Let's analyze the provided code step by step.
Given input: num = 25
The code evaluates if num
is greater than 20 and less than 22:
IF num > 20 AND num < 22 THEN
-
It checks if
num
(which is 25) is greater than 20:- This condition
25 > 20
is true.
- This condition
-
It checks if
num
(which is 25) is less than 22:- This condition
25 < 22
is false.
- This condition
Since the overall condition uses the logical AND operator, both conditions must be true for the overall condition to be true. Since the second condition is false, the overall condition evaluates to false.
As a result, the program will execute the ELSE
part:
OUTPUT "Invalid."
So, the output of this program when the user enters 25 will be:
Invalid.
