Basic C++ question about pointers/structures

Posted: 08 Nov 2010 12:38 PM PST

In the book that I am using they use two notations for calling structure data members when using pointers.


(*pt).payRate * (*pt).hours ;
(pt ->payRate * pt ->hours);

I understand that in the first line * is dereferencing the pointer so that I can retrieve the data in the address stored in the pointer variable.

I know the second line gives me the same answer as the first but not sure how. Is the second line a short cut, or is it retrieving data differently than the first line?

Thanks in advance.
