I am using VS 2008 and cplex 125 version. My computer got broken down and i need to get my code running, I have my thesis proposal this week. And getting the above results. I would appreciate any help.
Thank you so much!

Okay. What's wrong with your code? Some of us may be missing a header that your code relies on, so we can't even trivially tell if it compiles or not.

...and why did you delete the code tags? ;_;
