RE: Inheritance
 
C++ struct can not be inherited is FALSE. Here is what I coded:
struct A{int a;
void print(void) {
cout << "Hello from struct A: a = " << a << endl;
};
};

class B: public A{
public:
B(int arg1, int arg2) { b = arg1; a = arg2;};
int b;
void printA(void) {
cout << "Hello from Class B: b = " << b << " ;; a = " << a << endl;
};
};

int main(int argc, char* argv[]) {
   A a;
  a.a = 10;
  a.print();

  B* b = new B(20, 30);
  b->printA();
  return 0;
}
