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!

Difference between "void main()" and "int _tmain(int argc, _TCHAR* argv[])"?

Asked by broocrypt in Microsoft Visual C++, C / C++ / C# Editors and IDEs

Tags: , , ,

Hello. I am learning C++ and I am following a series of educational videos + some books. All these
books declare the main function as

void main()

However, when I downloaded and installed VC++ Express 2008 the default main declaration is

int _tmain(int argc, _TCHAR* argv[])

The programs run fine as well, but I really don't understand what's the difference, and it really bugs me the fact that I am using something I don't really understand. Adding to the confusion there's the fact that the videos I am
using use Microsoft Visual C++ as well (although I can tell it is not the 2008 version, probably an older one.)

So, basically what I would really know is:

1. The difference between the two declarations
2. Which one of the two should I consider "standard"
3. If there's really no standard to speak of,  but it is something strictly linked to my actual development environment, which in this case is VC++ 2008 Express.

Thank you. :)
