C++ Function Test – 3

1. 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;
    } 

2. 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;
