simple string question...

Hi all,

I wrote a function which has a parameter of "string". When I send the
string, can I do like the below?

void Show::caller(void)
{
string str = "This object's address is " << this;
}

void Show::show_message(string str)
{
cout << str;
}

I got errors (obviously).

What would be the solution for this? Any suggestions?

Best regards,
Alex
