in "Overloading the Assignment Operator" page 418 at the bottom, the example member function returns "* this".
At the top of pg 419, Ivor says that we return a reference with this statement.
I'm a little confused. My understanding is that "this" is a pointer (to the object calling the function). So, if I use, "* this" am I de-referencing the this pointer, and therefore passing an "object" back?
VC++ help document, ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.VisualStudio.v80.en/dv_vclang/html/92e3256a-4ad9-4d46-8be1-d77fad90791f.htm
says
The expression *this is commonly used to return the current object from a member function:
return *this;
Sincerely,
Brian
