Address any questions or misconceptions the reviewer may have posted. (I like your program! I don't see very many things to nitpick at. Perhaps, instead of using "cout << "---------------" << endl;" you could use something along the lines of "cout << setw(10) << setfill('-') << "-" << endl;" in case you wanted to change that part or prevent changes to how it looks on different screens. Good job on the comments and everything.)

Question-

1. • Address any questions or misconceptions the reviewer may have posted. (I like your program! I don't see very many things to nitpick at. Perhaps, instead of using "cout << "---------------" << endl;" you could use something along the lines of "cout << setw(10) << setfill('-') << "-" << endl;" in case you wanted to change that part or prevent changes to how it looks on different screens. Good job on the comments and everything.) 
   • Indicate how useful the feedback was. 
   • Did you understand the comments/observations/suggestions?
   • Did the review point out flaws/shortcomings in your program?
   • Did you learn anything from the critique?
   • Did the process help you better understand the original programming assignment? would you modify your program based on the feedback/observations?
