Write a<< operator that allows for easy output of EvenNumbers to cout, a file, or any other stream. The proper operator is dclared as a friend to the class, you need to implement it.

Code:

#include using namespace std;

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

friend ostream& operator<<(ostream& theStream, const EvenNumber& number);

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);

cout << n1 << "----" << endl;

return 0;
