There is the C memcpy command, which you can use like this:

memcpy(destinationArray, sourceArray, sizeof(*destinationArray) * elementsToCopy);

There is also std::copy, which is a more C++ way of doing it:

std::copy(source, source + elementsInSource, destination);

Note that neither of these functions check to make sure that enough memory has been allocated, so use at your own risk!
