**Example Exit modular program:**

In the illustration below, the user

- Whenever prompted for n, entered the two invalid values before finally entering a valid positive integer.

*>> eapplication*

*Enter a positive integer for n: -4*

*Invalid! Enter a positive integer: 5.5*

*Invalid! Enter a positive integer: 10*

*An approximation of e with n = 10 is 2.59*

In order to view the distinction in the approximate value for e as n increases, the user kept choosing Limit & entering larger and larger values each time in the illustration below:

>> eapplication

*Enter a positive integer for n: 4*

*An approximation of e with n = 4 is 2.44*

*Enter a positive integer for n: 10*

*An approximation of e with n = 10 is 2.59*

*Enter a positive integer for n: 30*

*An approximation of e with n = 30 is 2.67*

*Enter a positive integer for n: 100*

*An appoximation of e with n = 100 is 2.70*
