I have some variables in my program that are actually in a case statement. I have tried to get them to go to my class functions but I keep getting an error. I am suppose to get the variables to go to the SalariedEmployee and the Administrator class.

Answer 1

You never defined the constructors for SalariedEmployee or Administrator. Another answerer showed how you might define an implementation of a constructor that matches the signature in your existing definition, but in your code, the values of those variables are meaningless when you instantiate the emp1 object anyway, so you'd do better to just use a default constructor where you simply initialize most variables to 0:
SalariedEmployee::SalariedEmployee() :
wageRate(0), hours(0), netPay(0) {}
Note that I didn't bother initializing the string members; they automatically initialize themselves to "" (nothing).
Also, when you input data with getline(), you're not doing anything with it. Call one of your setter functions to pass the value that you read from getline(cin,...) to your emp1 object. Your option '3' looks like it's supposed to print whatever you entered previously, but you're not calling any "print" function. Your code has &Administrator::print; but that doesn't print anything. That statement evaluates to the address of the print method of the Administrator class, but you don't do anything with that address, so that statement does nothing. You might want to call emp1.print(), but emp1 is an object of type SalariedEmployee, not Administrator, and there's no print() method in the SalariedEmployee class.
Has your class talked about virtual inheritance (polymorphism)? If so, then you're probably supposed to be declaring a print() method in your SalariedEmployee class, and then defining an implementation of it in Administrator. So in class SalariedEmployee, you'll want this:
void print() = 0;
Then, in class Administrator, define it just as you've done. But when you create your emp1 object, be sure to make its type be Administrator because SalariedEmployee is just an abstract base class (since you only declared that objects of types inherited from SalariedEmployee should have a print() method, but print() isn't actually defined in the SalariedEmployee class).

Answer 2

You didn't implement the constructor of SalariedEmployee. You need something like:
SalariedEmployee::SalariedEmployee(string n, string s, double np,
double w, int h, string d)
: name(n),
ssn(s),
netPay(np),
wageRate(w),
hours(h),
department(d)
{
}
