What will be the output of the following program?

#include<iostream.h> 
class CuriousTabBase
{
    public:
    int x, y;
    CuriousTabBase(int xx = 0, int yy = 5)
    {
        x = ++xx; 
        y = --yy;
    }
    void Display()
    {
        cout<< --y;
    } 
    ~CuriousTabBase(){} 
};
class CuriousTabDerived : public CuriousTabBase
{
    public:
    void Increment()
    {
        y++;
    }
    void Display()
    {
        cout<< --y;
    } 
}; 
int main()
{
    CuriousTabDerived objCuriousTab;
    objCuriousTab.Increment();
    objCuriousTab.Display();
    return 0; 
}

#include<iostream.h> 
class CuriousTabTeam
{
    int x, y; 
    public:
    CuriousTabTeam(int xx)
    {
        x = ++xx;
    }
    void Display()
    {
        cout<< --x << " ";
    }
};
int main()
{
    CuriousTabTeam objBT(45);
    objBT.Display();
    int *p = (int*)&objBT;
    *p = 23;
    objBT.Display();
    return 0; 
}

1. All function calls are resolved at compile-time in Procedure Oriented Programming.
2. All function calls are resolved at compile-time in OOPS.

#include<iostream.h> 
class CuriousTab
{
    int x, y; 
    public:
    CuriousTab(int xx = 10, int yy = 20 )
    {
        x = xx; 
        y = yy;
    }
    void Display()
    {
        cout<< x << " " << y << endl;
    } 
    ~CuriousTab()
    { } 
};
int main()
{
    CuriousTab objCuriousTab; 
    objCuriousTab.Display(); 
    return 0;
}

1. Once a reference variable has been defined to refer to a particular variable it can refer to any other variable.
2. A reference is not a constant pointer.
