// Person.cpp

#include "Person.h"

Person::Person( string first, string last, int years )
{
setFirstName(first);

} // end Person constructor

void Person::setFirstName( string first )
{

} // end function setFirstName

string Person::getFirstName()

{
lastName = last;
} // end function setLastName

string Person::getLastName()
{
return lastName;

#include <iostream>
using namespace std;

#include "Person.h"

int main()
{
Person person("John", "Smith", 19);


cout << "Created " <<person.getFirstName() << " " << person.getLastName() << ", age "
<<person.getAge() << endl;

person.getAge() = person.getAge() + 1;
cout << "Happy Birthday to " << person.getFirstName() << " "
<< person.getLastName() << endl;
} // end main


i get these error("1value required as left operand of assignment") when ever i build this program

use setAge() to set the age:

person.getAge() = person.getAge() + 1; -> person.setAge(person.getAge() + 1);
