Answer 1

Non-integral static member variables must be defined outside the class definition.
class EmployeeClass
{
// ...
static double iTotal_salaries;
static double iIndividualSalary;
static double iTotal_hours;
static double iTotal_OvertimeHours;
};
double EmployeeClass::iTotal_salaries = 0.0;
double EmployeeClass::iIndividualSalary = 0.0;
double EmployeeClass::iTotal_hours = 0.0;
double EmployeeClass::iTotal_OvertimeHours = 0.0;
