[Cs3] comparing objects pointed to

[Mikhail Nesterenko]

CS3 students,

This is regarding code fragment:

    return accumulate(inFactories.begin()+1, inFactories.end(), *inFactories.begin(),
           [](CarFactory *a, CarFactory *b) {
                 return a->getNumCarsInProduction() < b->getNumCarsInProduction() ? a: b;
            }
           );



In
http://antares.cs.kent.edu/~mikhail/classes/cs3/Examples/AbstractFactory/CarFactory/CarTest.cpp

That we talked about in class. accumulate() is examining the array of
pointers to objects inFactories[] and returning a pointer that points
to the object with the smallest number of cars in production (least
busy).

There was a suggestion to use std::min() instead for
comparison. However, it is a bit tricky since we need to get pointers
to objets rather than objects themselves. If you guys have an idea as
to how to simplify the code, I'd be happy to listen.

Thanks,
