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!

Convert wchar_t* to char* function, memory cleanup problem

Asked by LearningCpp in Windows MFC Programming

Tags: c++

Hi,
in my application, at lot of places i need to convert a cstring or wchar_t* to char*, hence i wrote a function in a cpp file, not belonging to any class such as:
char* ConvertWCHARtoCHAR(const wchar_t* wcharString, int intMaxChar)
{
      char *charMultibyte;
      charMultibyte = new char[intMaxChar];
      if(!(wcstombs(charMultibyte,wcharString,sizeof(charMultibyte)) == -1))
            return charMultibyte;
      else
            return NULL;
}

I am sure the charMultibyte is not cleaned up since i am using new but no delete.
I am not using a class here hence i cannot use destructor to clean the memory, any way to solve this problem.

P.S: the reason i wrote this function cause, say if one of the function Foo requires input as char* and i have a wchar_t* with me, i can call directly:
Foo(ConvertWCHARtoCHAR(my_w_char_string));

I have to use Foo a lot of times and everywhere i have cstrings, my application is compiled in Unicode
