CMSC 202 Fall 02 Project 2 Solutions
Solution 1
Solution 1 demonstrates how to do all
prompting in main( ) and use mutators to store data into the Order
and Pizza objects. It has the most code of any of the three solutions.
Solution 2
Solution 2 overloads the input operators for
Order and Pizza. There is almost no code in main( ).
It stores the prices and the list of toppings in the objects. This is a
bit of memory waste (and a temporary pizza object must be instantiated in
order to print the list of pizzas), but it's a better solution than solution 1.
Given our current knowledge of C++, this is probably the best solution we
can write.
Solution 3
Solution 3 is an "advanced" C++ solution that uses
static data members and a static function. Static data members and functions
belong to the class instead of being duplicated in each object.
The advantage in this case, is that
the prices and toppings are not stored in each Order and Pizza object (so memory
is saved) and no temporary Pizza object is necessary to print the toppings.
Static data members and functions
are discussed in section 7.7 of the text.
