Question

C++ language

Please help.

Create a small hospital system, where patients can book appointments. The program should be able to take a patient’s information and the appointment that they’d like to book. It should also be able to display the patients names in order of their appointments (ascendingly).

Your program should consist of:

Class Person: with private variables name, ID and age. A default and a copy constructor, setters and getters and a print function.

Class Patient: inherits from Person. Private variables: struct appointment : consisting of hours and mins. doctorID: to indicate the ID of the doctor assigned to their case. Overload the <,>,== operators to compare between patients’ appointments. Add any setters/getters necessary.

Class Doctor: inherits from Person. Private variables: counter: number of appointments the Doctor has for the day Array of struct (appointment): that indicates the times the Doctor is booked. A function that returns true if the Doctor is available at a certain time, false if not. Add any setters/getters necessary Template Class Queue A generic queue class to work with any data type. Main functions: Push, Pop.

Program Workflow : a) You could read multiple Doctor’s data from the user/from a file or initialize them within the main function.

b) Read multiple patients data from a file or from the user. Insert patients with their appointment into an array of patients.

c) The program should assign each patient to the doctors in the order the doctors are stored so the first patient would go to the first doctor, and the second patient to the second doctor and so on till you go back to the first doctor.

d) If a doctor is not available in the appointment the patient chose then the next doctor should be considered and so on. (Use the doctor class functions to check the doctor’s availability).

e) The patients should be inserted into a queue in order of their appointments. f) Print the information of the patients in order, along with the info of their assigned doctor.

CODE:

#include<bits/stdc++.h>
using namespace std;
struct appointment{
int hours, minutes;
};
class Person{ //Person class
private:
string name;
int id, age;
public:
Person(int id, string name, int age){ //default constructor
setName(name);
setAge(age);
setId(id);
}
Person(const Person &p){ //copy constructor
name = p.name;
id = p.id;
age = p.age;
}
void setName(string n){ //setters
name = n;
}
void setId(int i){
id = i;
}
void setAge(int a){
age = a;
}
string getName(){ //getters
return name;
}
int getId(){
return id;
}
int getAge(){
return age;
}
void print(){ //Print function
cout<<"Name: "<<name<<endl;
cout<<"ID: "<<id<<endl;
cout<<"Age: "<<age<<endl;
}
};

class Patient: public Person{ //inherited Patient class from Person
appointment app;
int doctorId;
public:
Patient(int id, string name, int age): Person(id, name, age){

}
void setDoctorId(int id){
doctorId = id;
}
void setAppointment(appointment ap){
app.hours = ap.hours;
app.minutes = ap.minutes;
}
int getDoctorId(){
return doctorId;
}
};

class Doctor: public Person{ //inherited Doctor class from Person
int counter=0;
appointment apps[100];
public:
Doctor(int id, string name, int age): Person(id, name, age){

}
bool isAvailable(){
if(counter<100)
return true;
else return false;
}
void setAppointments(appointment app){
apps[++counter].hours = app.hours+1;
apps[counter].minutes = app.minutes;
}
int getCounter(){
return counter;
}
appointment getAppointment(){
return apps[counter];
}
};
queue<Patient> Q; //generic queue

int main(){
Doctor d[] = {Doctor(100, "Shubham Acharya", 23), Doctor(200, "Ankit Singh", 35)}; //doctor initialistion
Patient p[] = {Patient(1, "Anjali Sahu", 24), Patient(2, "Shweta Sah", 22), Patient(3, "Roshan Gupta", 23)}; //Patient initialistion
for(int i=0;i<3;i++){ //Assign doctors in round robin fashion
if(d[i%2].isAvailable()){
p[i].setDoctorId(d[i%2].getId());
d[i%2].setAppointments(d[i%2].getAppointment());
p[i].setAppointment(d[i%2].getAppointment());
Q.push(p[i]);
}
while(!Q.empty()){ //pop queue and print info of patients
Patient p = Q.front();
Q.pop();
p.print();
cout<<"Assigned Doctor's Info: "<<endl; //print assigned doctor's info
for (person:d){
if(p.getDoctorId() == person.getId()){
person.print();
}
}
cout<<"========================================================"<<endl;
}
}
return 0;
}
