The attached program is fine, but I need to create vectors for each
AcctExample object. I know that I can do the following:
vector<AcctExam ple> example which makes a vector of AcctExample objects
called example. Now, how do I activate the methods for each object?
Also, why are we replacing templates with vectors? (That was what the
assignment required. I don't get why we do this).
