Question

Please write with structure, not class! Add comments for clear understanding. Write code without using scope resolution operators.

Write an ADT to represent a doctor's medical registration number (a non-negative integer), number of patients (a non-negative integer), and income (non-negative, in euros).

A doctor's information should be represented by a structure with 3 fields: medical_reg and num_patients of type int, and income of type float.

Your ADT should define four interface functions to carry out the following operations:

· Construct a new doctor, given input arguments for medical registration number, number of patients, and income. This function should not do any error-checking on its inputs.

· Print out to the screen the values of medical registration number, number of patients, and income for a specified doctor.

· Add two doctors to return a new ‘doctor' by adding the values of the corresponding number of patients and income fields, inserting a dummy value for the medical registration number of the new ‘doctor'. A dummy value is something that could not be a valid value; you must decide what an appropriate dummy value is in this case.

· Compare 2 doctors to determine which of them is "greater", according to these rules: the doctor with the higher income is greater; if the 2 doctors have the same income, the doctor with more patients is greater; if both income and number of patients are the same, the 2 doctors are equal. This function does not return a value, but prints out the values for the "greater" doctor or that the doctors are equal, as appropriate.

Write a main function which tests each aspect of your work:

ask the user for the values of medical registration number, number of patients, and income for 2 doctors;

print out each doctor's values;

then print out the values for the addition of these 2 doctors, and determine which of them (if either) is "greater".

You may assume that the user enters valid values for each doctor's fields from the keyboard.

So you should write three files:

· A header file to hold the structure definition and the prototypes of the interface functions

· A C++ source file to hold the implementations of the interface functions

· Another C++ source file to hold the main program

Answer:-

Hello, I have written the required program in CPP. Please find it below. I have included all the 3 required files code.

Doctor.h

struct Doctor
{
   int medical_reg;
   int num_patients;
   float income;  
};
Doctor constructDoctor(int, int, float);
void displayDoctorInfo(Doctor);
Doctor addDoctor(Doctor, Doctor);
void compareDoctor(Doctor,Doctor);

Doctor.cpp

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

Doctor constructDoctor(int m,int n, float i)
{
   Doctor d1 = {m,n,i};
   return d1;
}

void displayDoctorInfo(Doctor d)
{
   cout<<"Medical Registration Number is "<<d.medical_reg<<endl;
   cout<<"Number of Patients is "<<d.num_patients<<endl;
   cout<<"Income is "<<d.income<<endl;
}

Doctor addDoctor(Doctor d1, Doctor d2)
{
Doctor d3 ={-1, d1.num_patients+d2.num_patients,d1.income+d2.income};
   return d3;  
}

void compareDoctor(Doctor d1,Doctor d2)
{
   if(d1.income>d2.income)
   {
   displayDoctorInfo(d1);  
   }
   else if(d1.income<d2.income)
   {
   displayDoctorInfo(d2);  
   }
   else
   {
   if(d1.num_patients>d2.num_patients)
   {
   displayDoctorInfo(d1);  
   }
   else if(d1.num_patients<d2.num_patients)
   {
   displayDoctorInfo(d2);  
   }
   else
   {
       cout<<"Doctors are equal";
       }  
   }
}

Source.cpp

#include<iostream>
#include "Doctor.cpp"
using namespace std;

int main()
{
   int medical_reg,num_patients;
   float income;
   cout<<"Enter details for first Doctor\nEnter Medical Registration Number";
   cin>>medical_reg;
   cout<<"Enter the number of patients ";
   cin>>num_patients;
   cout<<"Enter Income";
   cin>>income;
   Doctor d1 = {medical_reg, num_patients, income};
   cout<<"Enter details for Second Doctor\nEnter Medical Registration Number";
   cin>>medical_reg;
   cout<<"Enter the number of patients ";
   cin>>num_patients;
   cout<<"Enter Income";
   cin>>income;
   Doctor d2 = {medical_reg, num_patients, income};
   cout<<"Information for First Doctor\n";
   displayDoctorInfo(d1);
   cout<<"Information for Second Doctor\n";
   displayDoctorInfo(d2);
   cout<<"Information for Third Doctors by adding these two Doctors\n";
   displayDoctorInfo(addDoctor(d1,d2));
   cout<<"Information for greater Doctor\n";
   compareDoctor(d1,d2);
}

Screenshot of Code:-

Please refer to the screenshot of the code for properly understanding the indentation of the code.

Doctor.h

Doctor.cpp

Source.cpp

OUTPUT:-

Note:- Here, in the addDoctor() function, I have used a dummy value for medical registration number of a doctor which is -1.

I hope it would help.

Thanks!
