{
int x, y, z;
public:
Base()
{
x = y = z = 0;
}
Base(int xx, int yy = 'A', int zz = 'B')
{
x = xx;
y = x + yy;
z = x + y;
}
void Display(void)
{
cout<< x << " " << y << " " << z << endl; } }; class Derived : public Base { int x, y; public: Derived(int xx = 65, int yy = 66) : Base(xx, yy) { y = xx; x = yy; } void Display(void) { cout<< x << " " << y << " "; Display(); } }; int main() { Derived objD; objD.Display(); return 0; }

[A].The program will report compilation error.
[B].The program will run successfully giving the output 66 65.
