一段使用C++的奇怪代码

linjiangbin02// Dev.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

class A
{
public:
int a;
void ak()
{
int t = 0;
this->a = 9;
}
void Release()
{
delete this;
}
};

class B
{
public:
int b;
};

class C :public B,public A
{
public:
int c;
void ak()
{
int t = 0;
}
};

int main()
{
C* p= new C;

p->ak();
p->Release();

return 0;
}
