object defining within another class?

[Andrewcen16]

How would i go about getting the Person person_data in the private section of the second class;
Assume i have all the other member functions what bit of code or function would you use to set
person_data. I tried person_data()// constructor and it did not work so what do i do to define it

//Exercise P5.1. Implement all member functions of the following class:
class Person
{
public:
Person();
Person(string pname, int page);
void get_name() const;
void get_age() const;
private:
string name;
int age; // 0 if unknown
};
/*
Exercise P5.2. Implement a class PEmployee that is just like the Employee class except
that it stores an object of type Person as developed in Exercise P5.1.
*/
class PEmployee
{
public:
PEmployee();
PEmployee(string employee_name, double initial_salary);
void set_salary(double new_salary);
double get_salary() const;
string get_name() const;
private:
Person person_data;// i tried this person_data("Chris" ,44)  also defining a new Person object //and setting person_data equal to that new object, and that did not work either
// could someone please just show me how to do it, also explain it like i'm 5 please
double salary;
};

when posting code, post the relevant parts. There is no point in posting code that does not cause the error.
when getting an error, post the full message. Verbatim.

PEmployee::PEmployee(string employee_name, double initial_salary):
   person_data(employee_name, 0),
   salary(initial_salary)
{}

int main(){
   PEmployee foo("Chris", 3.14);
}

Your employee constructor doesn't allow you to set the age, may consider to include an extra parameter.
