I have an STL map declared:
struct CLIENTSTRUCT
// Individual Department info
int clientKey; // ClientKey
int enrollKey; // Enrollment ClientKey
int guarantorKey; // Guarantor ClientKey
string clientName; // Client Name
} clientWork;
typedef map<int, CLIENTSTRUCT> CLIENTS;
CLIENTS clientData;
map<int, CLIENTSTRUCT>::const_iterator cIter;

I have seccessfully been able to populate the map with initial data
(via .insert), but I can't figure out how to _update_ the map objects.
Specifically, I need to modify rhe "enrollKey" and "guarantorKey"
elements of various objects after I use .find and the iterator cIter.
None of my references (nor google) points me in the right direction.
Please advise TIA

If you want to change the elements of the map, you should be using iterator,
not const_iterator:

map<int, CLIENTSTRUCT>::iterator cIter;

After that, you can write

citer->second.enrollKey = /* whatever */;
citer->second.guarantorKey = /* whatever */;

Or, alternatively:

CLIENTSTRUCT& cs = citer->second;
cs.enrollKey = /* whatever */;
cs.guarantorKey = /* whatever */;
