PLEASE READ THE QUESTION CAREFULLY. I NEED THE FULL TASK. IF YOU ARE NOT SURE WHAT TO DO, PLEASE SKIP MY QUESTION. I WILL GIVE NEGATIVE RATING FOR WRONG OR INCOMPLETE ANSWER.

THANK YOU.

EXPLANATION:

We wish to validate the input for types as well as values. There are 3 major concepts to be aware of:

The >> function returns false when an input failure occurs. One possible cause of input failure is a type error.

Since the input stream library maintains an internal state, it needs to be reset after an error. This is done by calling cin.clear().

Since there may have been additional data typed on the error line (e.g., "foo 17" on a line expecting 2 integers), the rest of the line needs to be cleared before retrying. The cin.ignore() function indicates that the rest of the input line already read should be ignored.

QUESTION:

Identify places in your code that need additional input validation, and rewrite the code to handle this. For example, you may write something like the following pseudocode:

output prompt while input n is false reset/clear system output an error message output prompt // assert n contains valid input
