net.cpp AND what on earth is vector<string>::const_ite

I am pretty unfamiliar with the network code, but when I search through net.cpp and net.h I don't see the line you're referring to in the code block.

What you see there is an iterator for a vector of strings. A vector<string> is like an array of strings, but a vector's a little more flexible than an array. An iterator is just a generic interface for looking at objects from a collection in order. So it makes sense to get the next string in the vector by doing ++i and to dereference the iterator to the string itself with *i. So if you have a vector that looks like this

["blah", "bleh", "bluh", "aaargh"]

and you do something like

Code:

vector<string> blah_string;
/* put the above values into blah_string*/
vector<string>::const_iterator i;
for( i = blah_string.begin(); i != blah_string.end(); ++i ) {
    cout << *i << endl;
}

it will print the values in order with each on a line.
