how to write contents for linked list to a file

I have a write function which im using to write the contents of a list to a file. The list contains only numbers.

list<int>::iterator pos;
    for (pos = listStorage.begin(); p开发者_运维问答os != listStorage.end(); ++pos)
    {
        out << *pos << endl;
    }
    return out;

I am getting an error on compilation;

error C2679: binary '=' : no operator found which takes a right-hand operand of type 'std::list<_Ty>::_Const_iterator<_Secure_validation>' (or there is no acceptable conversion)

Can anyone help? Thanks

I'm fairly certain this is a const issue. Is your listStorage object declared as const? If so, you need to declare your iterator as

const list<int>::iterator pos;

Rather than an explicit loop, I'd use an algorithm:

std::copy(listStorage.cbegin(), listStorage.cend(),
          std::ostream_iterator<int>(out, "\n"));

This will probably prevent the problem you're seeing, and incidentally clean up the code and almost certainly run faster as well (though the speedup with come from using "\n" instead of endl).
