In the above c++ code (answer) (couldnt write it as it is long), classes for the calculation of CO2 emissions were programmed, and you will certainly have noticed several duplications of members. In this task, the program shall be modified on the basis of single inheritance and dynamic binding as well as other items be added.
- Define a C++ enumeration (as an enum struct ) with the following four values: once , daily , weekly , monthly .
- For this enumeration, define an overloaded output operator , which, depending on the enumeration value daily , weekly , monthly , and otherwise, does not write anything to the character output stream reference passed as a parameter. Also define an overloaded input operator >> for enumeration values (see also examples below).
- Define an abstract class named CO2Emissionwith the following members:
- private pointer attribute named next to build up a list of CO2 emissions .
- public standard constructor initializing the pointer attribute to a C++ null pointer.
- public virtual destructor writing " destructor CO2Emission : done" onto the standard character output stream .
- public member function named get_next without parameter returning the value of the pointer attribute.
- public member function named set_next with a pointer of type CO2Emission as parameter , which sets the value of the pointer attribute to the parameter value.
- Public pure virtual member function named get_co2 without parameter and with a floating point number as return which has to be implemented in the derived classes.
- public pure virtual member function named print without parameters and without return Which has to be Implemented in the derived classes .
- Define an abstract class with name Transportation publicly inherited from class CO2 emissions with Following members:
- private attribute named km of type floating point number for the number of kilometers driven .
- private attribute named frequency of above defined enumeration type Frequency , how often a transport takes place .
- public standard constructor in whose body , as in the example below, the value for the kilometers traveled and the frequency (by input operator defined above) shall be read from the standard character input stream and stored in the two attributes.
- public constructor with two parameters for initializing the two attributes with the values of the parameters - the parameter for the frequency shall be a default parameter with default value once from above defined enumeration data type Frequency .
- public virtual destructor writing like in the examples below " destructor Transport: " , the frequency, the traveling distance value and " km done" onto the standard character output stream .
- private member function named get_co2_pkm without parameter and with a floating point number as return which has to be implemented in the derived classes .
- public member function named get_co2without parameters and with a floating point number as return. In the body, the product of the kilometers driven and the respective emission value for one kilometer (via a call to the previously defined member function) and a number representing the frequency (once => 1, daily => 365, weekly => 52 , monthly => 12) shall be calculated and returned.
- public member function with name print without parameter and without return. In the body, as in the example below, the string "transport" and the frequency (by above defined output operator) shall be written onto the standard character output stream, the kilometers driven with one decimal place, in round brackets the CO2 emission value per person-kilometer with three decimal places and the calculated CO2 emission with one decimal place (call the previous member function suitably).
- Modify your class with name Bus and derive it publicly from the class Transport . Delete the attribute km and the member function get_co2 . Modify the two constructors calling the respective constructor of the superclass so that their functionality remains the same. Also modify the member function print so that it calls the function print of the direct superclass after outputting "local bus" or "long distance bus" depending on the value of the Boolean attribute. Add a public virtual destructor that outputs " destructor Bus: "and calls function print (see example below).
- Modify your class with name Car and derive it publicly from the class Transport . Delete the attribute km and the member function get_co2 . Modify the two constructors calling the respective constructor of the superclass so that their functionality remains the same. Also modify the member function print so that it calls the function print of the direct superclass after outputting "passenger car" . Add a public virtual destructor that outputs " destructor Car: " and calls function print (see example below).
- Modify your class with name Flight and derive it publicly from the class Transport . Delete the attribute km and the member function get_co2 . Modify the two constructors calling the respective constructor of the superclass so that their functionality remains the same. Also modify the member function print so that it calls the function print of the direct superclass after outputting "flight" . Add a public virtual destructor that outputs "destructor Flight: done" like shown in the example below.
- Modify your class with name Train and derive it publicly from the class Transport . Delete the attribute km. Modify the two constructors calling the respective constructor of the superclass so that their functionality remains the same. Modify the member function get_co2 suitable so that the same named function of the superclass is called in it and a one-way or a return journey is still taken into account in the calculation. Also modify the member function print so that it calls the function print of the direct superclass after outputting "one way" or "return" and "local train" or "long distance train" . Add a public virtual destructor that outputs " destructor Train: "print (see example below).
- Modify your class with name Cruise and derive it publicly from the class CO2Emission . In the constructors, call the standard constructor of the superclass and add a public virtual destructor to the class that outputs " destructor Cruise: " and calls function print (see example below).
- Define an class with name CO2Footprint with following members:
- private attribute named name of type C++ string to whom the carbon footprint is assigned.
- private pointer attribute named emissions in which to point to the head of a list of CO2 emissions.
- public constructor initializing the name to the value of the parameter and the pointer attribute to a C++ null pointer.
- public destructor writing "destructor for CO2Footprint for" , the name and " started... " onto the standard character output stream , then in a loop deletes all list items on the heap one by one and writes "destructor CO2Foodprint done" onto the standard character output stream at the end (see example below).
- public member function named get_name without parameter returning the value of the same named attribute.
- public member function named add with a pointer of type CO2Emission as parameter that inserts the object pointed to at the top of the list of CO2 emissions inserting the pointed to object at the head of the list of the carbon emissions.
- public member function named get_sum_co2 without parameter and with a floating point number as return. In the body the carbon emissions of all list elements shall be added and this sum value get returned.
- public member function named print without parameter and without return. In the body, the name shall be outputted after the string "CO2 FOODPRINT FOR: " , the message print shall be sent to all objects in the list, then the sum of all CO2 emissions shall be calculated and written onto the standard character output stream after "TOTAL CO2 EMISSIONS: " in the units kg and tons, each with 1 decimal place (see example below).
- Modify function main as follows : _ When the program ends, the C++ runtime system automatically calls the destructor for the object f , which deletes all objects in the list of CO2 emissions, thus triggering the destructor outputs as in the example below./ If the program ends, the C++ runtime system automatically calls the destructor for the object f , which deletes all objects in the list of carbon emissions and thus triggers the outputs of the destructors like shown in the example below.
- delete everything everything except the definitions of the five pointer variables b2, c2, h2, f2 , t2 and their initializations pointing to new objects in heap.
- define a variable of type C++ string, after a user guidance read a name into it from standard character input stream, and define and initialize an object f (not a pointer *f) of type CO2Footprint with this name (see example below).
- send a message add to the object f with the pointers b2, c2, h2, f2 , t2 as parameters.
- write a small menu with the menu items shown in the example below. For each of the defined non-abstract CO2 emissions subclasses, a new object should be created on the heap using the standard constructor and added to the CO2 footprint object f . Under menu item (p) the message print is to be sent to the object f ./ write a small menu with the menu items shown in the example below. For each of the defined not abstract CO2 emission subclasses a new object shall be created on the heap using the standard constructor and be added to the CO2 footprint object f . Under menu item (p) the message print shall be sent to the object f
If the program ends, the C++ runtime system automatically calls the destructor for the object f , which deletes all objects in the list of carbon emissions and thus triggers the outputs of the destructors like shown in the example below.
