#include <iostream>
using namespace std;
 
class Empty
{};
 
 
class Derived : virtual public Empty
{
    char c;
};
 
int main()
{
    cout << "sizeof(Empty) " << sizeof(Empty) << endl;
    cout << "sizeof(Derived) " << sizeof(Derived) << endl;
 
 
    return 0;
}

为什么尺寸即将到来8我觉得它应该是9,
如果我将’c’声明为整数,那么它也是8
你请给我解释逻辑
