Question

Define a member function PrintAll() for class PetData that prints output as follows. Hint: Make use of the base class' PrintAll() function.
Name: Fluffy, Age: 5, ID: 4444
Given this code:

#include
#include
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;
};

private:
int ageYears;
string fullName;
};

class PetData: public AnimalData {
public:
void SetID(int petID) {
idNum = petID;
};

// FIXME: Add PrintAll() member function

/* Your solution goes here */

private:
int idNum;
};

int main() {
PetData userPet;

userPet.SetName("Fluffy");
userPet.SetAge (5);
userPet.SetID (4444);
userPet.PrintAll();
cout << endl;

return 0;
}

Answer:

Following are the program in the C++ Programming Language.

//set header file

#include <iostream>

//set header file for string

#include <string>

//set namespace

using namespace std;

//define class

class AnimalData

{

//set access modifier

public:

//define function

void SetName(string givenName)

{

//initialize the value of function's argument

fullName = givenName;

};

//define function

void SetAge(int numYears)

{

//initialize the value of function's argument

ageYears = numYears;

};  

//here is the solution

//define function

void PrintAll()

{

//print output with message

cout << "Name: " << fullName<<endl;

//print output with message

cout << "Age: " << ageYears<<endl;

};

//set access modifier

private:

//set integer data type variable

int ageYears;

//set string data type variable

string fullName;

};

//define class and inherit the parent class

class PetData: public AnimalData

{

//set access modifier

public:

//define function

void SetID(int petID)

{

idNum = petID;

};

//override the function for print id

void PrintAll()

{

AnimalData::PrintAll();

cout << "ID: " <<idNum ;

};

//set access modifier

private:

//set integer type variables

int idNum,fullName,ageYears;

};

//define main method

int main()

{

//create object of the child class

PetData userPet;

//call function through object

userPet.SetName("Fluffy");

//call function through object

userPet.SetAge (5);

//call function through object

userPet.SetID (4444);

//call function through object

userPet.PrintAll();

cout << endl;

return 0;

}

Output:

Name: Fluffy

Age: 5

ID: 4444

Explanation:

Following are the description of the program:

• Set required header file and namespace.
• Define class 'AnimalData' and inside the class, set integer data type variable 'ageYears', string data type variable 'fullName'.

1. Then, define function 'SetName()' with string data type argument 'givenName' and initialize the value of argument in the string variable.
2. Then, define function 'SetAge()' with integer data type argument 'numYears' and initialize the value of the argument in the integer variable.
3. Define function 'PrintAll()' to print the value of the following variables with message.

• Define class 'PetData' and inherit the parent class in it, then set integer data type variable 'idNum'.

1. Then, define function 'SetID()' with integer data type argument 'petID' and initialize the value of the argument in the integer variable.
2. Override the function 'PrintAll()' to print the value of the following variable with message.

Finally, define main method and create the object of the child class, then call the following functions through the class object.
