Question

imagine that you are working for a logistics company operating out in the frontiers of
civilisation. Your boss wants to be able to run some basic analytics on some of the
routes that you currently support and wants you to implement some systems to help
her. However the current limitations of the legacy system prevent you from making
fundamental changes. Instead, you will need to use inheritance in order to achieve your
goal.
2.2.1
Vehicle Class
The vehicle class is the parent class of a derived class: locomotive. Their inheritance
will be public inheritance so reflect that appropriately in their .h files. The description of
the vehicle class is given in the simple UML diagram below:
2vehicle
-map: char**
-name: string
-size:int
--------------------------
+vehicle()
+setName(s:string):void
+getName():string
+getMap():char**
+getSize():int
+setMap(s: string):void
+getMapAt(x:int, y:int):char
+∼vehicle()
+operator−−():void
+determineRouteStatistics()=0:void
The class variables are as follows:
• map: A 2D array of chars, it will represent the map that each vehicle will have to
travel on.
• name: The name of the vehicle. For example, ”Frontier Express”.
• size: The size of the map as a square matrix.
The class methods are as follows:
• vehicle: This is the constructor of the class. It is simply the default constructor
with no additional features.
• getSize: This returns the size of the map as a square matrix.
• setName: This will set the name of the vehicle as received.
• getName: This will return the vehicle as set.
• getMap(): This will return the entire map variable.
• setMap(): This method receives the name of a text file that contains an ASCII map.
The map will be a square, equal number of rows and columns. The first line of the
map will have the number of rows. Every line after will contain a number of ASCII
characters that you must read into the map. This must allocate memory before
assigning the map.
• getMapAt: This receives two coordinates, an x and y, and returns what character
is located at those coordinates. If the coordinates are out of bounds, return ’:’.
• ∼vehicle: The destructor for the class. It has been made virtual.
• determineRouteStatistics: This function will be used to determine information from
the map based on requirements specific to the vehicle in question. As it stands, it
is made pure virtual.
3• operator−−: The overload of this operator will deallocate the memory allocated for
the map.
2.2.2
Locomotive Class
The description of the locomotive class is given by the simple UML diagram below:
locomotive
-supplyRange:int
---------------------------------
+locomotive()
+~locomotive()
+getSupplyRange():int
+setSupplyRange(s:int):void
+determineRouteStatistics():void
The class variables are as follows:
• supplyRange: This is the range, in terms of units (a unit being the distance between
one map coordinate and another) that the locomotive can travel on one trip. The
locomotive will require both coal and water in order to function and can only get it
at supply locations on the map which are marked by a ”*”. A supply location will
always be directly next to or adjacent to a railway, if one exists.
The class methods have the following behaviour:
• locomotive: The constructor of the class. It has no features beyond the default.
• ∼locomotive: This is the class destructor that will deallocate the memory assigned
by the class. It will also print out, ”locomotive removed”, without the quotation
marks and ended by a new line.
• getSupplyRange: Getters for the class variables.
• setSupplyRange: Setters for the class variables.
• determineRouteStatistics: This function needs to calculate the specific statistics for
the locomotive based on the map it is provided. The following key shows all the
specific elements that are pertinent to the locomotive:
1. *: Supply Stations. These supply the locomotive with coal and water.
2. O: Origin Points. This is where the trains will be expected to leave from.
3. E: Exit Points. This is where the train is expected to go towards.
4. #: Railroad. This is traversable tracks for the train. Locomotives can only
travel on the map where there is track laid.
The function will then determine a number of statistics and print them to the screen
in a neatly formatted way:
41. Distance: Distance from the origin to exit in units, where one ”#” is one unit
so a track of ”### ” is a 3 unit long track.
2. Number of Supply Stations: Determine the number of supply stations that
support the railway.
3. Journey Status: This will display: ”Viable” or ”Not Viable” depending on
whether the locomotive is capable of making the journey. To determine this,
calculate the distance from the origin to the exit as units. If the train can
reach this distance with its current supply distance, then the trip is viable. If
there is at least one supply station, then the trip will be viable. If not, it will
not be viable.
Display the information as follows:
Name: Frontier Express
Supply Range: 12 units
Origin Coordinates: 1,2
Exit Coordinates: 8,7
Distance: 16
Number of Stations: 2
Status: Viable
Finally an example small map is provided below:
O#--
-#*-
-#--
-##E
You will be allowed to use the following libraries: sstream,fstream, cstring, string,
iostream. You will have a maximum of 10 uploads for this task. Your submission must
contain vehicle.h, vehicle.cpp, locomotive.h, locomotive.cpp,map1.txt, main.cpp
and a makefile.

**************************************************
I tried my best to code as much as possible for this question, however this is a complete project itself. I completed the majority of Locomotive class, however the trip viability is part is still left, please post another question on which i will complete that.

please provide a upvote if you like my effort. Thanks!
