You want to call a function, not declare a variable.
Okay, so like this, maybe?
Code:
parseStringToMember(inputInfo);
I am getting an error at that line, though, so I'm guessing that is not right. Here is the error:
45 Assignment7.cpp `parseStringToMember' undeclared (first use this function)

Code:
newguy = new Whatever_type(appropriate things here);
rather than a separate pointer for each different type.
Okay, that makes sense. I think I get that. I am still getting a few errors, though many many less. I am getting these errors:
64 StaffMemberParser.h `Volunteer' has not been declared
84 StaffMemberParser.h `HourlyEmployee' has not been declared
90 StaffMemberParser.h `FullTimeEmployee' has not been declared
on the lines where I use the code you suggested above, though.
Here are the updated versions of my code:
Code:

// (add volunteers, full time employees, or hourly employees,
// compute their pay, search a member, list members,
// quit, display menu) to a user.
// Then it performs the chosen task. It will keep asking a user
// to enter the next choice until the choice of 'Q' (Quit) is
// entered.
#include <iostream>
#include <string>
#include <cstdlib>
#include <vector>
#include "StaffMember.h"
#include "StaffMemberParser.h"
using namespace std;
void printMenu();
int main()
{
char input1;
string inputInfo;
bool operation;
vector<StaffMember *> memberList;
printMenu(); // print out menu
do
{
cout << "What action would you like to perform?" << endl;
cin >> input1;
switch (input1)
{
case 'A': //Add Member
cout << "Please enter a member information to add:\n";
cin >> inputInfo;
parseStringToMember(inputInfo);
break;
case 'C': //Compute Pay
for (int j=0; j < memberList.size(); j++)
{
memberList.at(j)->computePay();
}
cout << "pay computed\n";
break;
default:
cout << "Unknown action\n";
break;
}
} while (input1 != 'Q' && input1 != 'q'); // stop the loop when Q is read
}
