Algorithm Verification

Algorithm Verification The following selection statement where X is an integer test score between 0 and 100. input X if (0 <= X and X < 49) output "you fail" else if (50 <= X and X < 70) output "your grade is" X output "you did OK" else if (70 <= X and X < 85) output "your grade is" X output "you did well" else if (85 <= X and X < 100) output "your grade is" X output "you did great" endif output "how did you do?" o What will be printed if the input is 0? o What will be printed if the input is 100? o What will be printed if the input is 51? o What will be printed if the user enters “Wingding”? o Is this design robust? If so, explain why. If not, explain what you can do to make it robust. o How many levels of nesting are there in this design? o Give a set of values that will test the normal operation of this program segment. Defend your choices. o Give a set of test values that will cause each of the branches to be executed. o Give a set of test values that test the abnormal operation of this program segment.
