Boundary value

See highlighted part: why is -4 an invalid boundary value, given that t is valid in range [-5, 99]?

To Test for BVA!

You need to test the boundaries of -5 and 99

Following which, ya needa test values outside the range of -5 to 99.

Given -4 > -5 and falls within the range of -5 to 99, there is no need to test for -4.
On the other hand, -6 < -5, and -6 falls out of the range of valid values. Hence, it is important to test for -6.

The 3 Boundary Areas I assume for int t are

1. t < -5
2. -5 <= t <= 99
3. t > 99

That's correct @seanlowjk 👍
