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!

Reading from a text file: problems in removing the terminating character

Asked by thanesh in CGI Scripting

Tags: , , , ,

Hi Experts,

I am having some problem in removing the newline character from the string that is read from a text file.  I have the source code below.  The problem is if I have the username password pair as myname:password it says that the password has 9 characters.  The chomp seems to not remove the newline character.  Please provide me with some advice as to solve the problem.  This problem preventing me from going further with my assignment.

Thanks a lot,

-Thanesh

use CGI qw( :standard );
