2. What should be passed in parameters when function does not require any parameters?

3. In which of the following we cannot overload the function?

4. Function overloading is also similar to which of the following?

5. Which of the following permits function overloading on c++?

6. What will be the output of the following C++ code?

    #include <iostream>
    using namespace std;
    void print(int i)
    {
        cout << i;
    }
    void print(double  f)
    {
        cout << f;
    }
    int main(void)
    {
        print(5);
        print(500.263);
        return 0;
    } 

7. What will be the output of the following C++ code?

    #include <iostream>
    using namespace std;
    int operate (int a, int b)
    {
        return (a * b);
    }
    float operate (float a, float b)
    {
        return (a / b);
    }
    int main()
    {
        int x = 5, y = 2;
        float n = 5.0, m = 2.0;
        cout << operate(x, y) <<"\t";
        cout << operate (n, m);
        return 0;
    } 

8. What will happen while using pass by reference?

9. What will be the output of the following C++ code?

    #include <iostream>
    using namespace std;
    int Add(int X, int Y, int Z)
    {
        return X + Y;
    }
    double Add(double X, double Y, double Z)
    {
        return X + Y;
    }
    int main()
    {
        cout << Add(5, 6);
        cout << Add(5.5, 6.6);
        return 0;
    }
