After getting a little help earlier on my sentinel mess up, I finally got that to work. However, after a user completes his or her calculation, the program breaks, I want to give the user the option to continue the loop by adding an option to continue by enter y or completely stopping by pressing n. I can't get it to work no matter what I try, so again can someone shove me in the right direction? THANKS!

Move that return 0; to outside of the while loop an give it another try to ask user [Y/N]

Okay, going to try that Lendra.

Okay, that worked, so now all I've got to do is put in the other stuff. Thanks again!
