The problem follows the patterns illustrated in the Actor4 example. It also extends the class relationship problem presented at the end of the previous chapter. As in the previous problem, all variable names, both members and parameters, are set by the problem and must be used consistently by your solutions.
class Person
{
private:
string name;
public:
Person(string n) : name(n) {}
friend ostream& operator<<(ostream& out, Person& me)
{
out << me.name << endl;
return out;
}
};
class Project
{
private:
char code;
public:
Project(char c) : code(c) {}
friend ostream& operator<<(ostream& out, Project& me)
{
out << me.code << endl;
return out;
}
};
class Record
{
private:
double salary;
public:
Record(double s) : salary(s) {}
friend ostream& operator<<(ostream& out, Record& me)
{
out << me.salary << endl;
return out;
}
}
class Employee : public Person // Inheritance
{
private:
Record myRecord; // Composition
Project* myProject = nullptr; // Aggregation
int id;
public:
Employee(string name, double s, int i)
: Person(name), myRecord(s), id(i) {}
friend ostream& operator<<(ostream& out, Employee& me)
{
(a)___________________________________
(b)___________________________________
(c)___________________________________
(d)___________________________________
return out;
}
};
Fill in the blanks to complete the Employee inserter function.
