The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

global typedef

Asked by nozzle99 in C++ Programming Language

Tags: global

I try to make a linked list class for my school project and got some problem with typedef thing.


MY HEADER FILE LOOKS LIKE (list.h):

struct node;
struct dataTypeList;
typedef dataTypeList itemListType;

class list
{
  public:
    list();
    ~list();
    void getItem(itemListType &newItem);

...
};


MY CPP FOR THE HEADER FILE (list.cc):

include "list.h"

struct node
{
   ...
};

struct dataTypeList
{
   int value;
   int multiple;
};

...


MY PROGRAM FILE (try.cc):

include "list.h"

struct dataTypeList
{
   int value;
   int multiple;
};
...

the problem is: do I have to put the struct statement in both class (my program class and class implementation for my header file). I need to make 2 different programs which will use that linked list container, the first program will use that struct while the data for the other only an integer. If I put the struct in the list.cc, my second program will be nasty because I have to use that struct while I don;t need it.

is there any way I can make the itemListType in list.h to be default to int (ie. typedef int itemListType). And if I declare the typedef in try.cc (ie. typedef dataListType itemListType), the itemListType in list.h and list.cc will be dataListType (but I don't want to declare the struct in the list.cc)?

BTW, I'm using CC compiler for unix.
