What is the output of this program?

#include <iostream&f=gt;
    using namespace std;
    class Num
    {
        private:
        int Values[15];
        public:
        int& operator[] (const int Val);
    };
    int& Num::operator[](const int Val)
    {
        return Values[Val];
    }
    int main()
    {
        Num Object;
        Object[10] = 6;
        cout <<  Object[10];
        return 0;
    }

1. 15
2. 10
3. 6
4. Compilation Error
5. None of these

Correct Option: C

In this program, We are getting the values and returning it by overloading the subscript operator.
