Question

You are to create a class called Person. You should create the definition of the class Person in a file person.h and the functions for Person in person.cpp. You will also create a main program to be housed in personmain.cpp.

A Person will have attributes of

• Height (in inches)
• Weight (in pounds to 2 decimal places)
• Name (string)
• Gender (‘m’ or ‘f’)
• Ethnicity/Race (could be more than one word)
• Occupation (also more than a single word)

A Person will have the following methods

• Accessors for all attributes
• Mutators for all attributes
• A default constructor that sets all data elements to 0 or blank text as appropriate
• A fully specified constructor that allows defining values for all attributes
• A printinfo method that will display all the info for a person in a logical and well formatted way including labels for each of the attribute fields

personmain.cpp should perform the following actions

• Dynamically allocate an array of 4 Persons
• Prompt the user for information about each of the four persons and store that information in one of the array elements
• Print the information for each Person
• Clean up all allocated space

// person.h
#ifndef PERSON_H
#define PERSON_H

#include <iostream>
#include <string>

using namespace std;

class Person

private:
string name;
int height;
double weight;
char gender;

public:

Person(string name, int height, double weight, char gender, string race, string occupation);
void setName(string name);
void setHeight(int height);
void setWeight(double weight);
void setGender(char gender);
void setRace(string race);
void setOccupation(string occupation);
string getName();
int getHeight();
double getWeight();
char getGender();
string getRace();
string getOccupation();
void printInfo();

// display the details of persons
cout<<"Details of all persons:"<<endl;

// delete the memory allocated
delete[] persons;

return 0;

// end of personmain.cpp
