Assume the existence of a Window class with integer data members width and height

Overload the $$ operator for the Window class$--$i$.$e$.,$ write an in$/$ine friend istream$-$returning function that accepts a reference to an istream object and a reference to a Window object and reads the next two values from the istream into the width and height members respectively.

Don't forget to have the function return the proper value as well.
