Why use iterators over ints?

[kong288]

Why is it preferred to use:

for (std::vector<int>::iterator it = myvector.begin() ; it != myvector.end(); ++it)
{
    std::cout << ' ' << *it;
}

over:

for(int i = 0; i < myvector.size(); i++)
{
cout << myvector[i];
}

?

in your example, i wouldnt prefer to use iterators.
