Write a + operator that adds two EvenNumbers. The operator is declared in the class, you need to implement it after the class declaration.

#include using namespace std;

class EvenNumber { public: explicit EvenNumber(int n) { value = (n % 2 == 0) ? n : n - 1; //must be even }

EvenNumber operator+(const EvenNumber& other) const;

int getValue() const { return value; } private: int value; };

//Do not modify anything on or above the line below this //YOUR_CODE_BELOW

//YOUR_CODE

//YOUR_CODE_ABOVE //Do not modify anything on or below the line above this

int main() { EvenNumber n1(6); EvenNumber n2(2);

EvenNumber n3 = n1 + n2;

cout << n1.getValue() << endl; cout << n2.getValue() << endl; cout << n3.getValue() << endl;

return 0; }
