sizeof an object

Question

class A {}
int main {
A a;
cout << sizeof(a);

// outputs 1

Why is this the case?
Are we evaluating the object name as a char?

Answer 1

Each object is given different address. So to distinguish different objects, size of each empty class object is 1 byte i.e. minimum memory allotted as per C++ standards.
