Debug

May 26th, 2006

Hi there, could someone please help me debug this code. I need it to perform the following tasks
1. Ask the user for the number of cars he or she owns.
2. Create a class to represent a car, and then declare an array of cars.
3. Ask the user what the color, weight, and model is for each car he or she owns. Store this in the array.
4. Once the user has entered all data, calculate the combined weight of the cars.

>#include<stdafx.h>

What's that get rid of it?

>strcpy_s

What's that drop the subscript s.

>void main()

main should return an int, change to int main.

>new car fleet[number];

You don't need the new keyword

>fleet

This is not defined.

Is this better?
Can you please suggest a good C++ compiler. This code will not run on VC++ 8 thats is why I had all those additional things in my code.
Thanks

Hmm, have you tried dev++

I see what you were doing now with the new keyword. So you might need that.

To be honest there is so many ways you can write this. It all depends on the style your teacher is expecting from you.

For example you could do it like so:-
