Question

C++ Assignment:

Create a class called FitnessMember that has only one variable, called name. The FitnessMember class should have a constructor with no parameters, a constructor with a parameter, a mutator function and an accessor function. Also, include a function to display the name.

Define a class called Athlete which is derived from FitnessMember. An Athlete record has the Athlete's name (defined in the FitnessMember class), ID number of type String and integer number of training days.

Define a class called Trainer whose objects are records for a fitness centers trainers. Derive this class from the class FitnessMember. A Trainer record has the Trainer's name (defined in the FitnessMember class) and a specialty as a String (for example, Weight, Aquatics, Cardio, Nutrition, etc.), and training session fee per day (use the type double).

Billing class has Athlete and Trainer objects as private data members. A Billing record will contain an Athlete object and a Trainer object.

Give all your classes a reasonable complement of constructors, and accessor and mutator functions.

Write a main test program that creates at least two Athletes, at least two Trainers, and at least two Billing records and displays the total trainer income from the Billing records. Your tests should test all the functions and constructors defined in your program. Your PDF file should clearly indicate what you are testing and the output.

Code:

#include <string>
#include <vector>
#include <iostream>

class FitnessMember
{
public:
std::wstring name;

virtual void setName(const std::wstring &name)
{
this->name = name;
}

virtual std::wstring getName()
{
return name;
}
};

class Athelete : public FitnessMember
{
public:
std::wstring ID;

Athelete(const std::wstring &name)
{
FitnessMember::name = name;
}

virtual void setID(const std::wstring &ID)
{
this->ID = ID;
}

virtual std::wstring getID()
{
return ID;
}
};

class Trainer : public FitnessMember
{
public:
std::wstring speciality;

Trainer(const std::wstring &name)
{
FitnessMember::name = name;
}

virtual void setSpeciality(const std::wstring &sp)
{
speciality = sp;
}

virtual std::wstring getSpeciality()
{
return speciality;
}
};

class Billing
{
public:
int amt = 0;

virtual void generateBill(Athelete *a, Trainer *t)
{
if (t->speciality.equalsIgnoreCase(L"weight") || t->speciality.equalsIgnoreCase(L"cardio"))
{
amt = 300;
std::wcout << std::wstring(L"BILL FOR : ") << a->name << std::wstring(L" IS : $") << amt << std::endl;
}
else
{
amt = 350;
std::wcout << std::wstring(L"BILL FOR : ") << a->name << std::wstring(L" IS : $") << amt << std::endl;
}
}
};

class AtheleteTest
{
static void main(std::vector<std::wstring> &args)
{
Athelete *a1 = new Athelete(L"XXX");
Athelete *a2 = new Athelete(L"YYY");

a1->setID(L"A123");
a2->setID(L"A456");

Trainer *t1 = new Trainer(L"AAA");
Trainer *t2 = new Trainer(L"BBB");

t1->setSpeciality(L"cardio");
t2->setSpeciality(L"nutrition");

Billing *b1 = new Billing();
Billing *b2 = new Billing();

b1->generateBill(a1, t1);
b2->generateBill(a2, t2);

std::wcout << std::wstring(L"TOTAL BILL IS : $") << (b1->amt << b2->amt) << std::endl;
}
};
