uh-oh - - need help, lots of help me thinks
ever had that feeling that you have just finished fixing your code and you are about to try and compile it for the last time, and then you see the words "There are errors" and you start to wonder where you can get some prozac from, well i call that saturday, 30 June 2001
If i said that knew exactly how this program works i'd be a liar. im sure i have the genetic disorder that curses me to be a c++ newbie for eternity :(
here are my errors

ASKER CERTIFIED SOLUTION
membership
This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
next you have a constructor defined for the order class like
Order::Order(int ID_Num_Passed_Thru, char Reg_Num_Passed_Thru, char Brand_Passed_Thru, char
Car_Model_Passed_Thru,
char Car_Sub_Model_Passed_Thru,
Car_Milage_Passed_Thru,
float Car_Price_Passed_Thru);
however this constructor is not declared in the class definition. You have to declare it in the class.
The code for this constructor performs
strcpy(Reg_Num,Reg_Num_Pas
strcpy(Car_Brand,Car_Brand
strcpy(Car_Model,Car_Model
strcpy(Car_Sub_Model,Car_S
strcpy(Car_Colour,Car_Colo
strcpy(Car_Age,Car_Age_Pas
strcpy(Car_Milage,Car_Mila
strcpy(Car_Price,Car_Price
as if all those variables are strings. But they are not.All of the XXXXX_passed_thru varaibles are single characters, not arrays of characters. i.e they are not strings, they are just one character. Furthermore Car_price is not even supposed to be a string. it is supposed to be a number, a float.

Then in the Order constructor that takes an order object as a parameter (via a pointer) you have
strcpy(Car_Price,Odr->Car_
again Car_price is not a string.
Then in
void Order::View_Car()
{ char output[70];
cout <<"ID Number - "<<ID_Num_Passed_Thru <<"\n";
cout <<"Registration Number - "<<Reg_Num_Passed_Thru <<"\n";
cout <<"Car Brand - "<<Car_Brand_Passed_Thru <<"\n";
cout <<"Car Model - "<<Car_Model_Passed_Thru <<"\n";
cout <<"Car Sub Model - "<<Car_Sub_Model_Passed_Th
cout <<"Car Colour - "<<Car_Colour_Passed_Thru <<"\n";
cout <<"Car Age - "<<Car_Age_Passed_Thru <<"\n";
cout <<"Car Price - "<<Car_Price_Passed_Thru <<"\n";
}
You have defined "output" but never use it. You code is printing all these XXXXX_passed_thru variables, but they are not defined. The names of the class's data mebers don't end in "passed_thru".
in
void Order::Save_Inv(){
you do the same thing. All the vairalbe names end in pass_thru.
That shoudl be enough for the time being. Fix those things and look for other stuff liek that. Just plain try to clean stuff up. This code is VERY far from being compileable. That makes your task extremely hard. You should always make changes in small increments and compile after each change and fix the problems before goign on to the next change. In keeping with that it would probably be a good idea to commment ouut nearly everything and get the code to compile. Then slowly add back peices (uncomment them) and get them to compile. For examle, leave the list stuff commented out and start uncommenting the order cloass, but uncomment it one function at a time and get those functions to work before uncommenting the next.
This allows you to home in on where the errors occur.
strcpy(Car_Price,Odr->Car_
again Car_price is not a string.
Then in
void Order::View_Car()
{ char output[70];

cout <<"Registration Number - "<<Reg_Num_Passed_Thru <<"\n";
cout <<"Car Brand - "<<Car_Brand_Passed_Thru <<"\n";

Homework Eh !
Sorry, can't debug your entire program.
I know however how such a great number of errors
can psyche you out. You have to debug you own program.
This is what I would recommend.
1) Take the errors one at at time, don't let all those
errors get to you.
2) Check spelling ( ex. Milage mileage )
3) Check data types, ( ex. int, char ) Make sure
you are not trying to convert one into the other.
4) Don't make a function if your not going to
use it.
Many of the errors are repeated errors.
Don't design a program in full, then try to debug.
As you make a program, test the individual functions for errors, catching them along the way will stop you from
repeating them as the program developes.
Be very methodical in your design.
C++ can be very hard to learn if your just starting out.
The rewards in the end are well worth the struggle.

ASKER
i see i have a rather large task ahead of me,
thanks for pointing out the error of my ways m8
thanks for pointing out the error of my ways m8
Post your code when you get more done....
so for example,
In the Order class you call a float "car_price" Later on in Add_A_Car() you use the same name for an array of ints. then in Add_a_Car() you try to treat the array of ints car_price as if it is an array of characters by doing a gets(), then in Change_Car_details_By_reg you declare it as an array of character and treat it as such. But then you pass it to the order() constructor that doesn't take an array of character. its a mess.
Its hard to image how to fix it because its hard to know what you even intend to do.
But you need to give things very clear names that make clear what the purpose of the data is and what type of data it is. "car price" sounds like a single number, like a float. it doesn't sound like a string. it doesn't sound like an array of numbers. That might be "car prices", but not "car price"
