Transcribed Image Text:Assume that variable num is an integer variable which is assigned a random value
from zero (0) to twenty (20). Imagine that there is an if-statement that will
validate the value of num. There are 10 scenarios showing the valid values of num
as shown in the figure below. The valid values are the ones that are NOT shaded.
