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

#include<iostream.h> 
class PowerFinder
{
    public:
    void Power(int x = 1, int y = 1)
    {
        int P = 1, i = 1;
        while(++i <= y)
        {
            P *= x;
        }
        cout<< P << endl; 
    } 
};
int main()
{
    PowerFinder FP; 
    FP.Power(2, 6); 
    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.
