Which of the following statements regarding inline functions is correct?

class Bike
{
    Engine objEng;
};
class Engine
{
    float CC;
};

1. A reference is not a constant pointer.
2. A referenced is automatically de-referenced.

#include<iostream.h> 
class Tab
{
    public:
      int x;
};
int main()
{
    Tab *p = new Tab();

    (*p).x = 10;
    cout<< (*p).x << " " << p->x << " " ;

    p->x = 20;
    cout<< (*p).x << " " << p->x ;

    return 0;
}

#include<iostream.h> 
class CuriousTabSample
{
    public:
        int   a; 
        float b;
        void CuriousTabFunction(int a, float b, float c = 100.0f)
        {
            cout<< a % 20 + c * --b;
        } 
}; 
int main()
{   CuriousTabSample objCuriousTab;
    objCuriousTab.CuriousTabFunction(20, 2.000000f, 5.0f);
    return 0; 
}
