THIS USER ASKED 👇
Overload the + operator as indicated. Sample output for the given program:
First vacation: Days: 7, People: 3
Second vacation: Days: 12, People: 3
#include
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.
/* Your solution goes here */
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;
}
THIS IS THE BEST ANSWER 👇
FamilyVacation FamilyVacation :: operator + (int moreDays) {
FamilyVacation Copy = * this;
copy.numDays + = moreDays;
copy back;
}
Explanation:
You create a copy (which is simple because there are no clues in the class), then modify and return the copy.
