Which of the following statement is correct about the program given below?

#include<iostream.h> 
class CuriousTabArray
{
    int array[3][3];
    public:
    CuriousTabArray(int arr[3][3] = NULL)
    { 
        if(arr != NULL)
        for(int i = 0; i < 3; i++) 
            for(int j = 0; j < 3; j++) 
                array[i][j] = i+j; 
    } 
    void Display(void)
    {
        for(int i = 0; i < 3; i++) 
            for(int j = 0; j < 3; j++)
                cout<< array[i][j] << " "; 
    }
};
int main()
{
    CuriousTabArray objBA;
    objBA.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.
