Doesn't you're compiler return errormessages? Two hints: is string the only thin you use from the std-namespace? And check your variable names.

Additionally, you need to walk through this code very carefully and ask yourself if you are using the appropriate variables for each intended purpose.

Plus, this won't compile:
cin>>fvalue++2;

And don't forget to return 0 from main...
