Create a Database

Write a C++ program to create a database of the following items of the derived class. 

Name of the patient, sex, age, ward number, bed number, nature of the illness, date of admission. 

Design a base class consisting of data members: name of the patient, sex and age; and another base class consisting of the data members: bed number and nature of the illness. The derived class consists of the data member, date of admission.

(i) Add a new entry.

(ii) List the complete record.

Program Code:

#include<iostream>

using namespace std;

// declaration of base class A with data members and member functions

class A

{

protected:

char name[20];

char sex[10];

int age;

void get_data()

{

cout<<"Enter the name :";

cin>>name;

cout<<endl;

cout<<"Enter the age :";

cin>>age;

cout<<endl;

cout<<"enter the sex :";

cin>>sex;

cout<<endl;

}

void disp_data()

{

cout<<"Name :";

cout<<name;

cout<<endl;

cout<<"Age :";

cout<<age;

cout<<endl;

cout<<"Sex:";

cout<<sex;

}

};

// declaration of second base class b with data members and member functions

class B

{

protected:

int bed_number;

char nature_illness[40];

public:

void get_data()

{

cout<<"Enter the bed_number:";

cin>>bed_number;

cout<<endl;

cout<<"Enter the nature_illness:";

cin>>nature_illness;

cout<<endl;

}

void disp_data()

{

cout<<"bed_number : ";

cout<<bed_number;

cout<<endl;

cout<<"nature_illness : ";

cout<<nature_illness;

cout<<endl;

}

};

// declaration of derived class C which is derived from two base class A and B

class C : public A, public B

{

int date_admission;

public:

void get_data()

{

A :: get_data();// function of base class A call

B :: get_data();// function of base class B call

cout<<"Enter Data of Admission : ";

cin>>date_admission;

}

void disp_data()

{

A :: disp_data();// function of base class A call

B :: disp_data();// function of base class B call

cout<<"Date of Admission : ";

cout<<date_admission;

}

};

// declaration of main function 

int main()

{

C c1; // object of class C declaration

cout<<"Adding a new record to database : ";

c1.get_data();// function of derived class C call

cout<<endl;

cout<<"Displaying the added record to database : ";

c1.disp_data();// function of derived class C call

cout<<endl;

return 0;

}
