WebJan 17, 2011 · Red Alert pointed out that the code uses memcpy from array to array and std::copy from array to vector. That coud be a reason for faster memcpy. Since there is. v.reserve (sizeof (arr1)); there shall be no difference in copy to vector or array. The code is fixed to use array for both cases. memcpy still faster: Web3) copy constructor. Constructs the container with the copy of the contents of other, copies the load factor, the predicate, and the hash function as well.
