Re: [Dev-C++] Help with vectors

[Michael C U. <mu...@cb...>]

You get the data from a vector the same way you get the data from an
array. So you can either use the subscript operator:

myvec[0] // 1st vector element
myvec[1] // 2nd vector element, etc.

Or you can use pointer arithmetic to iterate through the elements:

for (it = myvec.begin(); it != myvec.end(); ++it)
{
    cout << *it << endl;
}

Does that answer your question?
