Question

1. 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:
   1. The number of days spent in the hospital
   2. The daily rate
   3. Hospital Medication Charges
   4. Charges for hospital services (labs, tests, etc.)

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

1. Charges for hospital services (labs, tests, etc.)
2. Hospital Medication Charges

The program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for out-patient information. Both functions should return the total charges.

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

C++

Answer 1

Program:

#include <iostream>

using namespace std;

//Overloaded function declaration
float calculateCharge(int day, float r, float charge, float serviceCharge);
float calculateCharge(float charge, float serviceCharge);

int main()
{
//variables to hold type of patient, days, rate, and charges
char type;
int days;
float rate;
float charges,serviceCharges;
  
//User input for type of patient
cout<<"Admitted as in-patient or out-patient, i/o: ";
cin>>type;
if(type=='i')
{
//Loop till user enter any of negative value
do{
cout<<"The number of days spent in the hospital: ";
cin>>days;
cout<<"The daily rate: ";
cin>>rate;
cout<<"Hospital Medication Charges: ";
cin>>charges;
cout<<"Charges for hospital services (labs, tests, etc.): ";
cin>>serviceCharges;
if(days<0 || rate<0 || charges<0 || serviceCharges<0)
{
cout<<endl<<"None of the value can be negative";
}
}while(days<0 || rate<0 || charges<0 || serviceCharges<0);
  
//call function to calculate totalcharge and print
float totalCharge = calculateCharge(days,rate,charges,serviceCharges);
cout<<endl<<"Total charge: "<<totalCharge;
}
else if(type=='o')
{
//Loop till user enter any of negative value
do
{
cout<<"Hospital Medication Charges: ";
cin>>charges;
cout<<"Charges for hospital services (labs, tests, etc.): ";
cin>>serviceCharges;
if(charges<0 || serviceCharges<0)
{
cout<<endl<<"None of the value can be negative";
cout<<"Re-enter the value";
}
}while(charges<0 || serviceCharges<0);
//call function to calculate total charge and print
float totalMedical = calculateCharge(charges,serviceCharges);
cout<<endl<<"Total charge: "<<totalMedical;
}
else
{
cout<<"Invalid choice";
}
return 0;
}

//function definition to calculate total charge
float calculateCharge(int day, float r, float charge, float serviceCharge)
{
return (day*r) + charge + serviceCharge;
}
float calculateCharge(float charge, float serviceCharge)
{
return charge+serviceCharge;
}

Output:
