Below program fails with heap excerption, print only
~Base
A::~A
Why? how to fix? I expect such output while deleting:
~Der
C::~C
B::~B
~Base
A::~A
class A
{
public:
A() { cout << "A::A" << endl; }
~A() { cout << "A::~A" << endl; }
};
class B
{
public:
B() { cout << "B::B" << endl; }
~B() { cout << "B::~B" << endl; }
};
class C
{
private:
int _c;
public:
C(int c = 1) : _c(c) { cout << "C::C(" << _c << ")" << endl; }
~C() { cout << "C::~C" << endl; }
};
class Base
{
private:
A a;
public:
Base() { cout << "Base" << endl; }
~Base() { cout << "~Base" << endl; }
};
class Der : public Base
{
B b;
C c;
public:
Der() : c(2) { cout << "Der" << endl; }
virtual ~Der() { cout << "~Der" << endl; }
};
int main()
{
Base* bp = new Der();
delete bp;
return 0;
}
