Question

Please answer the following in commented C++ code.

The purpose of this problem is to practice working with pointers and dynamic memory allocation. Consider the class Patient with the following private attributes long patientID; string name char gender; string birthDate You need to write a program that a) b) c) Declares an array of 4 pointers to objects of class Patient. Makes the array point to 4 new Patient objects. Sets the attributes of these objects to the following: 10023 Joe Garcia M 11/10/1979 10024 Suzy Walter F 01/01/2010 10025 Amelia Perez F 12/05/1983 10026 Tim Ducrest M 01/12/2000 d) Displays the data of each Patient in a neat table format. For example, ID Name Birth date Gender 10023 10024 10025 10026 Joe Garcia Suzy Walter Amelia Perez Tim Ducrest 11/10/1979 01/01/2010 12/05/1983 01/12/2000

Answer 1

code:

#include<iostream>

#include<cstdio>

using namespace std;

class Patient{

private:

long patientID;

string name;

char gender;

string birthDate;

public:

Patient(long id, string name, char gender, string date){

this->patientID = id;

this->name = name;

this->gender = gender;

this->birthDate = date;

}

void printdata(){

printf("%-10ld %-20s %-13s %-5c\n",patientID,name.c_str(), birthDate.c_str(), gender);

}

};

int main(){

Patient *p1 = new Patient(10023,"Joe Garcia", 'M', "11/10/1979");

Patient *p2 = new Patient(10024, "Suzy Walter", 'F', "01/01/2010");

Patient *p3 = new Patient(10025, "Amelia Perez", 'F', "12/05/1983");

Patient *p4 = new Patient(10026, "Tim Ducrest", 'M', "01/12/2000");

Patient *patient[4] = {p1,p2,p3,p4};

printf("%-10s %-20s %-13s %-9s\n", "ID", "Name", "Birth Date", "Gender");

for(int i=0;i<50;i++)

cout<<"-";

cout<<"\n";

p1->printdata();

p2->printdata();

p3->printdata();

p4->printdata();

return 0;

}

output:

ID Name Birth Date Gender 10023 10024 10025 10026 Joe Garcia Suzy Walter Amelia Perez Tim Ducrest 11/10/1979M 01/01/2010 12/05/1983 F 01/12/2000M
