Question

Overload the + operator as indicated. Sample output for the given program:

First vacation: Days: 7, People: 3
Second vacation: Days: 12, People: 3

#include <iostream>
using namespace std;

class FamilyVacation{
public:
void SetNumDays(int dayCount);
void SetNumPeople(int peopleCount);
void Print() const;
FamilyVacation operator+(int moreDays);
private:
int numDays;
int numPeople;
};

void FamilyVacation::SetNumDays(int dayCount) {
numDays = dayCount;
return;
}

void FamilyVacation::SetNumPeople(int peopleCount) {
numPeople = peopleCount;
return;
}

// FIXME: Overload + operator so can write newVacation = oldVacation + 5,
// which adds 5 to numDays, while just copying numPeople.

FamilyVacation FamilyVacation::operator+(int SetNumDays) {
int dayCount = dayCount + 5;
}

void FamilyVacation::Print() const {
cout << "Days: " << numDays << ", People: " << numPeople << endl;
return;
}

int main() {
FamilyVacation firstVacation;
FamilyVacation secondVacation;

cout << "First vacation: ";
firstVacation.SetNumDays(7);
firstVacation.SetNumPeople(3);
firstVacation.Print();

cout << "Second vacation: ";
secondVacation = firstVacation + 5;
secondVacation.Print();

return 0;
}
