sizeof（class）问题

#include <iostream>
using namespace std;
class A
	{};
class B
	{
	void func(){}
			};
class C
	{
	virtual void func(){}
		};
class D :public C
	{
		
	};
class E :public C
	{
	char c;
	void func(){}
	};
class F:virtual public A
	{};
void main()
{
int a=sizeof(A);
int b=sizeof(B);
int c=sizeof(C);
int d=sizeof(D);
int e=sizeof(E);
int f=sizeof(F);
cout<<a<<b<<c<<d<<e<<f<<endl;
}
