operator overloading

[over the top]

1-what is the difference or the pros of using dynamic allocated array (using new) over typical array?

2-in the next ex.
Date &Date::operator==(const Date & mydate1)
this binary operator takes two objects to compare
mydate1, mydate2
if i am using *this pointer in the body of the prescribed fuction, to whom is the pointer points mydate1 or mydate2?

1 - allocating memory dynamically is both slower and less safe than allocating on the stack, only allocate dynamically when you have to.

2 - the this pointer is a pointer to the current object being acted upon, if you've overloaded the equality operator on your Date class and you have two dates

Date date1(1,5,2010);
Date date2(15,3,2011);

then you do this

if ( date1 == date2 )

that is equivalent to

if ( date1.operator==(date2) )

and the this pointer would point to date1
