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!

read file, execute functions accordingly

Asked by forums_mp in C++ Programming Language


So I'm given a file with the contents:
 
   set_x, 4, 5
   set_y, 4.6, 4.8
   set_k, 4


Now given a class:
class foo {

public :
  void set_x ( int x, int y ) {}
  void set_y ( double x, double z ) {}
  void set_k ( double z ) {}
  // etc
};

Now within the file set_x represents the function foo::set_x  and the numbers 4, 5 within the file represent the input arguments to foo::set_x.  The question.  How could one read the file and execute the corresponding function accordingly?

One approach I'm investigating is placing the function pointers (i.e a function pointer to a foo::set_x, foo::set_y etc) into a map keyed by a string (which is the string representation of the function i have in the file) .  Now as I read the file I'd call find within the map..  I'm learning std::map as I go so this is a little struggle especially in the function pointer aspect.


A solution with WORKING source would be greatly appreciated.
