serial numbers and databases
Hi guys. i need to write C++ program that detects duplicate serial numbers when entered in an existing database.
i work with an energy auditing firm, am tasked with making sure no energy auditor under me fakes a serial number, at least not one that has already been entered.

Use an std::set. The insert() function returns a pair<iterator,bool>, where the bool is false if the object already existed in the set.
