Simple c++ inheritance not working via input from a keyboard - non class type error in main()?

Guys please im confused, this is just a simple inheritance in c++ OOP. All i need is an input from a keyboard but nothing works. It works when i provide the data in the class object but not when i need an input...? It will work when i try PTEmployee p1(1010,"shakespeare",300) & simplify code, but i need to test it with a keyboard input;

#include<iostream>
using namespace std;

class Employer 
{
private:
    int eId;
    string eName;

public:
    Employer (int id=1, string name="no name")
    {
         setEmpID(id);
         setEmpName(name);
    }
     Employer(Employer &e)
    {
        eId=e.eId;
        eName=e.eName;
    }
void setEmpID(int id){eId=id;}
void setEmpName(string name){eName=name;}

int getEmpID(){return eId;}
string getEmpName(){return eName;}
};

class FTemployee:public Employer 
{
private:
int salary;

public:
FTemployee (int id, string name, int sal):Employer(id, name)
{salary=sal;}

int getSal(){return salary;}
void setSal(int sal){salary=sal;}

};

class PTemployee:public Employer 
{
private:
int wage;

public:
PTemployee (int id, string name, int wg):Employer(id, name)
{wage=wg;}

int getWage(){return wage;}
void setWage(int sw){wage=sw;}

};

int main()
{

FTemployee f1();
PTemployee p1();

//FT object
cout<<"What is your Employee ID: ";
cin>>f1.setEmpID();

cout<<"Name is your name please?: ";
cin>>f1.setEmpName()

cout<<"Please enter your Salary: ";
cin>>f1.setSal();

cout<<"Employee ID: "<<f1.getEmpID()<<endl;
cout<<"Name: "<<f1.getEmpName()<<endl;
cout<<"Salary: "<<f1.getSal()<<endl;

cout<<endl<<endl;
//PT object

cout<<"What is your Employee ID: "<<endl;
cin>>p1.setEmpID()<<endl;

cout<<"Name is your name please?: "<<endl;
cin>>p1.setEmpName()<<endl;

cout<<"Please enter your Wages: "<<endl;
cin>>p1.setWage()<<endl;

cout<<"Employee ID: "<<p1.getEmpID()<<endl;
cout<<"Name: "<<p1.getEmpName()<<endl;
cout<<"Wages: "<<p1.getWage()<<endl;

    return 0;
}
