Please Help!! This is an C++ problem. Needs to be done with words and explain why.

Class Details

Sample Driver

Mailbox
Mailbox();
Mailbox( string address );

void setSize( int amount );
int getSize( );
void setAddress( string address );
string getAddress();
int getContents();

void pickupMail();
int deliverMail( int pieces );
string my_Address;
int my_Size;
int my_Contents;
#include <iostream>
#include "Mailbox.h"

using namespace std;

int main() {


// Let's use the Mailbox
cout << "Welcome to Howie's Post Service!" << endl;

Mailbox m;
m.setAddress( "1900 Pico Boulevard" );
m.setSize( 12 );
int postage = m.deliverMail( 10 );
m.pickupMail( );

return( 0 );

}

Sally The Programmer is working to improve the Mailbox class we have been working with in this course. She decides to make a parameterless constructor so that driver code can conveniently say:

Mailbox m;

and have everything still compile and work properly. In her implementation of the parameterless constructor, she writes:

Mailbox::Mailbox() {
// empty...
}

What is wrong with her approach and what would you recommend she do to avoid potential problems?
