08 - Practice Test

 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 logic error - there are 12 months in a year

  A logic error as you cannot use a variable called MonthsInYear

  A syntax error - you cannot use the number 13

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

  TRUE

  FALSE

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

  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

  Borderline Data

  None of the above

 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:

  3 and 4

  14

  All of the above

  1 and 10

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

  Acceptable Data

  Borderline Data

  Abnormal or Erroneous Data

  None of the above

 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 two syntax errors and seven logic errors

  There are no errors

  There are at least five 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)

  Logic Error

  Minor Error

  Syntax Error

  Major Error

 25. The simplest form of authentication could be:

  None of the above

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