## Example exit modular program, MATLAB in Engineering

Assignment Help:

Example Exit modular program:

In the illustration below, the user

•  Chose the Limit;

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

•  Chose the Exit Program.

>> 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
