I have a bunch of strings in a database that have in them a

int str_length = secondDelim - firstDelim;
Can someone give me a hint how to get this to work?
Not unless you give us a hint about the format of the string,
and what determines where you want to look to find the number.
Is my code way off, or is there a better way to do it?
Probably. Most of the time, for this sort of thing,
boost::regex is the simplest solution. Of course, once you've
got the numeric field, you'll have to use std::istringstream to
