Question

My assignment is listed below. I already have the code complete, but I cannot figure out how to complete this portion:
You must create a makefile to compile and build your program.

I can't figure out if I need to create a makefile, and if I do, what commands do I use for that?

Create a  ContactInfo class that contains the following member variables:

• name
• age
• phoneNumber

The ContactInfo class should have a default constructor that sets name = "", phoneNumber = "", and age = 0.

The ContactInfo class should have a constructor that accepts the name and phone number as parameters and sets name = <value of parameter name>, aAge = 0, and phoneNumber = <value of parameter phone number>.

The ContactInfo class should have accessor and mutator functions for each member variable.

The ContactInfo class should have a function called canVote that returns a boolean. It will return true if age is >= 18. Otherwise, it will return false.

Create three instances of this class in the main function

Write a C++ function (outside of the class) that will display (as shown below in the sample run) an instance of the ContactInfo class. Call the function to display the three instances you created in the main function.

Make sure your program conforms to the following requirements:
1. This program should be called ContactInfoApp.cpp. The header file should be called ContactInfo.h and place member function definitions in ContactInfo.cpp. You must submit these three files.

Include the basic header in your program. (5 points deduction if missing)

2. Properly set up the ContactInfo class and declare three instances of ContactInfo (45 points)

3. Write a C++ program that will create and display (as shown below in the sample run) three instances of the ContactInfo class. (25 points).

4. Add comments wherever necessary. (5 points)

5. You must create a makefile to compile and build your program. In addition, you must test your program on linprog.cs.fsu.edu. (25 points)

(For this step - you must include a copy of the makefile and a copy of the terminal output from a compile and test run as shown below.)

Answer 1

ContactInfo.h:

Code as text (to copy):

#ifndef _CONTACT_INFO_H_

#define _CONTACT_INFO_H_

#include <iostream>

#include <string>

using namespace std;

class ContactInfo {

private:

string name;

string phoneNumber;

int age;

public:

// default constructor

ContactInfo();

// parameterised constructor

ContactInfo(string _name, string _phoneNumber);

// accessor

string getName();

string getPhoneNumber();

int getAge();

// mutators

void setName(string _name);

void setPhoneNumber(string _phoneNumber);

void setAge(int _age);

// member functions

bool canVote();

};

#endif

ContactInfo.cpp:

Code as text (to copy):

#include "ContactInfo.h"

// Default constructor

ContactInfo::ContactInfo() {

name = "";

phoneNumber = "";

age = 0;

}

// Parameterised constructor

ContactInfo::ContactInfo(string _name, string _phoneNumber) {

name = _name;

phoneNumber = _phoneNumber;

age = 0;

}

// Accessor functions

// function to get name of contact

string ContactInfo::getName() {

return name;

}

// function to get phone number of contact

string ContactInfo::getPhoneNumber() {

return phoneNumber;

}

// function to get age of contact

int ContactInfo::getAge() {

return age;

}

// Mutator functions

// function to set name of contact

void ContactInfo::setName(string _name) {

name = _name;

}

// function to set phone number of contact

void ContactInfo::setPhoneNumber(string _phoneNumber) {

phoneNumber = _phoneNumber;

}

// function to set age of contact

void ContactInfo::setAge(int _age) {

age = _age;

}

// Member functions

// boolean function

// returns true if age >= 18 otherwise return false

bool ContactInfo::canVote() {

return age >= 18;

}

ContactInfoApp.cpp:

Code as text (to copy):

#include <iostream>

#include <string>

#include "ContactInfo.h"

using namespace std;

// function to display an instance of the class ContactInfo

void displayContactInfo(ContactInfo& obj) {

cout << "Name: " << obj.getName() << endl;

cout << "Phone Number: " << obj.getPhoneNumber() << endl;

cout << "Age: " << obj.getAge() << endl;

cout << "Can vote?: ";

if (obj.canVote()) cout << "Yes" << endl;

else cout << "No" << endl;

}

int main() {

// Create three instances of class ContactInfo

ContactInfo instance1("Kristen Lee", "555-2021");

instance1.setAge(45);

ContactInfo instance2, instance3;

instance2.setName("Joe Smith");

instance2.setPhoneNumber("111-9999");

instance2.setAge(5);

instance3.setName("Tom Hanks");

instance3.setPhoneNumber("111-8888");

instance3.setAge(75);

// call function to display details of three instances

displayContactInfo(instance1); cout << endl;

displayContactInfo(instance2); cout << endl;

displayContactInfo(instance3);

return 0;

}

makefile:

makefile as text (to copy):

CXX = g++

CXXFLAGS = -Wall

ContactInfoApp: ContactInfoApp.o ContactInfo.o

$(CXX) $(CXXFLAGS) -o ContactInfoApp ContactInfoApp.o ContactInfo.o

ContactInfoApp.o: ContactInfoApp.cpp

$(CXX) $(CXXFLAGS) -c ContactInfoApp.cpp

ContactInfo.o: ContactInfo.cpp ContactInfo.h

$(CXX) $(CXXFLAGS) -c ContactInfo.cpp
