问一个关于this的问题，谢谢

下面这个小例子，出错
class.cc: In member function `void B::test()':
class.cc:22: error: request for member `a' in `this', which is of non-class type `B* const'
不太懂，而且去掉那个this就不出错了


#include <iostream>
#include <string>

using namespace std;

class A
{
   int a;
public:
   A(int initA):a(initA){}
   void print()
   {cout << a << endl;}
};
class B
{
    A a;
public:
    B(int b):a(b){}
    void test()
    {
       A* pA = &(this.a); //此处，去掉this不报错
       pA->print();
    }
};

main()
{
    B b(5);
    b.test();
}

为什么要加this？

openspace

&(this->a)
this是指针
