Do you believe it's from our C++ exam?

Caculate the value of i after each step
int x=2, y=x+30;

struct A{

 static int x;

 int y;

public:

 operator int( ){ return x+y; }

 A operator ++(int){ return A(x++, y++); }

 A(int x=::x+2, int y=::y+3){ A::x=x; A::y=y; }

 int &h(int &x);

};

int &A::h(int &x)

{

 for(int y=1; y!=1 || x<201; x+=11, y++)

 if(x>200) { x-=21; y-=2;}

 return x-=10;

}

int A::x=23;

void main( ){

A a(54, 3), b(65), c;

int i, &z=i, A::*p=&A::y;

 i=b.x; //.................................=A2=D9

 z=a.x; //.................................=A2=DA

 i=c.*p; //.................................=A2=DB

 i=a++; //.................................=A2=DC

 i=::x+c.y; //.................................=A2=DD

 i=a+b; //.................................=A2=DE

 b.h(i)=7; //.................................=A2=DF

}

and another one, write down the ouput of this program

#include <iostream.h>

struct A{A( ){ cout<<'A';}};

struct B{B( ){ cout<<'B';}};

struct C: A{C( ){ cout<<'C';}};

struct D: virtual B, C{D( ){ cout<<'D';}};

struct E: A{

 C c;

 E( ): c( ){ cout<<'E';}

};

struct F: virtual B, C, D, E{

 F( ){ cout<<'F';}

};

void main( ){

 A a; cout<<'\n';

 B b; cout<<'\n';

 C c; cout<<'\n';

 D d; cout<<'\n';

 E e; cout<<'\n';

 F f; cout<<'\n';

}
