6. Identify the error in the following code:

def main():
    print("ADDITION PROGRAM")

    c=(a/b)
    print(c)
    print("....and there's your answer:",c)

13. Most ______________ errors are quite subtle and are much harder to find and fix.

14. Use of a reserved word such as 'print' as a variable would cause an error.

TRUE

FALSE

15. A programmer is trying to work out the no. of months in a year and writes this. What is the error?

MonthsInYear = 13
Average = Total / MonthsInYear

A syntax error - you cannot use the number 13

A logic error as you cannot use a variable called MonthsInYear

A logic error - there are 12 months in a year

A syntax error because the line Average =Total/MonthsInYear is incorrect

16. It is usually the CPU and Assembly language that directly uncovers syntax errors

TRUE

FALSE

17. A logic error is a bug in a program that

allows it to run but causes it to do so with an incorrect outcome due to some logical inaccuracy

is logically sound but has inaccurate syntax

None of the above

is logically correct but creates a logical issue within the compiler if syntax errors are present

18. Data that falls outside of what is acceptable and should be rejected is called….

Abnormal or Erroneous Data

Acceptable Data

None of the above

Borderline Data

19. A system has validation to ensure that only numerical values between 1 and 10 are entered as input. The borderline test data for this could be:

1 and 10

All of the above

3 and 4

20. Data at the upper or lower limits of expectations that should be accepted is referred to as:

Acceptable Data

None of the above

Abnormal or Erroneous Data

Borderline Data

21. An IDE's code editor will usually help with pointing out syntax errors - e.g. pointing out the line in which there is the error

FALSE

TRUE

22. A code editor will always point out and fix a logic error, as these are obvious and crash the program on running it.

TRUE

FALSE

23. The following code has no errors. Which of the following statements is correct?

Dim x As Integer
Dim y As Integer
Dim answer As Integer

x = 10.5
y = 3
answer = x * y
TextBox1.Text = answer

There are no errors

There are at least five logic errors

There are two syntax errors and seven logic errors

There are at least two syntax errors

24. In the following python code, if the user enters 2 and 2, instead of 4, it will produce 22. This is a ….

first = input("Input the first number ")
second = input("Input the second number ")
print("The sum is",first+second)

Major Error

Syntax Error

Logic Error

Minor Error

25. The simplest form of authentication could be:

allowing all users to use the same username and password

entering a passwod up to four million times

entering a usernamd and password and checking it against a database of agreed user entries

26. Authentication methods include :

All of the above

passwords send to phones

patterns to recognise

image scanners

27. Authentication also occurs when you access a website, you request access to the ___________ which hosts the page.

human being

server

validation routine

physical location

28. What is one example of where authentication is required?

getting past the security guard at Microsoft

network cables requiring clearning

None of the above

facebook login

29. Maintainability is also important if a program is going to be robust. Two ways of ensuring maintainable programs is to have good:

passwords and code syntax

users and moral human beings

databases and secure buildings

comments and indentation

30. Entry of a national insurance number may require validation of the following kind:

format check

validation authentication factor check

None of the above

virus check

31. A white list is a list of data that the application will reject and a black list is a list of data that the application will accept as valid

TRUE

FALSE

32. White lists and Blacklists are usually used within:

software development companies

python coding societies

firewall applications

operating systems

33. Having evaluated the visual design of the software, the team must also focus on code structure. Ensuring m___________ and readability is important.

marginality

minimalism

maintainability

mixability

34. There are generally three times of maintainance:

Corrective, Adaptive and Perfective

FALSE

TRUE

35. This type of maintenance is necessary when the client needs the software to run on an environment other than the one that it was originally designed for

adaptive

perfective

none of the above

corrective

36. This type of maintenance is concerned with altering the software to add new features or enhancements not originally requested in the software specification

perfective

corrective

none of the above

adaptive

37. This is a formal document which details the tests to be performed on the software. It will describe the following:

The reason for each test
The data to be used in tests
The expected outcome of each test

Alpha Test

Binary Sheet

Test Plan

Beta Test

38. This relates to the first round of testing. Before releasing new software on to the market, developers will test it in-house.

Alpha Testing

Alpha Testing

Beta Testing

Iterative Testing
