Need C++ Help. My instructor said the following:

"The following variables should be defined in main(), not global variables: ofstream outf; ifstream inf; What will happen if you move them in main(). Localize them."

So I did this now I am getting an error on line 98. My code bellow followed by screen shot of error:
