cant access a private member using friend

[adamiuy]

i cant access (name)
here is the code:

class employee{
public:
    void setName(string,double);
    void print();
    employee();
    employee(string,double);
protected:
    double hourRate;
private:
    string name;
friend class partTimeEmp;
  friend istream& operator>>(istream& in,partTimeEmp& a);


};
 class partTimeEmp :public employee
 {
 public:
     void setInfo(string,double,double);
     void print();
     double calculatePay();
     partTimeEmp();
     partTimeEmp(string,double,double);
 private:
    double workHours;
  friend istream& operator>>(istream& in,partTimeEmp& a);

 };
 istream& operator>>(istream& in,partTimeEmp& a)
 {
     cout<<"enter name :"<<endl;
     in >> a.name;
     cout<<"enter hourly rate:"<<endl;
    in >> a.hourRate;
    cout<<"enter work hours:"<<endl;
    in >> a.workHours;


     return in;

the errors:
error: 'partTimeEmp' has not been declared
error: 'std::__cxx11::string employee::name' is private
error: within this context

The class itself doesn't need to be a friend here (at least, within your example), so you can remove line 11.

To fix this, add
class partTimeEmp;
before the definition of class employee { ... };
