1. Rewrite the printInfo() functions of the Employee and Department classes by overloading the
put-to operator Operator<<.
C++
class Employee {
private:
string ID;
string name;
string jobTitle;
bool isManager;
string ID_of_Dept;
public:
void printInfo();
};
void Employee::printInfo() {
cout << "t" << ID << "|" << name << " | " << jobTitle << " | " << isManager << " | " <<
ID_of_Dept << "n";
}
class Department {
private:
string ID;
string name;
string loc;
string ID_of_manager;
vector listOfEmp_IDs;
public:
void printInfo();
};
void Department::printInfo() {
cout << ID << " | " << name << " | " << loc << " | Manager:" << ID_of_manager << endl;
cout << "List of emp IDs:n";
}

2. void main()
{
vector emp_list;
vector dept_list;
readEmployeesFromFile(emp_list);
readDepartmentsFromFile(dept_list);
//print out department info
for (int d = 0; d < dept_list.size(); d++) {
dept_list[d].printInfo();
//1. for each depertment get me the list of emp_IDs.
vector _listOfEmp_IDs = dept_list[d].get_listOfEmp_IDs();
//2. for each emp ID, get its index in the emp_list
for (int e = 0; e < _listOfEmp_IDs.size(); e++) {
int idx = findEmpIdxByID(/*which list to search in?*/ emp_list,
_listOfEmp_IDs[e]);
//3. print out the emp info
emp_list[idx].printInfo();
}
cout << "n-----------------------------------------------n";
}
}
