e todas as instruções de loop, incluindo for, for baseadas em intervalo, while e do-while. Pode conter declarações de variáveis locais, mas a variável deve ser inicializada. Deve ser um tipo literal e não pode ser static ou ...
It does however work if you declare begin and end outside the for loop like this auto begin_iter = vec.begin() + 1; auto end_iter = vec.end(); for (; begin_iter < end_iter; ++begin_iter) {}; It also works if you change to ...
for (int i=0; i<a; +=i) sum +=fac(i); // error : loop in constexpr function return sum; } 也如内联函数一样,在不同.h文件中,定义必须相同。可以认为constexpr函数是一个受限制的内联函数。 Constexpr函数不能写操作非局部函数。但是可以读操作非局部函数,可以使用作引用参数,但是也不能作写...
