Can anyone help me with 3 questions I have for homework, please? I did the rest but I'm having a hard time differentiating between the 3 questions. They all seem like they're asking the same thing!! The class is Computer Programming using Algorithms and Logic. Thanks, in advance
Probably, but read our homework policy.Quote:

eh, I'm not asking you to answer the questions....I just need help in understanding what the questions are asking.
At the very least you have to post the questions and state why you think they are asking.
Consider 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?"
The 3 questions are:
Give a set of values that will test the normal operation of this program segment.
Defend your choices.
Give a set of test values that will cause each of the branches to be executed.
Give a set of test values that test the abnormal operation of this program segment.
The first two seem to be askin g for the same thing, right? That would be a random #, say 40 that 0<=40<=49
not understanding what abnormal operation is. Is that like entering an invalid character and not a number? Is that what its askin for?
Am I at least close?
Thanks for your help!
Is that you in your avatar, by the way?
They are not exactly the same (just testing "normal operation" is less comprehensive), but it seems to me that you could reuse the test values.Quote:

You might also have learnt that bugs tend to occur at boundaries, so you should select your test values wisely.
That sounds correct.Quote:
