Question

A10 – Overloaded Hospital

"Overloaded Hospital", page 371, Number 15

Write a program that computes and displays the charges for a patient;s hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient, the following data should be entered by the user:

The number of days spent is the hospital

The daily rate

Hospital medication charges

Charges for the hospital services (lab test, etc.)

The program should as for the following if the patient was an out-patient:

Charges for the hospital services (lab tests, etc.)

Hospital medication charges

The program should/will use two overloaded functions (defined in this chapter!) to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other functions accepts arguments for the out-patient information. Both functions should return the total charges and of course you will print these tot he screen.

Input Validation: Do not accept negative numbers for any data.

Please do not copy and paste someone elses code. It would really be awesome if someone explained the code to me.

=================================================================

#include<iostream>
#include<string>

using namespace std;

// function accepts the message to be displayed
// function keeps on prompting user for a non-negative number
double get_value(string message){
   double value;
   do{
       cout<<message;
       cin>>value;
       if(value<0){
           cout<<"Value cannot be less than zero.\n";
       }
   }while(value<0);
   return value;
}

// below are the two overloaded functions
// for in patients
double getCharges(double days, double daily_rate, double med_charges, double service_charges){
   // calculate total charges and return the total amount in one line
   return days*daily_rate + med_charges + service_charges;
}

// for out patients
double getCharges(double med_charges, double service_charges){
   return med_charges+service_charges;
}

// function prompts for valid patient type
// until user enter either I or O
void get_choice(char &letter){
   do{
       cout<<"Enter your choice (I for in-patient O for out-patient): ";
       cin>>letter;  
   }while(letter!='I' && letter!='O');
  
}

int main(){
  
   char patient_type;
   double days;   double rate,med_charges,service_charges;
   get_choice(patient_type);
  
   // when patient is in patient we ask for days and rate also
   if(patient_type=='I'){
       days = get_value("Enter the number of days spent in hospital: ");
       rate = get_value("Enter the daily rate: ");
   }
   // med and services charges are common for both types
   med_charges=get_value("Enter the hospital medication charges: ");
   service_charges=get_value("Enter the hospital service charges: ");
  
   double total_charges=0.0;
  
   // when in patient we call getCharges with 4 parameters
   if(patient_type=='I')
   {
       total_charges = getCharges(days,rate,med_charges,service_charges);
   }else{
       // if out paitent we call getCharges with only two parameters
       total_charges = getCharges(med_charges,service_charges);
   }
   // out put the total charges
   cout<<"Total Charges: $"<<total_charges<<endl;
  
}
