$21\mathrm{.}3$ Lab $2-$ Classes Part $2$

The next class you're going to write and test is the Showroom. This class will be storing Vehicle objects, so you can just bring in your code from Part $1$ and reuse that here.

Showroom

The Showroom class is a bit more sophisticated. Its purpose is to store a collection of Vehicle objects.

Each Showroom that you create could have a different number of Vehicles $($depending on its size$),$ so for

this assignment we$$ll use a vector. Your Showroom should contain variables for the following:

$$ The name of the Showroom

$$ A vector to store Vehicle objects

$$ A maximum capacity of the showroom $($we don$$t want to add Vehicles beyond this limit$)$

In addition, you should create the following functions:

Function Reference

Constructor Same as all constructors! Initialize class member variables

GetVehicleList Return the vector objects, so other code can access it

AddVehicle If the Showroom is already full $($numberOfVehicles $==$ capacity$),$ then you should

print out "Showroom is full! Cannot add $2015$ Mazda Miata" $($this will use

the GetYearMakeModel$()$ function from the Vehicle class$)$

If there is space in the showroom, add the pass$-$in Vehicle to the class$$ vector.

Vector objects can be expanded with the push$\_$back$()$ function.

ShowInventory Show all vehicles in the showroom, using the Display$()$ function of each vehicle

GetInventoryValue Sum up the prices of all vehicles in the showroom and return that value
