Array size at run time without dynamic allocation is allowed?

Question

I\'ve been using C++ for a few years, and today I saw some code, but how can this be perfectly legal?

int main(int argc, char **argv)
{
    size_t size;

Variable Length Arrays (VLAs) are supported in the C++14 standard, which has recently been accepted, and is awaiting publication.
