Description : Copies elements from range defined by [first, last), to another range ending at passed iterator.
Elements are copied in reverse order (last element is copied first), but the relative order is kept.
Example:
std::vector<int> origin {1, 2, 3};
// destination size is required to be at least the number of values to be copied
std::vector<int> destination(origin.size());
// Copy origin to destination, starting from the last element
std::copy_backward(origin.begin(), origin.end(), destination.end());
// destination is now {1, 2, 3}
for (auto value : destination) {
std::cout << value << " ";
}
