phone numbers using classes?

**correlcj** · 11-09-2002

Can anyone point me to a simple phone number program using classes that i can learn from? Any examples are welcome.

This is what i am trying to accomplish.

A phone number consists of four separate pieces of information: an area code, an exchange, a local number, and a long-distance indicator (true or false). Design and build a PhoneNumber class that models a phone number, providing operations to construct, input, output extract each of the data members of a PhoneNumber object, and indicate whether or not the number is long-distance. The input operation should read a local or long-distance number and set the long-distance indicator accordingly. The output operation should display a local number differently from the way it displays a long-distance number (e.g., 555-1234 vs. (616) 555-1234).

Thanks!!

Code:

#include <iostream>
#include <map>
#include <string>
int main()
{
  using namespace std;
  map<string,int> numbers;
  numbers["petter"] = 19339;
  numbers["sos"] = 112;
  //...

  string s;
  cout << "Whose number do you want?";
  cin >> s;
  cout << s << "\'s number is:" << numbers[s];
}

Thanks for the input but I need something like so

class PhoneNo

public:

//blah

private:

//blah

to this effect so i can learn from...

Can you help me?

p.s. here is some code i have tinkered with but still clueless...

Code:

class PhoneNumber
	{
public:


	// have a clue

private:
		int myLocalNumber;	//"555-5555"
		int myLongDistance;	//"813-555-5555"
		int myAreaCode;		//"813"
		int myLocalExchange;	//
	};

i am clueless on where to put the code, how to run it so it would work. I think i would place it in a file like so...PhoneNo.h. Yes or no?

Can someone shed some light for me?

Code:

class PhoneNumber
{
   public:
     //declare constructor here
     //declare functions to change and retrieve each of the private data members here
     //declare function to get input here
     //declare function to output phone number here
 
   private:
     //declare private data members here
     int areaCode;
     int exchange;
     int localNumber;
     bool longDistance;
};

//function definitions for each of the public member functions go here.

The input function may be quite variable depending how you obtain input: from a file, user input, a single string input, three int inputs and one boolean input, etc. Presumably the instructions provided by the instructor gave you how the input will be obtained.
