this pointer problem

hello.
i am having a problem with the this-pointer in the code below. for the
command: "MyFunctB(this)"; i am getting the following error:
error C2664: 'cTest::MyFunctB' : cannot convert parameter 1 from 'cTest *const ' to 'cTest'

whats the problem?
thanks.
V.K.

Code:

class cTest
{
public:
        cTest()
        {
                for (int i=0;i<3;i++)
                        dat[i] = rand()%43;
        }
        void MyFunctA ()
        {
                MyFunctB(this);
        }
        void MyFunctB (cTest a)
        {
        }
private:
   int dat[3];

};

int main()
{
        int i=0;

        srand(time(0));
        cTest A;

        A.MyFunctA();

        _getch();
    return 0; 
}

 

Code:

        void MyFunctA ()
        {
                MyFunctB(this);      [COLOR=Red]'this' is a pointer to a cTest[/COLOR]
        }
        void MyFunctB (cTest a)  [COLOR=Red]'a' is an actual cTest object[/COLOR]
        {
        }

Types have to match or be convertible. Why would you pass the 'this' pointer? It's automatically passed implicitly. Now you just have two copies.
