The document provides code for defining a derived class 'petdata' that overrides the 'printall()' function of a base class 'animaldata'. The 'printall()' function in 'petdata' should display the name, age, and ID of a pet. It also indicates confusion regarding errors encountered while implementing this function.

1. C++
5.6.2 Basic derived class member override
Define a member function PrintAll() for class PetData that prints output as follows with inputs
"Fluffy, 5, andd 4444. Hint: Make use of the base class' PrintAll() function.
Name: Fluffy, Age: 5, ID: 4444
#include <iostream>
#include <string>
using namespace std;
class AnimalData {
public:
void SetName(string givenName) {
fullName = givenName;
};
void SetAge(int numYears) {
ageYears = numYears;
};
//Other parts omitted
void PrintAll() {
cout << "Name: " << fullName;
cout << "Age: " << ageYears;
};
class PetData: public AnimalData {
public:
void SetID(int petID) {

2. idNum = petID;
};
// FIXME: Add PrintAll() member function
void PrintAll() {
cout << "Name: " << fullName;
cout << ", Age: " << ageYears;
}
void PrintAll() {
AnimalData::PrintAll();
cout << ", ID: " << idNum << endl;
};
private:
int idNum;
};
I am confused with the printAll() section and it is printing errors
