Error-checking for integers:

illustrations of running this script as shown below:

>> readoneint

Enter an integer: 9.5

Invalid! Enter an integer: 3.6

Invalid! Enter an integer: -11

Thanks, you entered a -11

>> readoneint

Enter an integer: 5

Thanks, you entered a 5

Putting these ideas altogether, the script below loops until the user properly enters a positive integer. There are two sections to the condition, as the value should be positive and should be an integer.

>> readoneposint

Enter a positive integer: 5.5

Invalid! Enter a positive integer: -4

Invalid! Enter a positive integer: 11

Thanks, you entered a 11
