Question

which of the following while loops would continue to loop as long as num has values between the range of 3 - 12, exclusive?
while num <= 12 and num >= 3:

do something with num

while num > 12 and num < 3:

do something with num

while num < 12 and num > 3:

do something with num

while num < 12 or num < 3:

do something with num

Explanation:

Step1: Analyze condition for num between 3 - 12

The condition num <= 12 and num >= 3 ensures num is in 3 - 12 (inclusive).

Step2: Check other options

• Option with num > 12 and num < 3: no overlap (invalid).
• Option with num < 12 and num > 3: 3 < num < 12 (exclusive of 3 and 12).
• Option with num < 12 or num < 3: combines two ranges (not 3 - 12).

Answer:

A. While num <= 12 and num >= 3: # do something with num
