Output is 1,4,8,why c = 8,is not 1+4.If nothing in Base, sizeof(Base) = 1.and sizeof(A) = 1.In my understanding sizeof(A) is 4.why the result shows 1.
```
class Base{};
class A{
Base a;
};
class B{
int b;
};
class C{
Base a;
int b;
};
int main()
{
int a = sizeof(A);//1
int b = sizeof(B);//4
int c = sizeof(C);//8
cout<<a<<endl;
cout<<b<<endl;
cout<<c<<endl;
return 0;
}```
