C++ Programming: So I received help with a code that takes a diabetics name, age, food consumed, and the blood sugar (before and after) using linked lists and then copies the information to a file. How would I make this so that the Person class only holds name and age, but then an inherited class Diabetic takes the reigns and has name+age from Person and then adds the food, and blood sugar results? Is that even possible with linked lists? And how would I create an option on whether user would like to copy to a file instead of automatically copying it? code: Program code: #include #include #include using namespace std; struct Record { string name; int age; string food; int after; int before; Record *next; }*head; class People { public: int count=0; Record* create_node(string,int,string,int,int); void insert(); void display(); People() { head = NULL; } }; int main() { cout << \"patient details\" << endl << endl; head = NULL; People p; p.insert(); p.insert(); p.display(); return 0; } Record *People::create_node(string nam,int a,string foo,int af,int bef) { struct Record *newRecord, *s; newRecord = new Record; if (newRecord == NULL) { cout<<\"Memory not allocated \"< name = nam; newRecord -> age = a; newRecord -> food = foo; newRecord -> after = af; newRecord -> before = bef; newRecord -> next = NULL; return newRecord; } } void People::insert() { string s_name; int s_age; string s_food; int s_after; int s_before; Record *Record_ptr,*newRecord; ofstream outfile; outfile.open(\"Patient.txt\"); cout<<\"Enter patient details\"; cin>>s_name>>s_age>>s_food>>s_after>>s_before; outfile<next = NULL; } else { Record_ptr = head; while(Record_ptr -> next) Record_ptr = Record_ptr -> next; Record_ptr -> next = newRecord; } outfile.close(); } void People::display() { Record *Display_ptr; Display_ptr = head; while(Display_ptr != NULL) { cout << Display_ptr -> name << endl; cout << Display_ptr -> age << endl; cout << Display_ptr -> food << endl; cout << Display_ptr -> after << endl; cout << Display_ptr -> before << endl; Display_ptr = Display_ptr -> next; cout << endl; } cout<<\"\ Number of patient in file:\"< Solution #include #include #include #include #include #include class patient { public: char name[20]; char blood_group[5]; int pat_id; long int phn; int a; void patientdata(); void showdata(); }; void patient::patientdata() { cout<<\" ***************************************************************************** **\ \"; cout<<\" \ \ \\t\\t\\tCreate New Patient Database \"; cout<<\" ***************************************************************************** **\ \"; cout<<\"\ Enter Patient ID : \"; cin>>pat_id; cout<<\"\ Enter Patient Name : \"; cin>>name; cout<<\"\ Enter Patient Blood Group : \"; cin>>blood_group; fflush(stdin); cout<<\"\ Enter Patient Phone : \"; cin>>phn; } void patient::showdata() { cout<<\"\ Patient ID\\t: \"<>a; char x; switch (a) { case 1: clrscr(); fstream f; f.open(\"patient\",ios::in|ios::out|ios::ate|ios::app|ios::binary); char an.

So I received help with a code that takes a diabetics name, age, food consumed, and the blood
sugar (before and after) using linked lists and then copies the information to a file. How would I
make this so that the Person class only holds name and age, but then an inherited class Diabetic
takes the reigns and has name+age from Person and then adds the food, and blood sugar results?
Is that even possible with linked lists? And how would I create an option on whether user would
like to copy to a file instead of automatically copying it?
