Question

The following code:

#include <string>

using namespace std;

class personType
{
public:

void print() const;
void setName (string first, string last);
string getFirstName() const;
string getLastName() const;
personType(string first = "", string last = "");

Private:

string firstName;
string lastName;
};

void personType::print() const
{
cout<<firstName<<" "<<lastNname;
}

void persontype::setName(string first, string last)
{
firstName = first;
lastName = last;
}

string personType::getFirstName() const
{
return firstName;
}

string personType::getLastName() const
{
return lastName;
}

personType:personType(string first, string last)
{
firstName = first;
lastName = last;
} //end

defined a "class" personType to store the name of a perso. The member functions that we included merely print the name and set the name of a person. Redefine the class personType so that, in addition to what the existing "class" does, you can:

a) set the first name only
b) set the last name only
c) store and set the middle name
d) check whether a given first name is the same as the first name of this person
e) check whether a given last name is the same last name of this person. Write definitions of the member functions to implement the operations for this class. Also, write a program to test various operations on this "class".

I have written my own code and tryed to use the given code posted on this website ( "C++ programming 4th editon" by D.S. Malik. Chapter 12, Question 4). I keep getting LNK2019 Errors using VisualStudio 2008. Any help would be greatly appreciated.
