[완료]C++에서 객체 소멸후 멤버변수 값에 대해 궁금증이 있습니다.

#include <iostream>
using namespace std;
 
class AAA
{
public:
        int a;
public:
	AAA()
	{
		cout<<"empty object"<<endl;
                a = 100;
                ShowYourName();
	}
	void ShowYourName()
	{
		cout<<"I'm class AAA"<<endl;
                cout<<a<<endl;
                a++;
	}
};
 
int main(void)
{
	AAA *obj1 = new AAA;
        obj1->ShowYourName();
 
        delete obj1;
        obj1->ShowYourName();
	return 0;
}
 
출력결과:
empty object
I'm class AAA
100
I'm class AAA
101
I'm class AAA
0  //  <--- ?????
