Learning goals:

  • Learn how to use the `while` loop to read an integer.


Sometimes, the users of your program do not input exactly what you expect. Perhaps you ask them to put in a positive number, but they may input a negative number on accident. Worst case scenario: this breaks your program!

Write a program called `` that uses a while loop to repeatedly ask the user to enter a positive number and says “Thanks!” once they did and “Oops! Try again.” if they did not.
