[Inheritance Hierarchy] User Input on program with constructors. How ?

chandreu · 04-24-2008, 03:30 PM

Hie there everyone, i'm currently working on my assignment on Inheritance Hierarchy. I managed to construct everything, the program is fully working without any problem.

BUT now i need to make a user input based program instead of test program like what i've done. Its like, the user can input the receiver and sender name and informations. I thought this would be the easiest part but damn.. i'm trying everything i know trying to link the >>cin to the constructors above but none are working. Everything giving me error. Again and again.. errors.. errors.. errors..

Please help me. Any idea how to do it ? An example on how to create a user input for atleast the sender's name in this program would be very very much appreciated. The rest i can do it myself.

Thanks.

Code:

#include <iostream>
#include <iomanip>
#include <string>


using namespace std;

Er... I didn't see a 'std::cin' anywhere. What are you trying?

And also, can you edit your post and break the long lines? Your making my laptop cry.

I'm thinking that your package class could do with having the "where to send" and "where from" split out into a separate "address" class. You would then have two instances of that, sender and recipient in the package class, rather than repeating a bunch of member variables with sender and recipient prefixes. A further consequence of this would be that you could write a funciton to display an address, making your overall code a lot simpler.

You may even find that you can deal with address data completely independently from the package class, and just pass in a sender and receiver address into the constructor, taking the number of arguments to the constructor down to something manageable.

You have created perfectly named member functions. There's no need to adorn them with superfluous comments. I'd lose the comments at the end of every function, too.

Code:

// return sender's ZIP code
int Package::getSenderZIP() const
{
       return senderZIP;
} // end function getSenderZIP

Thanks for the replies. I edited my code as requested.

Sorry for the long lines, i didn't break the lines before bcoz it makes the code looks messy.

You wont find the 'std::cin' anywhere coz i'm using the namespace std therefore i don't need to declare the "std::cin" seperately.

What i'm trying to ask here:

Now you can see the constructor for each function TwoDayPackage and overNightPackage it goes on like

OvernightPackage (const string &sName, const string &sAddress, const string &sCity, const string &sState, int sZIP.......)

So, when i build my test program in int main() below, i simply create an object under that function and enter values that follow the same arrangement i made above (name, address, city, state, zip code.....)

Now, what im trying to ask is, how to make user input the values into the function instead of declaring it in the program itself. For example,

cout>> "please enter sender name : ";
cin>>sName; <----- sName refering to sender name in the OverNightPackage

Ofcoz it doesn't work simply this way as i'll definately will get "sName undeclared" (i'm just trying to give you a good picture about what i want my program to do). But there must be some way to achieve this thru other method. And all i'm asking for is this unknown method, how to do it ?

i removed most of the comments, hope its much easier for the eyes now. It is for my stupid lecturer anyway, he wanted it that way.

Mats, it took me almost 20 minutes to figure out what you are trying to say. Your explaination is crystal clear but its just that i'm quite new to this programming stuff. I understand now what you are saying thou but it gonna take me alot lot more time and i think thats what most probably i gotta do since there are no other better solution around.

I have 3 days remaining to complete this assignment.. plus another subject assignment.. gotta model a warrior character in 3ds max.. 4 days to deadline and i'm still figuring out what texture would fit on his butt... ;(

You can create extra variables to read the values into.

Code:

string sName;
cin >> sName;
OvernightPackage(sName, ...);

CornedBee... what you mean by extra variable ? I don't quite get it. Would you mind explaining me about it ?

matsp · 04-25-2008, 05:49 AM

Code:

string sName;
cin >> sName;

In the above piece of code, we would be reading in the sender name.

Hey guys... its finally working the way i want it. Great thanks to Mats and CornedBee. When i read CornedBee, i didn't get what he meant TILL only after reading Mats short reply, it "clickED" at the back of my head !!! Tried it and works like wonders !!!!

Thanks CornedBee !!!!
Thanks Mats !!!

This is the full user input code i did based on CornedBee's simple example.

Code:

void ChoiceOvernight()

string sName, sAddress, sCity, sState;
int sZIP;

string rName, rAddress, rCity, rState;

double w, cost, fee;

       {
         exit(0);
         }
         }
         }

I removed some part of my original code from the first post, worried if some of my lazier classmates googled, came across this code and submit it as their own. Hope its not against this forum rules or anything.

Thanks to you guys, now i can go back to my 3Ds Max and start editing my warrior's butt...
