Question

Write the following c++ program.

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 out-patient. Data entered for in-patient: The number of days spent in the hospital The daily rate Hospital medication charges Charges for hospital services (lab tests, etc.) Data entered for out-patients: Hospital medication charges Charges for hospital services (lab tests, etc.) The program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other function accepts arguments for the out-patient information. Both functions should return the total charges. The main function prints the total charges. The program will continue to process patient data for as long as the user indicates his/her intent to continue. Input Validation: Do not accept negative numbers for any data. Please pay attention to the input validation.

Explanation / Answer

#include<iostream>

using namespace std;

//function to calculate total charge for in-patient
double calculateCharge(int days, double dailyRate, double medicationCharge, double serviceCharge){
   double totalCharge = 0;
   totalCharge = (days*dailyRate) + medicationCharge + serviceCharge;
   return totalCharge;
   }
  
//function to calculate total charge for out-patient
double calculateCharge(double medicationCharge, double serviceCharge){
   double totalCharge = 0;
   totalCharge = medicationCharge + serviceCharge;
   return totalCharge;
   }
