assignmnt on classes

[samara]

it is a question on classes in order to get total charge of syrgery done medication taken, daily rate fee of hospital and then at last calculating the total charge of a patient.
i cannot complete the main program. the total charge is not being displayed. if i could get the correct code for the main program.

// account class//

class patientaccount{
float TotalCharge,daily_rate;
int Days;

public:
patientaccount();
void rate(float);
void UpdateDay();
void AddCharge(float);
float DisplayCharge();

};


// pharmacy.h//
class surgery:public patientaccount
{
float medication1(panadol),medication2(piriton),medication3(maxilase),medication4(novagesic-flu),medication5(zecid);

public:
pharmacy();
void updatepatient(int);
};


// class surgery //

class surgery:public patientaccount
{
float Surgery1,Surgery2,Surgery3,Surgery4,Surgery5;

public:
surgery();
void updatepatient(int);
};
// account cpp file
#include <iostream>
using namespace std;
#include "Account.h"
patientaccount::patientaccount()
{
TotalCharge=0;
daily_rate=0;
Days=0;
}

void patientaccount::rate(float a){
daily_rate=a;
}

void patientaccount::UpdateDay(){
Days+=1;
}

void patientaccount::AddCharge(float b){
TotalCharge+=b;
}

float patientaccount::DisplayCharge(){
return TotalCharge;
}

// pharmacy cpp file

#include "pharmacy.h"
#include <iostream>
using namespace std;

pharmacy::pharmacy(){
medication1(panadol)=100;//Values are random can be change
medication2(piriton)=200;

medication5(zecid)=500;
}

if(a=1)
AddCharge(medication1(panadol));
else if(a=2)

else if(a=3)
