Answer to Question #284249 in C++ for Mehtab

Question

Implement a class Address. An address has

 a house number,

 a street,

 a city,

 a state and

 a postal code.

Supply two constructors:

 the default no-argument constructor that initializes different members

 one with complete address.

 Supply a print function that prints the address with the street on one line and the city,

state, and postal code on the next line.

 Supply a method verifyAddress that tests whether an address is valid (and does not

contain default values)

 Supply a method compareTo that tests whether one address comes before another when

the addresses are compared by postal code

Write a small program to test your class.

Answer 1

#include<conio.h>
#include <iostream>
# include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include <cmath>
#include<dos.h>

using namespace std;
