Template with Inheritance C++ - c++

Question

Using inheritance and templates, Ive to sort by name an array of employee information. I got three classes, Payroll, SimpleVector and SortingVector. Payroll contains all the user info attributes, SimpleVector creates a dynamic array of type Payroll to store all the user info. Now do SortingVector class is in charge of sorting the array by names. But I keep getting many different errors whenever I tried to fix a previous error.
Posting now each class:
Payroll class

#include<string>
#include<vector>
using namespace std;
class Payroll {

int empNumber;
string name;

double grossPay;
int *aptr;
int arraySize;
public:

Payroll();
Payroll(const Payroll & aPayroll);
~Payroll();
//Mutators
void setVector(Payroll &aPayroll);

Answer 1

SortingVector<Payroll> temp(); is not parsed as you expected (vexing parse), you want:
SortingVector<Payroll> temp;
or
SortingVector<Payroll> temp{}; /* since C++11 */
