Casting double array to a struct of doubles

Question

Is it OK to cast a double array to a struct made of doubles?

struct A
{
   double x;
   double y;
   double z;
};

int main (int argc , char ** argv)
{
   do         


        

Answer 1

std::complex implementation of msvc use the array solution, and llvm libc++ use the former form.

I think, just check the implementation of the std::complex of your libc++, and use the same solution with it.
