New Constructor Rules

• Nonvirtual base classes, only constructor is for immediate base class. But they can pass on to their bases.

  • class A{
  • int a;
  • public:
  • A(int n=0) {a = n;}
  • ...}
  • class B : public A {
  • int b;
  • public:
  • B(int m=0, int n=0) : A(n) : {b=m;}
  • ...}
