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!

Operator ovleroading errors

Asked by Falmarri in Microsoft Visual C++.Net, C++ Programming Language

Tags: C++, operator, overloading, operator overloading

So I'm learning about operator overloading in class, and I totally get the concept, but I'm having syntax issues and such. Here are the methods that aren't compiling. First, I was under the impression you should have 2 different operator[] overloads for assignment and read only. It's says however

/home/falmarri/Dropbox/Programs/hw06-knapp-david/src/polyclass.h:34: error: int& PolyClass::operator[](int) cannot be overloaded

/home/falmarri/Dropbox/Programs/hw06-knapp-david/src/polyclass.h:32: error: with const int PolyClass::operator[](int)

And then I get several of these:

/home/falmarri/Dropbox/Programs/hw06-knapp-david/src/polyclass.cpp:147: error: std::ostream& PolyClass::operator<<(std::ostream&, const PolyClass&) must take exactly one argument

I was told that errors like that suggest that I've forgotten to make that method a friend function. But I've included it as a friend like I know how. It may not be correct.

/home/falmarri/Dropbox/Programs/hw06-knapp-david/src/polyclass.cpp:100: error: PolyClass PolyClass::operator+(const PolyClass&, const PolyClass&) must take either zero or one argument

I can post more information if needed, I'd prefer not to post all my source though. I'm assuming it's just fundamental misunderstanding of how this works.

             32	const int operator[] ( const int lhs);
	
34	int& operator[] (const int lhs);
 
	friend std::ostream &operator<<(std::ostream &out, const PolyClass& rhs);
