Getting an iterator to an arbitrary index of a string

[James Aguilar]

Hey all,

Does anyone know how to get an iterator to an arbitrary location in a string (in
constant time)? This is the best I've been to do:

--- CODE ---

std::string::iterator iteratorForIndex(std::string &theString,
int position) {
return &theString[position];
}

--- CODE ---

Is there any more standard way to do it, again, in constant time?

a_string.begin() + arbitrary_location_index

This is the best I've been to do:

std::string::iterator iteratorForIndex(std::string &theString,
int position) {
return &theString[position];
}

See above.
